The door locks on my Expy are going crazy. Locking and unlocking automatically. Sometimes several times in a row, sometimes only once. It is a continual problem which occurs even when the vehicle is shut off. At dealership now - they have replaced some computer module which controls all the accessories, but problem persists. Dealership cannot figure out the the cause. Any suggestions.

 

Did they check the actual switches on the doors? Maybe one of them is shorting intermittently.

Just a thought....
