I just realized the A/C compressor is running 24/7 on and off as if I had the A/C on but actually it is off just the vent is on. Nothing changes when I turn the A/C on and switch it back off. As long as the vent is on 1-2-3 the compressor is turning on and off in every 15 seconds. Pretty annoying to run the A/C compressor all the time. Any suggestions to turn it off?
