Just replaced the resistor for the heat. Now it works on the "1,2, and 3" settings..however, NO heat from the #4 setting. I know that it is controlled by a seperate circut, but where do I look for it?

THANKS A BUNCH...

 

Sounds like the fan speed switch. I had an Altima that would only blow air on the "4" setting, that turned out to be the switch. That's my $.02.

 

so where do i look?
