my buick rendezvous door locks have begun locking and unlocking themselves
while i'm driving. it seems to happen after driving for awhile - not just
short trips. the locks begin switching slowly and then they get faster and
faster. after doing this the other night the locks themselves stopped
switching to open and closed, they remained locked and there was a clicking
sound low/center of the dash. any ideas what could be causing this? thanks
for any help you can provide. our dealer has no idea.
