Hi everyone,

I have a 2000 Chevy Cavalier, and my rear window defogger has stop working. I purchased a new relay and want to swap it. I thought it was under the hood in that box - its not - does anyone know where it is located?

Thanks
Marykay

 

mks, I have looked in our parts catalog and service manual and cannot find a relay for the rear defogger. I think it is controlled by the A/C control head.

Kenl is correct. The relay is an integral part of the heater control unit.
A couple things you can check are the fuses at the i\p fuse box....one lebelled RR Defog and another labelled HVAC.
Does the light come on when you press the button?
