SOURCE: hatch-back door will not open

I can say I have had the same problem, only the back doors and the rear hatch/glass won't open using keyless remote from them freezing this Winter.  The front two driver/passenger doors will unlock with keyless remote but none of the rear doors, hatch or glass.  Since I had to replace the stoplight bulbs in the rear with one not working and I don't need a ticket on Memorial Day weekend (need to replace 2 at the same time is wise according to any good mechanic), I had to get the rear hatch open to get to the lamp assembly and replace the bulbs.  My thinking was that since my two front locks were opening but no others and my keyless remotes are working, it has to be a fuse or relay that is not working!  So, I talked with a NAPA rep and he said the "Day running lights" relay can be a temporary fix to get the rear locks open to replace the bulbs.  I looked up in the owners manual where both relay's are located and removed the "Locked" relay and "Day running lights" relay and put the "Day running lights" into the same slot where the "Locked" relay was not operating and it worked!  I got the doors unlocked and replaced my stoplight bubs replaced.  Now, I have a new problem, my Tahoe won't start!!  I'm assuming the relay wasn't supposed to stay in the wrong slot when operating the vehicle because I started the truck, and it started and died-started and died-same and again.  I think the wrong fuse can be used to fix another problem like a fuse.  But, a fuse you can leave in and deal with one operation in the vehicle not working until you can replace the fuse later when you purchase it.  But, not a relay!  Now, I think the confused electronics cause another component (possibly the fuel pump relay) to burn out with the wrong relay in place of another when the vehicle operates.  I should have known but I was so glad to get the doors open after two months and it being Memorial Day weekend.  Now I have to find out what else is wrong so don't make that mistake to avoid the same predicament.  Better to get the relay ordered and replaced than to have this happen to you.

SOURCE: Back hatch will not unlock/open

you could use some lithium grease and spray it in the general area of the latch and hope it lubes the latch enough to loosen it to open. but it will cause a mess spraying it

SOURCE: power locks for rear doors and hatch not unlocking

you have two relays on the interior fuse block one for locking and one for unlocking. Swap them and see if the problem is now such that they will not lock. If so you have your answer.

How do you open the back door (no manual)


Rear hatch is locked or unlocked with a key. (if equipped) • To open the rear hatch, insert the key into the lock, turn it to the unlock position and pull up the rear hatch by pressing the handle (DOOR). You can also lock/unlock the latch (but not release it) with the central door lock system. • If unlocked, the rear hatch can be opened by pressing the handle (DOOR) and pulling the hatch up. • To close the rear hatch, lower and push down the rear hatch firmly. Make sure that the rear hatch is securely latched.

Since the driver's door gets the most use, and all circuits run through the master switch, check driver's door first and check the wiring at the hinge area for breaks.

Used the key to unlock door and alarm started going off. put key in ignition to start, but wouldn't. removed battery cable, do to neighbors, and the alarm keeps sounding. how can I shut it off? just...


With the drivers window down, and the doors closed. and locked connect the battery and lock and unlock the tailgate with the key, you need to unlock it twice to unlock the doors and turn off the alarm. If the locks are working like thier supposed to the drivers door will be unlocked and opening it won't set off the alarm. the truck should be back to normal. If not disconnect the battery again. Drivers window down. Put the key in the switch and turn the key on to the run position. With all the doors closed connect the battery. connect it good and don't bounce it around. If the battery casbles aren't clean clean them good so it'll connect good. If it still is alarming then the doors switches are likly. Or the door locking motors. You should be able to lock all the doors ( including the hatch) by hand and get the system to reset. Try it all again using a different door to double unlock as a lock switch might be sticking. If the system can't verify that all the doors are closed and locked it won't reset. If you connect the battery wihg the key turned on the system thinks it's already running and appeares to be in the unset mode.

Did these doors quit at the same time or over a period. It seems that the actuators for the locks have gone bad. With the mentioned doors, that's a lot weight for the actuators to unlock and pop open. With the remotes and console not working , that's more reason to think the actuators are the problem.

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.

Battery died now power sliding doors and rear hatch not operating


1) Unlock all doors from driver's door while it is open. The driver's door is the only door to remain open during this process! 2) Turn the key from OFF to RUN 8 times within 10 seconds, with the eighth turn ending in RUN. All the doors will lock and unlock if program is successful. 3) Turn key OFF and remove key from ignition. Within 20 seconds, press any button on the remote. (Press sliding door or rear hatch and it will open!) 4) If door locks do not respond, wait several seconds and press button again. If doors still fail to respond, try repeating steps (1-3).
