rear hatch lock doesn't work at all now. it used to lock and not unlock and we had to crawl into the back to unlock it. it has randomly not worked for years but not it just won't lock at all any more

tailgate either locks and won't unlock or doesn't lock at all. rear defroster works intermittently and the windshield wiper and washer fluid works sometimes too....has happened since I owned the vehicle for the past 9 years

my 2004 gmc envoy xuv v8 . had a roof and end gate problem .. the computer for the roof was detecting the end gate was open so nothing was working proper ,,the hinge on the door was sending a false signal so my roof was open ,could not close it had to go to the dealer and paid 2200 $ and change everything possible .. and at the end realized that the hinge of 100 $ was the problem .....

The plastic panel across the top popped out of place. I cant open the back (glass or entire back hatch) at all! In effect, I am trunkless! This was not a result of any kind fault on my part. It was normal wear and tear. I have been told it is a design flaw- water seepes in and ruins the latches. It usually happens during the winter when water gets in and freezes. They see it all the time supposedly!!!!
