Hzj75 1hz aircon.

[Buazza]

Hi gents. Need some help! Struggling with my rig right now. Iv got a hzj75 1hz 1992 model.
Im busy changing the whole wiring harness for my rig. I put a complete wiring harness for a hzj79 1hz on my rig. Evrything is pretty simple and straight foward. The only issue im facing with is the A/c. The a/c clutch isnt engaging when i switch on the a/c from the dashboard. What could be wrong? I just refilled gas and the compressor is engaging when you connect it direct to the battery. Anybody who can help me please? Any kind of help will be appreciated. Anyone got a wiring diagram from the a/c please help me. TIA. Cheers.

BJ74 A/C repair, help needed

I knew the a/c did not work but I took a closer look today. With heating/cooling controls set to a/c and very cold, the a/c compressor clutch does not get actuated; pulley spins freely as if a/c was not called for. What is my next step?

Pressure switch may be bad.
