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 ...
the release at the bottom of hatch can be ---rusted normal in northeast --- linkage popped or broken --linkage clip popped or broken --- need to crawl into back and remove the plug [ lower center of rear hatch panel will need a long screw driver and light will see linkage and latch push down on linkage arm and push open hatch when opened you can remove the rear panel and assess the problem but lube the latch and upper window latch
With the doors unlocked, insert a screwdriver into the closed claw portion of the latch. Pull on the hatch door lever or push the button, while applying outward pressure on the claw. It will unlock and work normally again.
Could be the latch mechanism for the door is sticking. You could try using some white grease on the latch and the contact where the latch hooks to. You can purchase the grease from most auto parts stores. You will not need to use alot. Just apply a small amount to the mechanisim and then work it in using the manual handle. Then open and close the door several times to feel the "action". Then apply a little more and repeat. This should loosen the latch and get it working again. Also make sure that none of the tension springs have come loose on the latch. And check the seal around the door and make sure it is not pinched and has a proper fit.
i would say the theft module saw the door trying to be open without the door lock or fob first, once the door lock button was pushed it shut down, it new doors were trying to be unlocked in a theft manner, once shut down it needs time to reset or needs to see ignition cycle with key and read chip in key, smart system isnt it, good luck.
Either the relay for the locks is bad or the fuse. When you push the power lock on the inside if the doors do not unlock then I would check the fuses, both inside and under the hood. If they do work then the relay/s may be bad. You are pushing your key button twice correct?
I have the same problem. This is a faulty actuator switch according to GMC which controls the tailgate and the hatch window. My 2006 has 90,000 miles on it (I purchased new). Warranty is not an option and cost is estimated @ $600.00 in Arizona. As far as I am concerned, it is safety related issue and should be a recall since there isn't a mechanical way to open the tailgate or window as an escape route in the event of failure.
