Rear Defrost stopped working
I am hoping someone can guide me to what may have caused my rear defrost to stop working. 1996 Taurus GL wagon 3.0 liter Vulcan 175,000 miles. I am the original owner of this car and have managed to keep it in good repair. In fact this is the only thing that does not work. Last year it stopped working in late Fall. I cleaned the negative clip (right side) on the windshield as I had noticed some corosion---from there it worked all winter. A similiar clean this year did nothing. I changed out the relay with a new one. Both fuses look fine. The light goes on when the button is pushed, I hear a click, and it will turn itself off after 10-15 minutes. I can get no sign of current using a voltage tester on the clips or the harnesses attached to them. Could the switch/timer be bad even though the button lights up and times out? Is the switch/timer one unit on this vehicle?
Any help or advice would be greatly appreciated.
