I have a 1988 mustang gt hatchback and the rear defroster is having problems. When i push the defroster button, the light comes on and only a few of the lines in the back work. Is there a way to get a new defroster "grid" to put back there or do i need a new window?

theres a kit u can buy at part stores.

uoi find the break in your line, apply this paste, with masking tape around the edges, allow it to dry, peel up tape, and good as new. i used it before it works good!

That kit definitely works, you do have to probe the lines individually to find exactly where the breaks are, and then apply the repair.
