1998 C-230 -front windows and adjustable mirror switches stopped working. checked fuses # 7,8, and #3 in the trunck, all good. We replaced window switch cluster thinking it may be the problem. Same problem exsists, back windows work fine, power seats work OK. Just no front windows or mirror adjustment. Any suggestions? Does anyone know if there is a related relay?

 

possibly a bad door control module...

 

Hi I have a c200 with the same problem and would appreciate any help on the subject.
How could I confirm a door module????
