92 Sc3-I'm working on getting my defrost to work even though we have beautiful weather in Florida, I need to have FULL workablity in my car. I'm not clear on where the plug in for the defrost is located, in the trunk or under the rear covers where the speakers are located.. I dont have a manual, and google hasnt helped much. But I've read post about cracked or broken prongs. Where's it connect?

Also,I've changed the relay and this one gets hot but no go. My heat does work but doesn't melt me like I think it should. I don't feel heat on the fins on the rear window. There's o.e.m tint and no visible cuts.

Any fuses or anything particular supposed to checked?

A step-by-step guide to how to check the ac codes might help.Thanks CL.

 

Well the defrost plugs from the wires to the window are located under the rear window molding. I can't remember which side at the moment, but removal is fairly easy. Just take out the rear seat (pull up on the top portion and then unbolt the bottom portion), pull off the rear bottom side molding and then unscrew the window molding and you should see the connections on the side of the rear window.

 

I appreciate that FutureSc! I will get on it in the am.

 

So recently I found out my redefrost wasnt working, pulled everything out to test the electrodes that connect the wires on the rear windshield. I got the top 2 reading the 12 v and have ground on the bottom. The question is should i get new glass or break it down and find the wire feeds that glue to the window? If anyone has insight it would be greatly noted. Has anyone went threw this?
