Hi guys any one have any ideas I have merc c220 d and the rear windscreen heater stopped working, checked fuse ok, checked the screen wire and tested the circuit all ok , changed the relay , no change is there something iv missed?
If you have power at one side of the screen and earth at the other then it should work- The connectors sometimes detach from the glass or become loose and give a bad connection, can be made good with electrocure paint
