Re: 93 900 TC Rear Window Defroster Posted by DivrDon [Email] ![]() ![]() In Reply to: 93 900 TC Rear Window Defroster, Paul Rinaldi, Thu, 28 Dec 2006 07:13:45 Members do not see ads below this line. - Help Keep This Site Online - Signup |
There is a mercury switch on the top's frame just behind the liner driver's side rear. It prevents the defroster from working when the top is down. Check power through the switch. Check voltage and continuity to and through the window grid. I'll be watching this post since I have the same problem with my '87TC but haven't had time to work through it. Last time I used the car in the winter (4 years ago) it was an intermittent problem and I changed out the switch and relay. No help. Now the defroster doesn't stay on at all, like yours.
