Gmc Envoy Rear Hatch Problems. The 2004 gmc envoy has 4 problems reported for tailgate issues. When this happens, i can’t get the rear hatch open unless i pop it the manual way via screwdriver.
So after googling the issue, it looks like it could be the liftgate module or rear hatch module which On june 3, 2008 the contact had the rear end gate controller, the lower end gate hatch accelerator and the left upper hatch accelerator repaired, and the failure had returned. I was dropping my boat off at the local storage yard where i keep it.
