No power to AC

[RollOver_Pete]

2006 3500, no codes, no power to the clutch or pressure switch with the ignition on or off. Fuses are ok, the AC light comes on and the blower blows. Low and high side pressures are ok with no freon leaks. Where else should I look? I have yet to run a jumper to the AC clutch. If I do, which wire on the plug gets 12V?

could it be the dash switch? did you check the relay?

There is no AC relay in an 06. I guess I'll have to start looking under the dash...
