A/C compressor not engaging

[Onizuka]

I left my KA A/C stuff in the car and hooked it up to the SR easily. Now it was working before I took the KA out, and im pretty sure the A/C wiring is independent of the SR motor harness, but the compressor wont turn on for some reason. Any tips would rock hard.

Of course I waited until the end of summer to ask but better to fix now than never

LoL, I'm just like you...waiting til the end of summer to get the ac to function. Anyhow I think in your case it might be a bad compressor clutch.

well.. i know that for the a/c you had to have repinned the pins on the two connectors near the battery tray. i believe it was a 8pin grey connector, and a smaller brown connector. If i am not mistaken there are a couple wires that must match, the plugs plug up and all but if you look closely at the location of the wires on the plugs some of them don't match up, just move them around to match color for color. i think the one responsible for the clutch engagement is a blue/green wire, and something else.

thats the best i can do for you now, try that

If there is no pressure in the line (no refrigerant) or not enough, the clutch won't engage. That's also a posibility.
