A/C won't restart after full throttle

does the ecu shutdown power to the a/c compressor at wot? some cars are programmed to do this. if so, then it does sound like a bad relay or switch.

I don't think our cars have this feature. Vehicles with small displacement engine might have this feature, but not for high hp vehicles.

I'm not sure what parameters it looks at (may be in the FSM), but the car does turn off the A/C compressor when you give it a lot of throttle. Most (all?) cars I've owned did. I've always assumed it was to get rid of the extra load when under hard acceleration, but don't know for sure.
