QUESTION: I appreciate your assistance.  I live in the Shreveport area.  To HOT to drive it to you.  

When the clutch is working i have 12 volts power going into but nothing coming out.  Dealership machanic said it was PCM loosing ground.  Changed it (PCM) didn't help.  

Does Wide Open Throttle switch or MAP or TPS have any thing to do with the A/C clutch?  

Answer
I think we might be talking about 2 different things. There is a connector right at the compressor with 2 wires. One will have power when the clutch is suppose to come one and the black wire will be ground all the time. The only thing that the PCM does would be with the ac clutch relay is that what he was talking about? OH btw what engine size do u have?
