AC on 96 3.0 V6
The air conditioning clutch isn't kicking in. Before it quit kicking in
at all, it put out very cold air. I checked fuses and connections and they all seem to be good. Next, I checked the CCRM connector. Pin 21 shows normal voltage but pin 22 and 23 are dead (0 voltage). According to my trouble shooting guide, 0 volts on 22 indicates that the PMC has detected a problem with engine operation and won't let the clutch engage. My pocket scan indicated that there were no codes. Any ideals? |

Instead of doing it the hard way... disconnect the low pressure cut out
switch and short across the terminals (harness side). Does the clutch engage? If yes, there is a chance that the switch is bad or the refrigerant charge is low. It really doesn't matter what it did before it failed.... simply because sh*t happens. "Granville" > wrote in message news > The air conditioning clutch isn't kicking in.
