Right rear door lock actuator doesn't work

The right sliding door has two actuators, one doesn't work, one does work and it looks like the wires going to faulty one are bad or not getting electricity (tested). Everything works on the door except for two wires to one actuator. The wires go to the bottom front of door where 7 contacts go up against 7 other contacts on the pillar. I tested all the pillar contacts, and just the bottom 2 gave a reading when locking/ unlocking, i'm thinking the bottom two is just for the one actuator and wires that work, and the two right above that are for the other actuator, how can I fix the wires that go from the front pillar to wherever it goes?

SOURCE: Driver side power lock will lock but not unlock

The only way to really see the problem is by removing the door trim panel. This will allow you to see if is the actuator is moving, and how far, along with noting any interference of lock linkage movement. Hope this helps.

2002 Cadi Deville, can't get any locks to operate with remote or dash push buttons, the remote operates everthing but the locks! When the remote door lock is pressed, lites flash,horn blows locks not.


Power Door Lock Operation
The vehicle is equipped with power door locks. Each lock actuator is powered and controlled by the door module mounted in the individual door, but the rear integration module (RIM), which is the master control for the door lock system, determines when the lock functions are permitted. The RIM receives and examines the requested lock function from the individual door modules, or from the remote function actuator (RFA) via the class 2 serial data circuit. The RIM also examines the transmission shift selector position and the ignition switch position information available over the Class 2 serial data circuits. If the RIM determines that a lock or unlock function is permitted, it sends a class 2 message back to the individual door modules commanding them to perform that Lock or Unlock function.
Power Door Lock Components
The power door lock system consists of the following components:
?€¢
Driver door lock switch


?€¢
Passenger front door lock switch


?€¢
LH rear door lock switch


?€¢

Driver door lock doesn t work


You need to test the parts. Does the switch have continuity when actuated? If yes, check the wires for continuity. Will the actuator work when you apply power directly to it? If yes, test the wiring.

2005 dodge durango rear hatch will not unlock to open


I own a 04 durango and the door lock actuator froze up internally and I could not open the rear hatch. After hours of research on my computer nothing seemed to fix the problem. I eventually figured it out myself. You must pull the screws out of the molding on the inside of the rear door. You can now pull the molding toward you and look down at the actuator and latch. You can pull on the molding quite a bit if necessary. I never broke mine and I was pretty agressive with it. Now, on top of the whole mechanism is the lock actuator. There should be a white plastic lever sticking out towards the driver side. If you can slide it from back to forward "forward is front of vehicle", the lock should be working. If not your door is not unlocking. My durango had 3 Torx screws on top of the actuator. Remove them. This will take the actuator off of the latch. Now that the actuator is not binding or holding the lock from moving, again try to move the white plastic lever towards front of vehicle. It should click and you should be able to open the door.

The proper way would be to look at a wiring diagram an test the electrical circuit's with a DVOM - digital volt ohm meter . Do you know how to test automotive electrical circuit's ?
Electric Testing Techniques You Need to Know
The Trainer 32 How To Read An Automotive Block Wiring Diagram
Free wiring diagrams here http://www.bbbind.com/free_tsb.html
Enter the vehicle info. year , make model and engine size . Under system click on body & accessories ,then under subsystem click on power sliding door . Click the search button then the blue link. Looking at the diagram you will see a control module is used .
Also reading factory service info. on how it works would be a good idea.

Rear Side Door Actuator Control Module
The rear side door actuator control module is capable of on-board diagnostic functions described in On-Board Diagnostic Features . The rear side door actuator control module monitors the door position at all times including during manual operation. After activating the on-board diagnostic modes, loosing battery voltage, or ground to the rear side door actuator control module the Power Sliding Door (PSD) Re-Initialization procedure must be performed in order for the rear side door actuator control module to correctly determine the door position.
Power Sliding Door System Description
The power sliding door system(s) can operate correctly only if the power sliding door is in proper mechanical condition. Any mechanical problems will affect the power sliding door operation and must be repaired before attempting to diagnose the power sliding door system. Manually open and close the power sliding door to determine if the door moves smoothly and without excessive resistance or binding. The power sliding door must also latch and unlatch without the use of excessive force. At any time during power sliding door open or close operation, excessive resistance to the door movement will cause the power sliding door to stop and reverse the direction of travel.
The power sliding door will operate only when the power sliding door on/off switch in the overhead console is in the on position. At anytime during power sliding door operation the on/off switch may be turned to the off position and the system will quit any function in process. The power sliding door will not open unless the transmission shift lever is in the park position and the door is unlocked. When the sliding door security lock is in the locked position the power sliding door will not open from the inside. The power sliding door close function will operate when the vehicle is in gear. The power sliding door module uses the VSS signal to determine if the vehicle is moving during a power sliding door close function. The momentum of the vehicle moving forward adds resistance to the door closing operation. When the rear side door actuator control module determines the vehicle is moving forward while closing the door, current flow through the actuator motor is increased instead of being reversed. The VSS signal circuit is supplied battery positive voltage through a resistor then monitored within the rear side door actuator control module. The VSS signal circuit is then pulsed to ground, or pulled low by the powertrain control module in relation to vehicle speed. The sliding door alarm will sound repeated short tones whenever the power sliding door system is turned on and the door is open while the transmission is out of park.
When the power sliding door system is on and manual operation of the power sliding door is detected the rear side door actuator control module activates the power assist feature. When the power assist is activated the power sliding door will continue to open or close without any further manual effort.
The power sliding doors may be operated using the Remote Keyless Entry System. The keyless entry transmitter will have one OPEN/CLOSE button with a van symbol on it for each power sliding door. The power sliding door ON/OFF switches in the overhead console must be in the ON position in order to operate the power sliding doors using the keyless entry transmitter. When a right hand power sliding door OPEN/CLOSE function is activated using a keyless entry transmitter the exterior lights will flash once indicating the RKE module has received the OPEN/CLOSE command. When activating a left hand power sliding door OPEN/CLOSE function with the keyless entry transmitter the exterior lights will not flash.

