Hy. Sorry to open yet another SAM thread, but I got them both replaced with exactly the same reference and to no avail.
Car is a 2001 C 180 CL203 VIN WDB2037351A122738 engine code M 111.951.
Like stated in the title wipers do not work - at all, i got no interior lights, AA/C command panel is dead (no lighting, no response), SRS indicator is ON(probably because of the ESP codes). There's the "display faulty" warning.
Fuses/relays have been checked- all ok. Battery is new and fully charged.There was a battery drain before (i will have to wait to see if it's still there) - car does not have power seats.
Everything else seems ok (lights, indicators, engine, etc)

Here are the codes I pulled from it :
