It now works--sort of....

So Joe and I have been working on putting air conditioning in his '88 Pioneer, as Texas heat can suck...especially this year. We finally found the harness I put together last year for underhood, so we wired it up, and with the dealer A/C connectors a part of the setup, we got the electricals put together and charged the system. It engages, the electric fan turns, and it gets cold. But, the A/C dash controls are having troubles. In each A/C setting the air is not coming out where it needs to. I have the control table from the manual, and I verified the source vac is strong (20"), but even with a spare control unit, I'm still not getting proper controls. Anyone have any ideas?

Did you manually test all the actuators to verify they will open the doors? I have had the recirc actuator go bad and be plugged to where it won’t let vac draw from it to open the door.

The system default to defrost if the vacuum is lost or not correct
