I have a 1987 325I bmw and the electric door locks do not work. The driver side door works and the trunk will open. Any ideas?

I had ths problem and it was the central lock contriol module (located behind drivers side kick panel and below the speaker) I replaced both the module and the drivers side lock solenoid (about $100 total used from Bavarian auto parts in Sacramento CA) and all locks work correctly.

Did you try using the “search this thread” in the BMW site for door locks? You might read problems and answers that help. I read a few that might fix your door lock problem. I failed to tell you about the search this thread part. Sorry Dave
