Heated screen

[def843t]

My heated screen does not appear to work, fuse is OK and warning light comes on. Where is the problem likely to be ?

Cheers.

First question: how do you know the screen isn't working? How are you testing it?

 

Assuming it isn't working, if the fuse (No 4, 10Amp) is OK and the warning light comes on, it's either a bad connection to the heated screen itself or a faulty switch. There is a green/pink wire which carries the +12v switched by the ignition to the screen and a black wire which connects the other side of the screen to earth. You really need to use a meter to check you have continuity between these two wires, but failing that a test light and a 9v battery will do.

 

If that checks out OK, the switch must be faulty. Even though the light comes on, the light is on a different set of contacts. Pull the green/pink wire off the switch and connect it to the green wire on the switch by touching them together. If this makes the screen work, then the switch is kaput.

 

Hope this helps
