Hi, I have a 2007 K1500 Suburban and the other day the liftgate quit working. The hatch glass opens but not the door. It is not a powergate. I am assuming that it is some electronic part inside the door, but don't anyone know how to access the inside of the door to repair it? I tried to find a repair manual for the 2007, but they are not out yet. I was wondering if the 2006 book might work.

Thanks for any help.
