The rear window and driver side mirror defrosters have never not worked properly, the passenger side mirror works fine. This has been taken to the dealer 4+ times and they say it's showing that power is getting to the windows defrosters, so it's working fine. I have to have a towel in the car at all times to wipe down the inside and outside of the back window, and the side view mirror. They are never clear. The passenger side mirror....fine. ????? The dealer service department has done nothing to help us. I assume this will be a very expensive repair, which is why they are waiting us out.
