Hey, I had to pull the interior roofing out of the magna the other day to re-glue the carpet, and in the process i was successful in accidentally ripping both demister connectors from the rear window. Just wondering what the best way to resolve this is???

I used to have a car that had the demister terminal broken off the glass, I asked an Auto electrician to repair it and was told that a special machine is required to heat the glass to make sure the solder join bonds and he didn't have one.
Ask a local auto electrician to see if anyone in your area repairs demisters.
There are also replacement stick on demisters available but they don't look to good fitted over the old one or you can replace the rear window.

I have the same problem. I was replacing the thin ****ty rear dash with a thick MDF for my speakers and when putting it in, i accidently ripped it of the window.

I Havent been bothered to try fix it yet. Im going to see if i can stick it on with blue tack just for now since its getting cold and i will need it.
