3.4 to LT1 swap, need A/C help

The compressor won't kick on. I'm still using the V6 fan. Is the PCM looking for another fan before it will turn the compressor on?

Did you wire in another relay and circuit for the other fan? I was looking at a wiring diagram and the PCM has two fan circuit inputs and outputs.

I swapped the entire harness, actually both of them, engine and body harness in the engine compartment. A/C worked great for years...

That's probably where my problem is. The PCM must want another fan.
