I took out my AC and now my fan runs constantly and won't turn off. It only comes on when the engine is running... the key can be "ON," but if the engine isn't running the fan won't turn on -- kinda weird. I saw a post by Vader regarding a connector that needs shorted but I don't know which connector that is. I've already tried the one on the passenger side of the car with the blue and black wires, but that didn't work. Thoughts?

 

You need to have a jumper between the light blue and black/white wire to complete that circuit. Having the circuit open will operate the fan at any time the engien is running, as you describe.

The pressure switch at the compressor should not require any special connections.

 

Vader, where is that connector located on the car? I reviewed the wiring diagrams for the fan circuit and the air conditioning circuit and the only thing I've found is the connector with a dark blue and black wire. That's the same one that I tried with no luck.

 

Fixed it. I was shorting the proper wires, but the connector going to the ECM was loose. I reseated it and it works now. Weird.
