Rear window defog

**SSMichael** · 07-19-2009, 04:14 PM

Went to turn on the rear window defog last night....nothing...Fuse is good, connections on rear window are good. I push the button in and nothing no light and no defog. Anyone else have this problem? And how did you solve it?
A new switch or relay and how hard is it to change? Thanks in advance..

Supposed to be a relay behind the dash somewhere. Do your power seats work as well?

Yea, my power seat works great.

The relay usually affects both, my next guess would be the switch and the connection

Thanks Joshiedoom I guess I will have to just start taking things apart.

If you need a diagram hit me up.

Dont forget to check all the fuses and small stuff first if you havent!

I will double check all that. Have you changed one?

Switch should be pop in out. I have an issue where I use my defog a lot in the winter and it kills the relay. It also kills the power seats. The relay for those two items are linked together. Thanks GM

I do believe it is in the dash beside the switch. By the time I did anything about the problem it was getting warm and I didnt use the defog. I will look more into it
