Can anyone offer any advice. The heated rear window on our 2007 9-5 saloon is not working, but the heated door mirrors are working fine. Therefore, the relay must be fine, and the light comes on when you press the switch. I have also replaced the 40 amp fuse so that is fine as well. I have heard a couple of stories online that people have had loose connections at the rear window, but that problems can also arise from the radio antenna on the roof of the car? Anyway, if anyone has any advice, it would be much appreciated. Thanks!
