my car has had dew on the rear windshield for the past 2 mornings on the way to work. So I turn on the rear the rear defroser the button LED illuminates but the defroster is not working at all!
I turned it on for 40 minutes turning it on again when it switched itself off but when i touched the rear windshield it it was cold. I have read there is a relay and fuse under the rear seat, I am confused that the switch LED came on though. Are these likely to be the only things that i should check?
