I have a problem with my AC system in which the compressor runs constantly while the engine is running. I can turn off the AC button on the climate control panel, but the compressor still runs. I checked the clutch and it's not stuck. I removed the compressor relay and the compressor stopped running, but when I replaced the relay with a different one it again runs constantly. I disconnected the climate control panel completely and the compressor still runs.
