I know that this is a Bonneville forum, But this is probably the best place to get this question answered. Since you guys have been so much help to me on my 96 bonneville.....
My daughter either pulled it off or it possibly could have just fallen off, But I doubt it just falling off........
The rear window defrost feed, had been pulled off or just fell off, like I said earlier, probably had some help, (by my daughter) lol.....
Anyways, how or what do I put on it to reattach it?
Thanks for your help.

Your talking about the switch? You may have to pull that part of the dash and put the switch back. If it'* broken you can use some JB weld to attach it.

solder!

No, it is not the switch in the dash, it is the wire that hooks to the back glass and puts electric to the window.
I see where it was hooked to the window, but not sure what is holding it to the window, It is black, but doesnt look like solder
