I recently bought a used Suburban and now the rear wiper and defroster are not working. Fuses are ok. It appears to be a short in the connection from the body to the rear hatch. I pulled the rubber boot off the wires where they come out of the body and there appears to be a burn mark on the blue plastic connector. Is this something that can be fixed at home without going to the dealer? If so, is there a source for the parts needed. Thanks
