1993 525i - power locks unlocking themselves

Just picked up a 1993 525i in great shape, but a few things slipped by my
inspection. Most importantly, the locks have a tendancy to unlock
themselves. If I lock them while I'm in the car, they may immediately pop
back up, or they might pop up some minutes later. Sometimes they'll go up
and down a couple times in quick succession. Once up (unless they
immediately go back down), they stay up. This has happened a few times
after I left the car as well, i.e. returned to find it completely unlocked.

Seems like a short somewhere to me, but thought I'd try this group out
before trying the more expensive and time consuming solutions. Thanks for
any help!

Check the central unlock switch first. It's in a prime position to get
gummed up and not release once pressed.

1-If the problem happens only when you lock with the remote, the "open"
button might be the culprit.
2-If it happens even when you lock with the key, you'll need to check that
other circuits are not faulty. IE-if there is a door ajar, the system will
lock then pop the lock open. The door may be closed, but if the sensor for
that door is faulty you will experience exactly what you have described. You
can check by making sure all the doors are closed, then open one and
manually depress the pressure switch and try to lock. If you find one that
causes the problem even when you manually depress it that's the bugger. Of
course, if none of the sensors replicates the problem you will have to
visually inspect to see if perhaps the door is not closing enough to depress
the sensor.

Good luck.
