SOURCE: Security Light always on, door lock fuse keeps blowing

This is most likely a problem with your Passlock anti-theft system which is known issue with these cars. Passlock is a "passive" anti-theft system, which means that it will disable your ability to start the car if it thinks there is a problem. The three components that can cause this are: 1) Ignition Switch, 2) Ignition Cylinder, 3) Body Control Module (computer). The dealer is the only one who can solve this problem (unless you can bypass it, but it is not that easy). Estimated repair from most dealers is $800 and up.

It sounds like you've got a broken wire on the drivers side door. Usually this occurs at the flex point of the wiring harness. Peel back the outer covering carefully exposing the wires inside. Repair any broken or those about to break. Solder & retape or shrink rap with heat gun.Hope this helps. Good luck!

You have a intermittent condition. To isolate the cause: 1.Disconnect the drivers door lock/unlock switch from the connector. Drive the vehicle and see if your random lock/unlock condition has stopped. If it has, replace the switch. If it hasn't:
2. You have a grounding problem or a problem in the BCM (Body Control Module) and should have a technician use a Tech 2 Diagnostic Link Tool to access the BCM computer to obtain any fault code data to help correct the condition.

Hi,
Plz explain...are the locks supposed to lock/unlock when you put the car in Drive/Park, or not?

Does the lock/unlock SWITCH on the DRIVER'S door work/not work? If applicable, does the PASSENGER's door lock switch work?

2005 Chevrolet Tahoe Power Windows and Power Locks not working.


The power windows an power locks are controlled by a module , DDM - driver door module . As far as the locks locking when you put the vehicle into reverse an unlocking when you put the vehicle into park , that's how there are suppose to work , automatic lock an unlock feature . When you put the vehicle into any gear from park the locks should lock . Did she hit window lockout function ?

The power door lock system consists of the following components:
• The driver door module (DDM)
• The passenger door module (PDM)
• The body control module (BCM)
• The driver information center (DIC)
• The rear door lock switch
• The door lock relay
• The door unlock relay
• The liftgate lock relay--utility vehicles with liftgate only
• The reversible door lock actuators in each of the doors and liftgate
• LOCKS 20A fuse (rear lock/unlock relay supply voltage)
• ECC 10A fuse (liftgate lock relay supply voltage .

Programmable Automatic Door Locks
The automatic door lock feature can be programmed to control the door lock system. The automatic door lock feature is factory programmed to have all doors lock and unlock. For detailed instructions on programming the automatic door locks, refer to Vehicle Personalization in Personalization.
When the automatic door lock feature is programmed to control the door lock system, the driver door module (DDM), passenger door module (PDM) and body control module (BCM) will lock the vehicle doors if the following inputs are true:
• Ignition 1 input is active.
• All door jamb switch inputs are inactive.
• Cargo door or liftgate/liftglass ajar inputs are inactive.
• Transmission is shifted out of park.
This automatic door lock function will only occur once per ignition cycle unless, a door jamb switch input changes state to active and back to inactive. Then the DDM, PDM and BCM will lock all doors again.
Once the automatic door lock feature has locked the doors, the BCM will then unlock all the doors when the transmission is shifted into park.
Driver, Passenger and Cargo Door Lock System Operation
The front power door lock switches are integral components of the driver door module (DDM) and passenger door module (PDM). The switches are two position normally open rocker switches. When placed in either the lock or unlock positions, the switches provide a direct input to the DDM or PDM. The DDM or PDM monitors these inputs and sends a Class 2 message indicating a change in the switch's respective position. Modules which activate the power door lock motors receive the Class 2 message and activate the motor in the appropriate direction to lock or unlock the vehicle's doors and liftgate. The rear door lock switch provides a lock and unlock signal to the body control module (BCM). The BCM upon receipt of a lock or unlock signal will control the rear door lock relays and also send a Class 2 message to the DDM and PDM to perform the appropriate function.
The modules which activate the power lock motors are:
• The DDM (driver door lock actuator).
• The PDM (passenger front door lock actuator).
• The BCM (both rear door lock actuators and cargo door/liftgate).
The DDM and PDM are directly connected to the respective door lock actuator through the door lock motor lock and unlock circuits. Once a door lock or unlock request has been received, the module will supply battery voltage to one side of the actuator and ground the other causing the doors to lock or unlock.
The rear passenger and cargo doors differ slightly in that they use lock and unlock relays. The relays supply and coil sides receive a constant voltage through the battery voltage supply circuit. The normally closed contacts are connected to ground and the control side is connected to the BCM. Once a door lock or unlock request has been received by the BCM, the BCM will ground the control side of the appropriate relay. This energizes the relay and allows voltage to be applied to either the door lock motor lock or unlock circuits. since the other side of the door lock actuator is connected to the normally closed contacts of the opposing relay to ground, the doors lock or unlock.

My automatic door locks keep clicking up and down even when the car is parked..


I found that water had dripped into the power lock switch and shorted out the circuit board. This caused all of the problems that you described above. Replace your driver side door lock switch and you should be set.

Power locks not working right


Hey, this might work.....get in truck, close doors, put key in ignition in lock position.....hold down the door lock button on driver side door control and wait for the lock control to be displayed on the information screen(odometer read-out).....it should say like lock 1, lock 2, lock 3, lock 4.....or something, I always reset mine to LOCK 1, to do this hold the odometer reset button on dash for a sec or two til it changes settings, then release, repeat till you get to LOCK 1, then quickly press and release odometer reset button to exit program, this is the function to lock doors over 15 mph and when out of park and to unlock doors when returned to park......yours' might be set to another function number....try it out, let me know if this helps.........good luck!
