Waited 3 weeks for them to get the parts from Germany. They changed the compressor and it was working fine for 2 days but at the 3rd day the ac stopped working again.First and most importantly, make sure your thermostat is set to Heating Mode. Next, verify that the thermostat's fan is set to AUTO, not ON. If it is set to ON, that may be your problem; switch it immediately. The ON setting makes the furnace fan blow continuously, even when the heating cycle is not activated.
2011 X5 535i - with clima set to 60 degrees for both the driver and passenger and AC turned off, my ventilation blows really hot air. When turning the AC on, it acts normally, the expected cold air.
