We discovered last winter that one of the "clips" on the rear window has come off thus rendering the entire rear defroster unable to work. We tried several things -- electrical tape, air conditioning tape. Our next step is cold solder. Has anyone ever fixed one of these? Talked to my mechanic and he was at a loss too. I don't want to put a lot of money into it -- but would like to know if anyone has any ideas. Thanks! :sunglasse
