Guys,
Does anyone know how I can check that this works as it should, been looking through some threads on this and I am not sure I have had this fitted when I had a replacement window fitted a year ago? The button lights up but the revs don't move and I cant find any inkling of heat coming from the window.
I have to admit I never even used this before I had the window out, just gauging how I can tell if its actually working, or not!
The side mirrors heat up as they should.
