2 Questions

Ok ...

1) Where is the thermostat, and how do I get to it?

2) Why won't my AC fan turn on?

Thanks!

A/C fan could be resistor. It's accessed under the hood behind the bolt on panel that goes across the firewall. It's under the windshield wiper/air inlet area. It's the same panel you remove to get at the blower motor. A Bentley repair manual comes in handy. If it doesn't work on the A/C but does on the heater, that usually indicates low freon. If you mean the A/C fan in front of the condensor, there's also a resistor on the motor bracket.

I had the same issue with my aux fan - also used for the a/c.

I replaced the resistor (part # 5) and the problem was corrected.

Hope this helps,
