A/c compressor continuously runs even when turned off
So my ac compressor is continuously running, even when I am not using it. What would cause this to happen? My ac blows cold and works fine, it's just that the compressor doesn't disengage when I shut it off from the panel inside. Where would I begin troubleshooting? Thanks in advance!

I checked for power down at the compressor and worked my way back until I realized that the ECU was constantly commanding the compressor to be on even when the switch was off. I sent the ECU to be repaired at lextech.org

the fact that its blowing air when its off tells me something is screwy at the ECU/panel level. A sticky clutch you can check by hand when the car is off. It should be free and spinning when not engaged. If its stuck tot he pulley, it won't spin.
