I ordered a reman R4 compressor and got it all installed and working. But now it seems when it kicks off (if its even suppose to be kicking off, like when its in max AC) it wont kick back on. When it first happened I got under the hood and put a test light on the coil wires while it was running and I had power, I touched the clutch and it grabbed and pulled in. Now that this happens more often, I pop the hood and tap the clutch with a screwdriver handle, or sometimes I can rev the engine hard and it will pull in. I can see this process is going to get old quick so could you tell me how to adjust or check and solve this problem please?
Also on another note, my control panel is out of adjustment. When you first turn it on, it hits max before the lever does and at the other end of the spectrum, it has a hard time switching it to defrost when pushed all the way to the right. Are these easy to adjust if pulled apart or is it the vacuum switch or something else. I greatly appreciate your help and advice, Thank you!

Get a GM clutch installer tool and push the clutch plate on further. Gap should be less than .020 inches, it can be closer as long as the clutch doesn't rattle or drag when off. You may want to also have the remover tool on hand in case you go too far.
