Rear Defrost

Just noticed the rear defrost dosent work on the impala,tracked the problem down to the wire connector on the rear glass has been pulled off.Now I was wondering what I could use to reconnect it back to the glass,thought about soldering it but I'm affraid the glass will break with the heat of the gun.Anybody know of something good to use to get it back on?Is JB weld conductive?

Myself, I've had poor results with fixing this, I would try a glass shop, there are some industrial products that can work at times.

Most parts store have a product made by permatex to fix your issue
