The fan will run whenever the compressor is engaged. If the AC ECU decides that it is not happy and it shuts off the compressor the fan will also shut off (if it doesn't need to be on for the coolant).

So just to make sure I am understanding you correctly, the fan doesn't necessarily need to be on anytime the AC is working properly only when the compressor is actually compressing?

How do I check a pressure transducer? How would I know if mine was bad?

Thanks for getting back to me so quickly!
