My elec door locks have taken on a life of their own. When I use my remote - or the locking mechanism on the door - they frequently begin a pattern of "lock-unlock-lock-unlock-lock-unlock for up to almost a minute.....and I can hear a humming/mild whiningsound coming from the sliding door area on the driver's side. This happens even when the car is already in motion and it performs the system lock at about 20 mph. At this point, my driver's side door lock button will no longer go up and down but we can lock everything else manually except the tailgate. Any ideas?

 

possible one of the switches is stuck electrically and telling the computer to keep locking and unlocking it to figure out which one U will need a dealer to get into the body computer.
