BMW Repair: Door Lock problem on 94 318ic, micro switches, passenger doors


Question
Doorlocks on 94 318ic lock without warning on their own.  Doorlock Remote control stopped working as well. (i replaced battery on remote so key chain remote is not problem)

Doorlock issue can happen when driving or parked with the engine turned off.  Many times, when i try to unlock from inside the car, the locks lock down right away. Problem is progressively worse.  First noticed problem while driving and hitting a bump.(locks locked on own)  Problem seemed to increase during rain but problem is increasing now with no rain present.   Windows now go up and down in conjuction with doors locking on own.

Any solutions would be appreciated.

Answer
Check all the micro switches in the drivers and passenger doors.  If these are OK than suspect a poor alarm installation or a door lock modeule.  Start by searching for a bad microswitch or door switch.
let me know what you find out.
