Thanks for the tip. I'll go ahead and replace the CT Sensor as soon as I find one.

At least I know that the fans work. Since my car does not reach the 107+ temperature range too often, I was not sure if that sensor was working. But since I did the "resistor" trick, they do come on. Again, I'll still replace the CT Sensor as it is turning within the base.

So now I need to find out why fans don't come on when the air conditioner is on and running for a while. I just had the Expansion Valve and Receiver/dryer replaced and then a vac and fill. Finally, cool air!

There seems to be 2 sensors on the Receiver/dryer. I'm wondering which one of the 2 controls the aux fans and how to test to make sure that the wiring and sensor is ok. Any idea?

Thanks

Willy
