I had one fall off in the middle of winter and went to pepboys and bought a kit designed to fix such a thing. it uses a liquid silver solder and was < $25
It fell off the window after using the kit (prob due to the cold weather =/ )so I took it to the dealer. It was < $100 to fix the window and it was winter and I needed to see so I went ahead and did it there.
Been almost a year since the dealer fixed it and its been fine since.
heres a site that has it for $28 but look around at a parts store and see what you can find
