Question about 2002 Chevrolet Astro

1 Answer

Cannot electrically operate door locks 2002 Astro Van

I cannot lock the doors either from passenger or driver side however the side sliding door seems to operate when engaging in park mode. I have applied 12 volts to both doors and the actuators do operate. No fuses are blown. Cannot find any loose cables or connections. Is there a control box or relay I don't know about?
I did check switches on doors and found good continuity.
I'm puzzled!!!! Got any clues I can follow?
Thanking you in advance!

    I would 1st replace the cig liter fuse which is the fuse for door actuators also!



    2nd, Look under the steering wheel under the dash, for a cluster of relays hidden under a plastic and covered container that has 3 relays inside. One of these controls the actuators and since all 3 are the same, reverse the positions and if this works you have a bad relay. Now you must figure which is the bad one or replace all 3 of them. Good Luck

    There is a relay located beneath the dash within a cluster of connectors mounted on the steering column.Look for a square plastic covered box within this maze, within the box you will find 3 relays, they are identical and one of them controls the door actuators. You can reverse all three to see if this solves the problem. If it does I would replace all three which is easier than trying to figure which one is the defective one without a wiring diagram.

    Hope this solves the problem.

    PS: The cigrette lighter fuse supplies power to the actuators.

    There most likely is a relay actuated by the door lock switch (and other things as well). You might be able to find the relay by operating the door lock switch and listening for a slight click -- might help to have two people doing this. The relay may even be in a panel along with others, under hood or dash.

Is there B+ voltage to the switch ? Check for broken wires inside the rubber boot from the body to the door .

I did check switches on doors and found good continuity. ??? Ohm test or voltage
Is there B+ voltage on the orange wire at the drivers door switch ? There are two relays one locks the other unlocks . The Cig LTR fuse supplys B+ voltage to the door switches ,not the actuators . PWR ACCY circuit breaker powers the actuators through the lock / unlock relays ! Check out wiring diagram here http://www.bbbind.com/free_tsb.html

SOURCE: 1999 astro van door lock actuator wont work

Even though it is new there is always a chance the actuator may not be good; I had the same symptoms with 3 of my actuators and had to replace them all about 3 years ago.

SOURCE: My 2002 astro van door locks will not fully

On repairing door locks first check the cigarette lighter and see if it works, the door locks gets it power on the same fuse. If good,you then need to check if 12VDC is at each of the actuators when pressing the switches for the locks. If no power is not at the actuator you should suspect the power lock relay to be defective. This relay is located beneath the steering column within a major cluster of connectors and is located within a bank of 3 relays located within a covered housing. These 3 relays are identical and you can temporaly reverse them to see if this will solve the problem. If it does, GM's part # is RY-232. Can't help you on the rest.......sorry!

Passanger side doors wont lock


From where , any switch ? driver door switch or either passenger door switch . This is a very complex system controlled by modules (microprocessors)

Class 2 and Power Door Serial Data Links
The class 2 and power door data circuits are both serial data links. The serial data circuits replace cables in the vehicle by multiplexing (time-sharing) data to and from each device over a single wire referenced to ground. If the power door serial data is lost, both the rear door module (RDM) and the passenger door module (PDM) enters the sleep mode. With the RDM and the PDM in sleep mode, no power door operations are possible.
Your best bet is to take it to the dealer or an ASE certified repair shop .

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.

Wife taken clio to work with the spare key (no button), she has tried to lock the car but only the passenger side locks, the drivers side is unlocked, how can she lock the drivers door?


Hi,

As you have not stated the Year of Manufacture, I will provide the following possibilities:

Firstly, your wife must be using a sub-key (if no remote function). So, you need to determine if this was a factory supplied sub-key, or was a re-cut duplicate of the master key.

Secondly, the 'most used' key will usually wear out over time (and the driver's barrel lock will sometimes wear in accordance with the most used key), which would mean only that key will operate that door barrel lock successfully.

If the sub-key has not worn to the same degree, chances are the sub-key may not be able to engage properly when inserted into the driver's door lock.

This is common when using a sub-key - sometimes a sub-key won't start the car, but turning the key upside down will often operate the ignition. The same principle would apply to the driver's door lock also.

The key will often operate the door lock if you only insert it about 95% of the way , or simply turn the key upside down and try again.

If the key refuses to operate the driver's door, the other alternative is to enter via the passenger side and reach over to lock the driver's door from the inside. Then lock the passenger door behind you.

However, this is a major hassle, so I would recommend you obtain a replacement Renault key "FOB" remote (you can get these off Ebay reasonable cheaply - supplied with instructions) and program it to your vehicle yourself. This will enable both of you to have a central locking remote key fob.

Note: the remote fob programming feature will obvioulsly depend on the year of manufacture for your vehicle though.

The power side passenger door for a 2001 Chevy Venture van works every so often. The door doesn't move when the button is pressed on the panel in the headliner. The key remote doesn't work most of the time...


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.

1992 Subaru Liberty wagon - cannot lock front passenger door.


Check the alignment with the door pin. Might be out of adjustment and will not let the door close all the way. That will cause the lock to not be operable. Good luck and have a great day.

I have a 2003 Astro - interior issues


I had the same problem and found that my sliding side door "closed" switch, which is small and round and in the door frame, was not being pushed open all the way when the door was closed! As soon as I put a credit card in the spot where the switch hits the door all the locks and lights worked again. So I just taped a washer to the door where the pin switch hits it for now. The computer thinks the door is still open and will not alow them to lock and the lights won't operate right either.

Driver and Passenger auto door locks are inop.


Sounds like bad wiring, or bad door lock actuators. Check for power while locking/unlocking the doors.
