AC not working while coolant pumps running

Has anyone had this problem. My AC will only blow hot air while the coolant pumps are running. As soon as they turn off the AC works just fine. Nothing fixes it.

Yes, I've had this happen a few times (invariably, during a long trip on a hot summer day right after finishing a supercharging session). Does this happen to you all the time or rarely?

All the time. Taking it in next week. They think it is a faulty compressor.
