Rear access code

escallade1

I'm having a problem with my rear access code message on my truck while I'm driving it. The code comes on, the dome light comes on and the locks chime. I've take it to the dealership several times and I'm still having the same issue. Please HELP!!

Tricky. Could be any number of things----Body Control Module, Rear Glass Actuator, Tailgate Lift Actuator etc. You might double check that the rear glass is properly closed (if you have a lift glass).

Not sure why the dealer can't pin this down.
