My clutch is not engaging, and my electric fan is not turning on. When I turn on the A/C the blower turns on, aswell as the RPM's rise to accept the expected load, however I get no clutch activation and no fan. If I hotwire the clutch and fan they work fine... I have checked the relays and they are fine. I have also bypassed the Low Pressure Switch, and all it does it pick up the RPM;s, and does not force the compressor on. As a last resort I am hoping there is a fuse somewhere for the A/C cicuit.
