Rear wiper and defrost not working

I have a 2005 4Runner and for some reason my rear wiper and defrost have stopped working, as well as the defrost for the side mirrors. Does anyone know of a fix?

I should mention, the back window doesn’t roll down or up seeing as there’s a dent in the hatchback so I don’t think it could be from that. I do remember having to unplug the battery before this started happening. TIA!
