I am not sure if this will work but you can call you local dealer and see if they have this part in stock.
It is about $2.85 and it may work.
It is for a convertable back window. They tend to break the connector/terminal on them.
For as cheap as it is it may be worth it since a new tinted window is $770.
If it's the little metal tab that should be stuck to the window, then you can pickup a rear window defroster kit at the parts store. They come with stuff needed to reattach the tab, as well as fix one of the gridlines if it ever gets scratched. Usually runs $5-$10 for the kit, I usually keep one around just in case.