On-Board Diagnostic Features
The left and right power sliding door systems operate as independent systems. The on-board diagnostic modes are entered and operate the same in both systems.
The power sliding door systems are capable of the following on-board diagnostic functions:
• Diagnostic Mode 1: An audible signal indicates the diagnostic trouble codes stored by the rear side door actuator control module.
• Diagnostic Mode 2: An audible signal indicates when inputs to the rear side door actuator control module are active.
• Diagnostic Mode 3: Performs an output test of the sliding door unlatch actuator.
Entering On-Board Diagnostics
The on-board diagnostic modes can only be entered in a sequential order from modes 1-3.
• Enter the right power sliding door system on-board diagnostics using the right B-pillar open/close switch and the right on/off switch in the overhead console.
• Enter the left power sliding door system on-board diagnostics using the left B-pillar open/close switch and the left on/off switch in the overhead console.
1. Both power sliding doors must be closed and in the latched position.
2. Place the ignition switch in the OFF position.
3. Place the on/off switch in the overhead console to the OFF position.
4. Press and hold the B-pillar power sliding door open/close switch.
5. While holding the open/close switch, operate the on/off switch through 10 ON and OFF cycles within 10 seconds stopping in the on position.
6. The sliding door alarm will sound 1 long tone indicating diagnostic mode 1 is active.
Diagnostic Mode 1
Upon activating diagnostic mode 1, DTCs will begin to be signaled by the sliding door alarm. The DTCs are 2 digit codes and the codes are represented by the number of buzzes for each digit of the code number. For example a DTC 12 is represented with the following sequence: buzz, pause, buzz, buzz, long pause. Each DTC will be signaled 3 times before proceeding to the next DTC. Refer to Diagnostic Trouble Code (DTC) List . The DTCs will continue to be repeated in this manner until the on-board diagnostics are exited or mode 2 is entered. When exiting the on-board diagnostics all stored DTCs will be erased from the rear side door actuator control module memory.

Hi ,is it possible that the rear doors lock actuators stop working at the same time and should be both replaced or there might be other cause rather than the actuators it self?


see if power reaches the actuators when using the lock/unlock, if it does, the actuators are dead , you can test it by removing the door panel and disconnecting the wires going to the actuator and using a test light or a voltmeter on the wires, (if there is only one wire its the positive terminal)

How do you get the acuator out to replace?


Repair would be to replace and I have no direct knowledge of the 99 model but my 2001 wasn't so hard and I would guess that the 99 will be a similar replacement.

  • Remove the door panel, on the 2001 it's 2 screws located on the inside door handle, 2 on the bottom and one at the top near the mirror.

  • With that removed you take off the foam panel and expose the inside of the door.

  • The lock actuators are easy to find, they are attached to the lock rod. There is one electrical connector on it that is taken off by lifting the lock clip using a slot screwdriver then just pull the connector out.

  • The actuator itself is a bit odd to get out.
    To look at the new one it seemed to me that it would click in from the top but after doing the first one I saw that it actually SLIDES in from the direction of the outside of the door.
    I found a very thin narrow **** located where the striker hits the lock on the outside door jam and this goes directly to the side of the actuator. I fashioned a tool from a narrow putty knife then pushed it into the **** and then pushed onto the actuator releasing the little friction clip that you can see on the new actuator.

    You then have to push and push this whole thing towards the outside wall of the door which doesn't go too easily. On my passenger side i resorted to a long slot screwdriver to use as a lever to help slide the thing forward because it didn't want to budge.
    The good thing though is that the new ones slide right into place easily.

  • Another thing, the pin on the actuator that moves the lock-rod just sits inside the lock-rod, there is no mechanical attachment and it fairly loose so no need to worry about that part of it.


