cliffcoggin Posted January 5, 2021 Share Posted January 5, 2021 Naeem. I know nothing about your particular car, but I can say that there bound to be a relay somewhere. The current used by demisters is too high to be handled by a dashboard switch alone. Quote Link to comment Share on other sites More sharing options...
uk174 Posted January 5, 2021 Author Share Posted January 5, 2021 thats exactly what we thought judging by the size of the wire supplying the switch unit, but I am at a loss as to location. thank you Quote Link to comment Share on other sites More sharing options...
Magnet Posted January 5, 2021 Share Posted January 5, 2021 Hello Naeem, Do you have an owner’s handbook for the car? If so, the relay position ( if fitted) is usually shown within the section dealing with fuses. Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
