    I have a 2007 Prius and the rear defroster no longer works. I took it to Toyota and they said the connector has come off and needs to be put back on or the window needs to be replaced. They do not fix windows.

    I thought I would try this kit 1st and see if I could fix it myself.
    Permatex 21351 Electrically Conductive Rear Window Defogger Tab Adhesive



    I need to know how to get access to this connector. Where is it located? Do I simply pull off the side panels at the rear window? Is there one that needs to come off 1st? Any tools needed?

    Thanks very much, Kent

    I bet it's pretty visible and accessible once the hatch inside trim is pulled off. I've pulled off the hatch inside lower trim on a gen 2 (easily), the part that's behind the garnish piece that always breaks. But I don't remember if that was one piece for the whole inside of the hatch, or if other piece(s) go up the sides of the window.

    I suppose the tab adhesive might do the trick, looks like that's exactly what it's made for.

    I haven't ever reattached a tab. I did fix one or two rear defoggers with the silver paint for fixing where something scratched through one of the traces.

Don't mess w glass clean pads take atom cement popsicle stick onto pad area on glass a dab on pads wait 25 or seconds apply pads of tang to glass hold a few seconds . Let stand overnight Before attempting to add wire connector done . Atom cement. Is the standard
