Thanks for your reply...

On the issue of which sensor is broken, I have attached a picture of the receiver drier to this message. I believe the one that's broken is the one on top - that one isn't inside the system right? So that's the temperature switch that turns on the auxillary fan.

The reason why I want to wire the auxillary fan to come on every time the compressor is on is because prior to the accident, I hadn't seen my fan come on even in the hot summer months. Furthermore, the temperature of the air from my vents just creep up and up while idling like at a traffic light. I read from another forum member that the auxillary fan which wasn't coming on was the cause of that increase in temperature.

What you described as a "clever" way to do it seems like a much longer story than what I've read from people here before. Unless I guess, the simple way would involve by passing the temperature sensor on the receiver drier. Well I hope someone here who has done it replies so I can read how they did their specifically.
