Power fc and AC not working
I haven’t tried swapping back to the stock ecu. But the AC doesn’t work now. Not sure if it’s just from the swap of the power fc or if it’s something else?
but is it common for the AC to stop working once the power fc is installed? Some sort of tune or setting?

Yup did a search and read about the ground and fan switches being dirty broken or weak. So add a ground wire into the red wire (ground) on the fan switch and get a new fan switch or clean it should do the trick?
i see on the power fc sensor check, AC is not highlighted even when I push the AC button on the dash. I can hear the revs drop or increase and the radiator fans come on. But seems like the power fc is not recognizing the AC controls? Since it’s not lit on the power fc sensor check screen. when I turn the AC on.

Good to know the relay is the way to go. Thx for sharing. I did a quick temp hook up of the relay tonight. Started it w the AC on and on the power fc the AC setting sensor turns on now on fan 1,2,3,4. With it 0 it turns off.
but I go to see the AC compressor and it’s not turning on…
