Having moved up from ropey bmw to Mercedes E240 Elegance,thought it time to introduce myself and hope to be of use and get plenty use from the forum. should I ask question on here{if not sorry}.Had new EIS switch and Key fitted recently and now find rear wiper not working,no power to switch,have checked all fuses,nothing wrong there,wanted to check relays but don,t know which one to go to or where located.
Any help would be appreciated.
