    2006 Tahoe, my back hatch will not lock, nor will the window. All of the other doors lock just fine. I have to back my truck up tp my garage door so noone can open it and steal my stuff. I am looking to see if the fuse is seperate and if so I will replace it and see if that helps. If not I guess I will have to pay someone to fix it.

    2005 Dodge Caravan. I am locked out of the rear LIFTGATE. is there any way for me to open the liftgate from the inside. I noticed a small round plastic plug in the inside near where the lock is located. Is that possibly an access port??

    Granddaughter left right rear car door open after I had manually locked the car. I shut the door and now my key will not unlock the vehicle. Does the computer have a certain period of time before it will allow my key to open the door?

Doors unlock on 2005 Chevy Taho but the rear hatch won't. It does not even click when you press button. It does not have a key acess. Is there a manuel opener?? Or a fuse. Even the glass hatch will not unlock.

I was able to find this information but can't find details other than removal of the fascia.
Part Number - 15808595

Actuator is most likely bad. i just took mine apart, and it seems gears are stripped. has a work gear thats steel and the toothed gear is nylon, and worn out.

if anyone can get a part number, that would be good.

I have a 2005 GMC Yukon that the rear hatch does not lock. Wouldn't be a problem but no manual key hole to lock it. Must be some kind of lock sensor. Is on the driver door panel or by the hatch?


The rear hatch locking is computer contolled .
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:
• An open ECC fuse
• An open or short to ground in the liftgate lock relay battery positive voltage circuit
• A faulty liftgate lock relay
• An open or short to ground in the liftgate lock relay control circuit
• A short to ground in the liftgate lock actuator lock control circuit
• A faulty BCM

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 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)

If i were to guess i would say you mite need a new lock actuator , but i don't guess . You could take the hatch inside panel off an check for B+ voltage for the lock actuation as someone pushes the switch . Or have it checked for codes .

--------------------------------------------------------------------------------
Do This
Don't Do This

Reposition liftgate lock cylinder wave washer and adjust lock rod.
DO NOT replace the liftgate latch or actuator.


Condition
Some customers may comment on one or more of the following conditions:

• The rear liftgate glass may not lock when using the remote keyless entry (RKE), key fob transmitter or door lock switch unless the lock is pressed a second time.

• The rear liftgate or glass locks, but may be unlocked when the rear liftgate lock cylinder button is depressed.

• The rear liftgate locks but the liftgate glass may not lock.

Cause
These conditions may be caused by one or all of the following:

• The rear liftgate cylinder lock rod may be out of adjustment.





• The wave washer on the liftgate lock cylinder may be out of position with the cup side down.

• Excessive movement or slack in the lock rods at the liftgate bell crank assembly.





• The liftgate lock cylinder pawl may contact the rear liftgate glass latch when the lock cylinder button is depressed.

Correction
Important: Do Not remove the rear liftgate lock cylinder from the vehicle to perform this repair.

Reposition the rear liftgate lock cylinder wave washer and adjust the lock rod using the steps below.

Verify the customer's condition.

Open the liftgate.

Remove the upper liftgate garnish molding.

Remove the rear liftgate trim panel.

Remove the cylinder lock rod from the threaded lock rod retaining clip.

Tip
Place the tip of a screwdriver blade into the opening of the C-clip and slowly rotate the screwdriver to pry out the C-clip from the shaft. Then use needle-nose pliers to remove the C-clip.

Remove the C-clip from the rear liftgate lock cylinder push button and remove the wave washer.

Install the wave washer with the cup side up.

Position the wave washer with the curved edges of the wave spring parallel to the tabs on the lock cylinder shaft.

Important: Use needle-nose pliers to slightly squeeze the C-clip back into shape. Make sure the clip seated, you should feel a snap and hear an audible click.

Install the C-clip onto the shaft and in the slot using needle nose pliers. Then rotate the pawl several times to make sure the C-clip does not rotate. If the clip rotates then the clip is not fully seated.

Position the lock cylinder pawl to the full clockwise position.

Pull up on the cylinder lock rod to remove any slack in the bell crank.

Install the cylinder lock rod into the threaded lock rod retaining clip while removing any slack from the lock rod linkage.

Close the lock rod retainer clip.

Close the liftgate assembly.

Open the liftgate glass while keeping the liftgate closed.

Use the key fob to cycle the liftgate to the lock and unlock position while inspecting the rear liftgate pawl. The lock cylinder pawl should have clearance between the latch as shown above. If the pawl is contacting the latch, readjust the cylinder lock rod.

Verify that the customer's condition has been corrected.

Install the rear liftgate trim panel.

Install the upper liftgate garnish molding.

I just bought an equinox 2005 LS and I dont know how to lock the rear door.


To unlock the liftgate, press the unlock button on the Remote Keyless Entry (RKE) transmitter twice or use the power door lock switch.
To lock the liftgate, press the lock button on the RKE transmitter or use the power door lock switch. The liftgate does not have a key lock cylinder.
To open the liftgate, pull up on the handle located in the center of the liftgate.
When closing the liftgate, use the molded handles to pull the liftgate down. Push the liftgate closed until it latches.
