Hey folks, a question for you techies. On my 99 cavalier the rear defroster doesn't work at all. Here's what I checked:
1) The fuse is fine, good voltage on either side. 2) I took the guts out behind the "on/off" button and checked for continuity when the switch was in the on position. That checked out ok. 3) Went to the back window with my multimeter and had the leads on the multimeter touching both plugs on either side of the window. No voltage at all.So, either I'm testing something wrong, or there is a break in the wiring between the switch on the dash and the back window. My haynes manual has no detailed wiring diagram of the defroster, and I'm at a complete loss.
Is there something else I should check? Am I forgetting a mystery relay somewhere?
TIA! Sparky
