I'll need more time to investegate this one. If the air doors are moving, and the compressor is turning off, and the fan quits on acceleration, it's a MUCH more in depth problem than just a charge. I'll try to find some wire diagrams and see what runs where.
It is a possibility that something is getting shorted out. Just don't know what yet. If I can't fin out the solution, maybe we can work to eliminate some possabilities before turning it over to someone else.[/Quote:4fdb18a1b3]At 1st I thought it was vacuum related. I was thinking map sensor. It seems like the wide open throttle switch was kicking in early. I thought that was controlled by the map sensor. The truck runs fine other than the rattle coming from the catalytic converter. Are the a/c controls run by vacuum? That was another thought I had. It deffently has something to do with engine load. Thanks for all of your help.
