    Hey all,

    I've got a 2001 ZX2 with an air-conditioning problem that has stumped me. It is full of refrigerant, tested leak-less, but it won't blow cold air. When I switch it to A/C, the cooling fan kicks on, and the compressor cycles on/off once a second - waaaaay too quickly. I don't want to burn the clutch out - what could I do to fix it, or how do I disable it?

    If you are 100% sure its full of freon! Unplug the cycle switch and jump the 2 wires together. If the AC gets cold replace the cycle switch. DO NOT LEAVE THE SWITCH JUMPED FOR AN EXTENDED AMOUNT OF TIME YOU'LL KILL THE COMPRESSOR. The switch is located on top of the suction accumulator.

    A pressure check would be best though. It could be high pressure cycling the ac off. Your fan should be on high speed instead of low if head pressure is high.

    Leaving the cycle switch unplugged will disable the clutch. You could also just not turn the AC on :wink:

    This may seem out there but, Does your car have cruse control? IF it does is it working? IF thats not it could be a bad ccrm relay. Its possible even without the cruise control going out, the car might think it at wot and killing the ac.

    It doesn't have cruise. It's cycling the compressor every two seconds, approximately. I doubt it's assuming WOT, but I could be wrong.

    You need to put gauges on it to find out what is going on. Start there. If you don't have access to gauges or don't know how to use them, have it done. No sense in jerking around with system components if you don't have pressure readings to work with.

    It probably needs more refrigerant. This summer mine didn't seen to be cooling as good as it should have been. The low side pressure gauge read normal, the cycling was also normal, yet I was able to add a whole can of refrigerant (about half the system capacity) to it and the gauge was still well in the normal range! It improved the cooling performance by a reasonable amount.
