In Reply to: Door Locks, need help posted by Bob Sabo on January 08, 2000 at 12:50:53:
: I have a 90 525i, driver's side door lock does not work from outside car while trying to unlock. When key is inserted into door and turned to the unlock position, I hear all doors click, but doors do not unlock. I do the same on the passenger side, and the locks open for 1 sec. and goes back to lock position again. In order to enter the car after locked:
I think that Tim C. suggested trying a lock reset.
You should probably also check the fuses for the power locking system. There is one in the engine bay fuse box and another in the fuse block under the back seat.
I had a problem like this and tracked it down to the fuse under the seat. In that fuse block there are a few fuses that are not covered, and I recall it was one of those. ('91 535i)
I gather that the locking system monitors the drivers door and the boot locks to test for lock/unlock states. Problems in either of these locations will confuse the lock system.
OTherwise, BMW have told me that screwy things can occur if the battery is on the way out.
