Hey guys, new to the forum (and MB), but have done plenty of searching. Here's the issue with my new '95 C36, I'd welcome some suggestions. Remember, being the C36 these are the sport seats.

Passenger seat: doesn't move up/down on either adjustment, backrest doesn't tilt forwards. All other functions work, including backrest tilting backwards.
Driver's seat: backrest doesn't tilt forwards or backwards, all other functions work.

I've cleaned the switch, then checked for voltage at the seat wire harness plug. When I activate the seat switch, even the functions that don't operate, I can find 12V at the harness. All fuses check out good.

So, it appears my problem is either between the plug and motor, or with the motor itself. I can't hear the motor attempt to operate, so I don't think it's a stripped drive mechanism. However, one of the backrest motors will recline, but wont move forward.

Suggestions? My current plan of action is to remove the seat and test for voltage at each motor. I've read of issues with the relay, but that normally disables all seat functions. Plus, I have power at the seat, so I can't see how it's a relay issue. Probably unrelated, but my left side power mirror is also not working. Driver's side works well. Oh, the joy of German cars.
