The car is a December 1995 W202. The side mirrors does not retract automatically, it folds via pressing a button. Anyway I was able to resolve the problem last night. Like MBDOC's response to another post regarding a 140side mirror problem, I dismounted both side mirrors and noticed that almost all the wires were bare. The insulation basically crumbled and the wires were touching each other causing the short. I rewired both side mirrors and now everything is working as it should be. BTW, I really do live in Rome ! Grazie !
