Rear Window Defogger

I recently got a 95 Wrangler. The rear defogger doesn't work, but the fuse is fine. Does anyone know what is in the circuit? I know there is obviously the switch and light bulb for the switch, and I know where it connects to the fuse panel. Am I missing anything?

I had a similar problem with my hard top. It turned out that the electrical connections that run thru and connect on the ends of the door/window shocks were not making a good connection. After I cleaned the spade style connections(all 4) the heating elements worked fine. It may not be your problem but it may be worth looking at.

I believe there is also a timer/relay near the fuse panel for it. I think it's red? Does the light on the switch come on? Do you get 12v to the wires coming out of the hardtop? Is the hardtop plugged in? Is there power at the plug that plugs into the hardtop? Does the hardtop rear light work?

Thanks folks- Yes the rear light works, so I'm guessing the hard top is plugged in (the windshield wiper also works). The light goes on on the defogger switch, and I believe the relay works because the light on the switch turns off after 10 minutes. So I'm assuming I need to look at the connections or the wires going from the fuse box.

Put a test light (or voltmeter) in the connection...
