Door power lock/hatch issue

Hoping someone can help us figure this one out. One day the power door locks were locking and unlocking themselves. Ever since, the power locks do not work (either with the buttons on doors or fob) and every time the truck is shifted into drive the rear hatch unlocks itself. Any thoughts?

:eek7: :wtf: :banghead:

Ha, that must be funny.... The truck must really not want you in there:grinno: . This sounds like you have a short in somthing, and most likely something to do with the Body Control Module(BCM). If its not working right, it can cause funny things to happen. A properly equipped scanner will be able to scan the BCM and see what its doing.
