Rear window problem

[tattmick]

Anybody heard of this .Last year in Feb.I was driving down the highway,it was about 20deg. outside the rear window was frosted up a little so I turned on the rear window de-froster and about 1 min. later there was a loud POP I pulled over and the entire rear window was shatterd,the only thing that prevented it from coming in the car was the window tint.Anyway when I looked at the plug that connects to the tab on the defroster grid it was melted and the connector thats attached to defroster was destroyed.The company that replaced the window said they had seen that before and that the defroster probably over-temped.Where do I start looking to find the problem and the dealer said you can buy the female connector but not the tab,it's part of the defroster grid.Once I locate the problem can the parts be purchased aftermarket or do I just continue to use my ice-scraper.

If the window was in the 20 degree for a long time (outside in the weather for more the 24hrs straingt) and some how your deforst malfunctioned and heated up the glass very rapidly it can happen. My father works for a Gm body shop and has seen it before, its not common but it does happen.

Yea I think thats what happend,I would just like to know what caused it and see if it can be fixed short of buying a new connector and replacing the window.

I dont know man maybe try and get the parts from a junk yard first?

it could be a bad relay, bad defrost button, or the grid or old glass may have been flawed, or another possibility is the tint that was used could of had some condudctive material in it that caused the grids to short out.
