07 GMC Envoy rear hatch window not locking
Just bought this 07 Envoy and everything is still unfamiliar to me. I don't yet know if this is a problem, but I can't seem to get the window in the rear hatch to lock. (all other doors will lock).The hatch itself will lock with the remote, but the window won't. I shouldn't be able to press the button on the window. If I do press the button to open the window, the hatch will unlock. Is there a sequence to follow that will lock the window? Why bother locking all the other doors when someone can gain access from the unlocked window. I read the manual, but couldn't find anything on this. Any help appreciated.