Another Procedure Write-up
  1. Remove the retainer screw from the door handle cover and remove.
  2. Remove the screw from the bottom left corner of the door panel.
  3. Pull the door panel away from the door, starting at the bottom (may need to start with door half open then close fully to remove). Lift up and off the door.
  4. Peel back the door insulation by working gently at edges .
  5. Remove 3 black screws from the face of the door latch mechanism.
  6. Disconnect the controller arm at the top of the door latch mechanism that connects to the outside door handle. The plastic connector will push up from the metal arm after the locking tabs are pushed in.
  7. Open the door half way and remove the 3 screws from the side of the door around the door latch.
  8. The door latch mechanism is now able to be removed out from the inside of the door. The black wire cables may need to be removed from some of the retaining clamps.
  9. The lock actuator can be removed. The actuator body will twist out of the spring clamp. Then the bar at the end of the actuator can be removed by turning

Hope helped with this (remember rated this help) Good luck.

2006 Tahoe Z71 Lift Gate Will Not Unlock With Remote


Take the liftgate inside panel off an check the wiring , connections etc....
rear door hatch lock repair GMC Chevrolet
chevy tahoe lift gate not opening
The liftgate will lock any time the vehicle is shifted out of park on vehicles equipped with an automatic transmission and at vehicle speeds exceeding 5 kph with manual transmission. This happens in conjunction with auto door locks if enabled or independently of auto door locks if the feature is disabled. This ensures that the liftgate is locked anytime the vehicle is shifted out of park or when the vehicle is in motion.
The liftgate lock relay supply and coil sides receive a constant voltage through the battery voltage supply circuit and the ECC fuse. The normally closed contact is connected to ground and the control side is connected to the body control module (BCM). A lock function will occur when a door lock switch activation, keyless entry lock transmission, auto door lock function or a liftgate lock function has been received by the BCM. The BCM will then ground the control side of the liftgate lock relay. This energizes the relay and allows voltage to be applied to the liftgate lock actuator lock control circuit. Since the other side of the liftgate lock actuator is connected to the normally closed contacts of the door unlock relay to ground, the liftgate will lock. When an unlock function occurs the BCM will ground the control side of the unlock relay and the rear doors and liftgate will unlock.
The BCM also runs diagnostics on the liftgate lock relay control circuit and will set DTC B3825 as current and also send a Class 2 message to the DIC. The DIC will display REPLACE LIFTGATE FUSE to inform the driver that a fault has been detected in the liftgate lock circuit and that the liftgate is not locked. Faults that will set the DTC and cause the DIC to display the message could be any of the following

1996 Ford Bronco door lock actuator


These directions might sound a little goofy. I'm trying to orient your location with front and rear rather then left and right because it depends on which door you are working on. Front is towards front of rig and rear, oh I think you get it.
1. Close window on door. 2. Using a flat screw driver pop off trim under inside door handle. I think there is a groove in the plastic to which the screw driver can be inserted. Remove screw. 3. Using same screw driver pop off trim panel with door lock and window control switches. Start lifting from end located at panel closest to the front of the rig. The panel towards the back end has a pivot point which holds the back of the panel into the arm rest. Dis-connect the two switches from the trim panel. 4. Again, using flat screw driver, pop off the trim pannel located at the upper door/window frame nearest the back of the rig. Remove screw. 5. Lift up the door panel to remove. Be careful the light bulb is attached to the door panel. Rotate light socket 90 degrees and remove. 6. From the rear of the door pull back the platic stick-on barrier. Don't remove the whole thing just pull it leaving about half of it towards the front of the door stuck on. 7. Remove the one 11mm bolt, located towards the bottom of door, which holds the rearwindow guide. Don't remove the two 11mm bolts which hold the horizontal brace. Nothing else needs to be removed, leave all rods and attachments in place. They all attach the the door latch and are not of any further concern.
8. Now the easy part. The actuators and door latches are separate components. The actuator slides onto the door latch via two metal guides located on the door latch. The actuator is held into place with a plastic locking tab. The locking tab is part of the actuator housing. 9. This tab has to be pushed in to release actuator from latch. 10. Find on ouside of door - rear where the latch fingers? (I don't know what else to call them) are located in the notched door frame. At the bottom of the notch is a very narrow opening, just a ****. This **** allows access to the locking tab on the actuator. 11. Orient the screw driver in the end of the **** closest to the interior. Working on a right door, looking at the locking fingers, facing the front of the rig, your screw driver would be inserted at the left side of the ****. Pushing a flat screw driver into the **** will push the locking tab allowing the actuator to slide off the door latch. 12. A flat screw driver or other small pry tool can be inserted between the actuator and the door lock to help slide the actuator off the metal guides. The pry unit can be inserted where the rod from the interior manual door lock stem is attached. Mine had a yellow snap/flip keeper. 13. The actuator slides off from the interior towards the outside door panel. 14. Simple put pressure onto the locking tab with one screw driver and gently pry with the other one and the actuator should slide right off.
15. I picked up an actuator at a u-pull it wrecking yard for five bucks and it worked fine. Dealer wanted $90.00 and auto parts wanted $127.00. When I pulled my actuator from the wrecked rig all door panels and interior where stripped. It took me literally 20 seconds to pull the actuator. 16. To install new unit slide actuator onto door latch rails and let locking tab click into place. You might have to manually move the interior door lock stem up and down until the finger on the actuator lines up with a hole on the plastic part of the interior lock stem.
16. I Want to thank TommyRox in Texas on Ford Truck World and rivguy on automotiveforums.com for their posts.
