About 1 week and a half ago my 1990 300e died on me.After diagnosing the
problem it turned out to be a worn out voltage regulator on the alternator.
I fixed the car after about a week in my driveway. Now the central locking
system will not lock the doors, I have to manually lock each door. I think
the fuse is fine because the anti theft system is still working.   The only
thing i remember doing is unlocking the car and locking it a few times when
it wasn`t running. Maybe it is vacuum locked or something..........I also
boosted the car a few times as well and maybe that had something to do with
it.
The locks functioned great before this , so i doubt that i have a vacuum
leak.

any thoughts would be appreciated
