I had some body work done on my car a few years back which required the back window be removed. When they installed it, the rear defroster no longer worked. It's long past their warranty date, which is my fault because I never took it back in. Can someone tell me where to look at where it should be connected? I've looked, but I don't see any wires or connections of any kind. I'm sure I'm not looking in the right place...

Thanks!
