Door locks lock and unlock on their own and set off alarm.

While driving, my locks lock and unlock on their own constantly. Sometimes when you shut the door, doesnt matter which one, all the doors lock on their own too. And sometimes, when you go to get into the car, unlock the doors and get in to start the car, it wont let you start it and the alarm starts going off. I have to either keep taking the fuse out or just leave it out. Any advise will help.

Can't offer any advise yet, but my Volvo 850 has just started doing a similar thing - that's why I'm looking here for advice. When I try to lock the doors with the central locking, they immediately unlock again. Like you, the only way I have found to stop this so far is to take the fuse out!! If I find anything on another site, or in my attempts to fix it, I'll let you know.
Good luck
Stuart
