Noticed today on my son's 2005 ZR2 blazer, the key fob will cycle the doors locks and if you use the door lock switch on the door arm rest area but it won't fully lock the drivers door. It will Lock the passenger door and will unlock both of them, just only gets the latch half way down on the drivers doors.

The rear latch will open as long as you either have somebody open the latch while you are pushing the dash mounted switch or if you hit the key fob while pulling up on the latch on the glass? Do you think that could be the supports are shot and its too much weight for the glass to release itself?
Thanks
