Cat 988F Air Conditioning Compressor not engaging clutch

988Driver · 2021-10-17 22:47

Hi all, I have recently replaced the blower motor in the air conditioning unit on my 988F. Prior to this all pressures were fine and the unit was working well. Now the clutch is not engaging on the compressor. I have voltage to the compressor and have just replaced the compressor thinking that could fix the problem but nothing. Gauges were showing low side to be high and high side to be low. I also have a replacement thermostat and TX valve available to be fitted but I don’t think these are the problem. Is there anything I could be missing? thanks for your help.
