2002 C230 Wiper problem.
 

Hello.
I have a 2002 C230 and recently I had a problem with my windshield wiper parking at verticle position. I took it to a local garage and they found that my motor was bad. So they replaced the motor and now it won't move at all. The Garage said all they did was unhook the battery, plug in the new motor and hook the battery back up. They did not do any wiring work other than that. Now I have a few extra problems with the car. It Windshield wiper gets no power so it won't move anymore, Cigarette lighter socket isn't powered, My SRS light comes on and the airbag light comes on. We've checked all the fuses and all visible wiring and found no problems. Any idea what might cause this problem? I'd appreciate any suggestions.

Thank you

The wiper and cigar lighter get power from the front SAM. The SRS module may as well, but don't take my word, I'd have to look that up.
Not trying to sound mean, but if they can't fix a simple wiper problem then take it to a better shop. That vehicle should be at a shop that specializes in Mercedes Benz. Especially for electrical problems.

Have them check the Circuit 15 relay, (M), as well as fuse 46.

ON the W203 chassis the hood must be closed for wipers to work...possibly a problem with that switch???
