Central lock system

Help!!!

1987 325, 2 door. When I try to lock the doors with the master key in the driver's door, the doors will not lock. I heard a little noise like it's trying to make an electrical contact. Noise seem to come from door hinge area, either door itself or kick panel (driver's side). When I try to lock door from the trunk's lock same thing. Any ideas?

Thanks in advance.

Sounds like a door lock motor or Central lock control is bad. I just replaced both on my 1990 325ic (bought use from Bavarian in CA). Go to:
