Back lift gate/glass would not open or release. Even when unlocked with the key fob or the unlock switch on the drivers/passenger door. ... How To Install Replace Rear Lift Gate handle 2002-09 GMC Envoy Chevy Trailblazer ...

sounds like something may be shorted in your rear hatch switch and when you pushed the button to open it you may have blown a fuse. I would check your fuse and make sure they are all still good. I would also try to look inside the rear hatch and check the wires and see if there is something wrong with one of them.

I found this URL on internet http://www.chefseattle.com/blog/site-news/suburban-rear-liftgate-wont-unlock-how-to-fix/ It might fix your problem.

I've had the exact opposite issue with my 2005 Equinox.
My rear door is locked and will not unlock.

my 06 tahoe just got this problem...all other doors lock and unlock with the fab and door switch...but the hatch is in permanent locked mode. i cant even unlock the hatch window. why is this happening?

check wiring on passengers side near the rear hatch speaker, the rear door speakers are run through them also. i had the same problem and it was a unplugged connector at that location

Hello Scullen27,

While I vigorously recommend owners wanting to work on their own vehicles should purchase the FACTORY WORKSHOP MANUALS... for one time little jobs there are a FEW good alternatives... that ae also FREE.

BBB Industries maintains an very excellent technical database
for popular USA market vehicles:
TECHNICAL SERVICE BULLETINS
and Circuit wiring diagrams
(registration is required... as these are real documents)

A fuse would seem to be indicated ... if your
control is sound a relay operation... but the
REAR-HATCH is not cooperating... THAT WOULD
be the place to start,

Hope this helps...

check the clamp sensor front and back door

Sounds like bad wiring, or bad door lock actuators. Check for power while locking/unlocking the doors.

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.
