Update:1994 960 sedan, central lock system locks and unlocks all doors and trunk at random periodically on its own while driving or at a stoplight, and one time while parked along the side of the road with the engine running with me out of the car.

I posted on here sometime ago and was told to replace the central locking relay. I found the relay location and replaced it on Thursday. See pictures below in the next message I posted. It turns out after driving for a couple of days that there is no difference. The problem is still the same. Very intermittent only does it maybe once or twice while driving for a total of a couple of hours altogether during the course of the day. Might not do it at all or more likely might do it once then I manually reach for the **** and unlock the doors, then it might do it again in a few seconds or 30 minutes later if still driving or not at all. This makes the prospect of recreating the problem and fixing it difficult.

Anyone else experienced this and figured out how to fix it or what other areas to check? I can wiggle the lock **** on the driver's side door pretty seriously and it never triggers the system to lock the doors, unless of course I push down on the **** which it should lock. And as mentioned a long time ago in a previous thread about this problem, sometimes the locks will UNLOCK themselves if I leave it alone, a few seconds or a minute or more after the locks automatically lock themselves. I usually don't wait to see if it will unlock, I just immediately reach back and pull the **** to unlock the doors.

Open to any additional suggestions for troubleshooting.

 

I got the cover removed and replaced relay C in the attached pictures which show the location of the relay panel.
