Rear window defogger

djd71355 · 10-04-2007, 04:42 PM

I have a 2003 Alero. The rear window defogger will not work. I replaced the fuse and the relay. Still nothing. When I push the defogger button the light goes on but no action in the back. Any ideas?

Use a volt Ohm metet to test the GRID the lines running .If scrached or broken .They make a repair kit

There is a modulator in the C pillar that goes bad.

It's a PIA to fix and you can only get it at the dealer avg price $140
