basiclly my heated rear screen don't work in my s2. You can press the buttom which lights up and goes out afterwards but it does not clear any lines at all.

is there a way to test for power at the back?

I'm not to sure how to check it on my car.

cheers folks

 

if the light comes on you will have power...your screen will be fooked...try a continuity test on the glass via both terminals..chances are the glass is the original and just "broke" like other car parts

 

i have 2 contacts on the screen is one positive and the other negative?

 

yeah...iirc the n/s is an earth thats just screwed to tailgate and the o/s is the live..

 

I had same problem with mine,check the wires are in tacked in the rubber gromet that has the wires in on tailgate(top corner) as mine had snap.

 

cheers mate, i'll try that cos when i checked the power at the screen with switch on, it gives nothing

 

Pretty confident it will be broken wires between the body and the tailgate.
