SOURCE: My 2006 Yukon tailgate will

I have the same problem. This is a faulty actuator switch according to GMC which controls the tailgate and the hatch window. My 2006 has 90,000 miles on it (I purchased new). Warranty is not an option and cost is estimated @ $600.00 in Arizona. As far as I am concerned, it is safety related issue and should be a recall since there isn't a mechanical way to open the tailgate or window as an escape route in the event of failure.

SOURCE: Power Door Lock Problem

The last post by maddog1321 was exactly what I had with my right rear door. The electric locks would not lock and unlock, and you almost couldn't do it manually without my feeling I was about to break something. I took the door panel off, oiled everything and got no relief. Finally, I saw the above post and drilled out the aft-most pop-rivet. THE WINDOW WORKED PERFECTLY! I didn't drill out the forward (closest to the handle) pop-rivet because I wanted to do one at a time so the solenoid would not fall out of place. I then put a new pop-rivet in place of the one I drilled out. I then reinstalled everything and the locks work like new.

SOURCE: Yukon xl rear door won't unlock and there is no manual lock.

I fixed mine by using fine steel wool to clean the brass contacts located at the right upper door frame on the right door as viewed from the rear of the vechicle.

SOURCE: All of the door locks but one on our 1999 GMC

there is a relay but if it were bad none of your locks would work. your problem is the door lock motor it is a little electric motor that actuates the lock. its also called a door lock actuator. kind of expensive and a little difficult to replace.

My 2009 Pontiac G5 started doing this about 3 months ago. On startup, the door locks make noise and it takes a while to shift out of park


Have the vehicle checked for DTC'S diagnostic trouble codes stored in the BCM - body control module . Everything is electroniclly controlled .
Automatic Transmission Shift Lock Control Description and Operation
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
• The automatic transmission shift lock solenoid (serviced as the automatic transmission shift lock actuator), as well as the body control module (BCM) and the engine control module (ECM). The shift lock solenoid is located within the floor shift control assembly with vehicles equipped with floor shift.
• The BCM controls the voltage to the shift lock control solenoid through the shift lock control solenoid controlled voltage circuit. The following conditions must be met before the BCM will remove voltage from the shift lock solenoid:
- The ignition is in the ON position.
- The engine control module (ECM) sends an input via GMLAN serial data to the BCM indicating the transmission is in the PARK position.
- The BCM determines the brake pedal is applied according the brake pedal position.
Since the shift lock control solenoid is permanently grounded, the BCM supplies voltage to the automatic transmission shift lock control solenoid, mechanically locking the shift lever in the PARK position as the solenoid energizes. When the brake pedal is applied, the BCM turns the control voltage output of the shift lock control solenoid OFF, de-energizing the shift lock control solenoid. The de-energized solenoid releases the mechanical lock allowing the driver to move the shift lever out of the PARK position. When the transmission is out of the PARK position, the shift lock control solenoid remains de-energized.
During remote start operation, the BCM will energize the shift lock control circuit, locking the shift lever in the PARK position.

The BCM supplies and monitors a reference voltage to the door lock switch through the door lock switch lock/unlock signal circuit. The door lock switch also receives a constant ground source. If a door lock switch is placed in the lock position, the reference voltage is taken directly to ground and the BCM senses 0.0 volts on the signal circuit. If a door lock switch is placed in the unlock position, the reference voltage is taken to ground through a 15k ohm resister that is internal to the door lock switches and senses approximately 2.9 volts on the signal circuit. This is how the BCM determines what portion of the door lock switch was activated.

2002 chevy Blazer 2 door. Power locks,and liftgate stop working.The locks will engage when I shift to drive and will disengage when placed in park. Where do I start?


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?

What can cause doors lock to unlock and then lock again while driving


The indicator for park/neutral is changing on the dash without you moving the shifter?
If so...the park/neutral switch on the transmission...(or could be on shifter housing) is informing the lock control module/body module... that the vehicle has been put in park...thus the door unlock actuation...then..apparently the switch is erroneously informing the lock module that it is in neutral...drive...thus locking the doors....could also be a fault in the general body module...which ..most likely...controls most of the body systems via CAN BUS....Controller Area Network system....
Odd that no codes are in the body/lock module....make sure your scan tool is indeed able to access the body control systems...if not...you need to find a location that will provide that service.

Locks unlocking while driving.


Has the switches on your driver or passanger side gotten wet anytime lately? I had to replace the switch that you actually click to unlock and lock because it had gotten wet and my car would set it's alarm after waiting 30 seconds when you would try to open the door. Changing this is an easy and cheap fix. I hope it helps!

The battery in my 2006 pontiac vibe went dead. I recharged it; however, the setting for the door locks changed. It now unlocks automatically when I turn the car off instead of when I put the car in park. I...


The 2006 Vibe no longer has that feature. It was discontinued after 2005. I have the 2005 so I know how to change it. If your 2006 is able to change then here are the directions from my 2005.
Programmable Automatic
Door Locks
If you have an automatic transaxle, your vehicle is equipped with an auto door lock/unlock feature which enables you to program your power door locks.
Your vehicle left the factory programmed to Mode 4.
The following is a list of the available programming options:
Mode 1: All doors and liftgate lock when the shift lever is moved out of PARK (P) with the ignition on and all doors and liftgate closed. There is no automatic door unlocking.
Mode 2: No automatic door locking or unlocking.
Mode 3: All doors and liftgate lock when the shift lever is moved out of PARK (P) with the ignition on and all doors and liftgate closed. All doors and liftgate unlock when the shift lever is moved to PARK (P) with the ignition on.
Mode 4: All doors and liftgate lock when the shift lever is moved out of PARK (P) with the ignition on and all doors and liftgate closed. All doors and liftgate unlock when the ignition switch is turned from ON to ACC or to LOCK.
To change the mode you are in, do the following:
1. Set the interior lamp control dial to the door position.
See Interior Lamps Control on page 3-16.
2. Move the shift lever into PARK (P) and close all doors and liftgate.
3. Turn the ignition to ON.
4. Within five seconds after the ignition is turned to ON, press and hold the power door lock switch in
the lock position for about five seconds.
5. The interior lamp will flash to indicate that the mode has been changed. For example, if the lamp flashes once, the function has been changed to Mode 1.
If the battery is disconnected or run down, the mode is changed to the initial mode which is Mode 4.
