Hello! First timer here....

Just bought a 1999 230c Kompressor, got in this morning and put on the rear defroster...light on switch went on but defroster didn't work. Any ideas? Thanks

 

maybe there's no supply to ur rear defroster due to the loss wire connectors or other wiring damage...
if not there's a open circuit in the rear defroster itself and in order to change it u'll have to change it together with ur rear windshield which is costly..it cannot be repaired

 

the "supply" i meant was current/voltage supply...

 

yikes.....thanks =)
