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 .

Back window is stuck


First be sure the auto-lock is not on and that the entire liftgate can be opened.

Look for the small rubber button above and on the right side of the license plate. Try pushing that button to see if the rear window hatch pops.

If these efforts don't work, check the fuse associated with the "luggage compartment lid release switch"... it's a 20 amp fuse possibly located in slot 22.

A last resort would be removing the interior panel of the liftgate and locating the latch release for the hatch. You can find a schematic of the rear liftgate in an Internet search. Good luck!

2004 lincoln navigator ,doors will not open rear hatch will not unlock


The door locks are controlled by the vehicle security module (VSM). It gets power from fuses 30, 5, 6, and 40 in the central junction box (CJB). You say you checked these and all are OK. Therefore the problem must be in the door lock actuators, the door lock relays, or the door lock switches. I doubt that all of these are defective, so the VSM may be defective.

The liftgate is controlled by the power liftgate module (PLM), althogh the motor in the liftgate glass actuator is controlled by the VSM. The PLM gets power from fuses 105 and 5 in the CJB. If the PLM is assumed to be OK, the source of the problem could be the liftgate unlatch motor, the liftgate cinching motor, the L/R liftgate obstacle detection strips, the liftgate home position switch, the liftgate fork bolt/detent switch. or the power liftgate open/close switch

TrailBlazer remote lock, rear defroster, and rear windshield wiper failed simulatneously


Hello and welcome. all these functions run off the liftgate module. the liftgate module is located in the rear hatch. also the replacement liftgate module has to be programmed with software for it to function correctly


  • Disconnect the electrical connectors (3) from the module as necessary.
  • Remove the bolts that retain the module to the liftgate.
  • Remove the module from the liftgate.

    When i use the key fob to lock the doors the back glass dont lock, ???????


    This solution applies to models:
    2002-2007 Chevrolet Trailblazer, Trailblazer EXT and Trailblazer SS
    2004-2007 Buick Rainier
    2002-2007 GMC Envoy, Envoy XL, and Envoy Denali
    2002-2004 Oldsmobile Bravada
    2005-2007 Saab 9-7x

    Condition/Concern:
    Rear liftgate glass will not lock when using the key fob or door switch unless the lock button is pressed a second time. All other doors will lock normally. This could be the result of the liftgate glass lock rod not adjusted correctly. This lock rod travels from the liftgate lock actuator to the glass release push-button cylinder.

    Recommendation/Instructions:
    Remove the inside rear liftgate trim panel. Disconnect the threaded lock rod clip at the end of the push-button glass release and rotate this clip 1 complete turn at a time making the lock rod longer. This will be the only threaded lock rod visible when the trim panel is removed and the liftgate is raised.
    Note: For the rear glass to release, the rear liftgate latch must be in the closed position. For test purposes only, this latch can be made closed to make this lock rod adjustment.

    Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

    Emergency trunk release if you need it open now. from there you could try to fix the problem or take it to your dealer, you may still be under warranty 1. Remove trim plug to expose the access hole in the trim panel. The access hole is located on the inside of the liftgate. 2. Use a tool (flathead screwdriver) to reach through the access hole in the trim panel. 3. Pry the left release lever up to the unlock position. Pry the right release lever up to unlatch the liftgate. 4. Reattatch the trim plug. this information can be found on page 2-13 of your owners manual
