Hey all! In short, I have a redtop Sr in my kouki. Wiring Specialties wiring harness. The A/C compressor will kick on just fine, R134a canister shows good pressure when it's running, but the air never gets cold... I can swap an engine, take it apart and put it back together but I'm clueless to air conditioning..

Is the mix door moving? Stick your head under the dash and look/listen for anything moving while you move the temp adjuster.

Have you checked the pressure on the high and low sides of the a/c? There could be a clog(or possible stuck expansion valve) some where in the system causing the issue.
