98 rear window defogger not working?

[cd4th]

The rear defogger stopped working in my 98 PA. The light on the dash switch still lights up so I must be getting power that far. Is there a fuse or relay somewhere between the switch and the window I could check or replace? Any known problems with these? I really hate electrical troubleshooting. Thanks.

"rear defogger"?

Is this a fan motor or an electrical grid built into the window?

Either way, take a voltmeter or test light to the connections AT the device and see if your getting power that far. I believe the rear defrost has it's own fuse in the fuse box.

The relay and fuse are located under passenger side dash and should look similar to the one in the link below;

Thanks. I'll have a look at things tomorrow. Does anyone know if there are any wiring diagrams available online somewhere. Have some other things I need to track down also.
