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.

Try the Driver Door Module fuse 15A

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

With regards to the lock bittons on the driver and passenger side its the button themselves aka switch(s) that is your culprit. Why because the remote is getting the motor to open and close them . The only thing that doesn't is the buttons /switches themselves .
Now the rear latch a little different animal. Either the locking mechanism on the door itself is defective or the motor ( the thing you hear clicking) is weak.
This one your gonna need a shop manual for to do the correct testing.But being that te remote will not move it and neither will the manual push button I would lean towards the locking mechanism on the hatch/door its self. Use the shop manual its not that bad of a fix if you have a little patience.

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...

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.

check the clamp sensor front and back door

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. 

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.
