Denso 7SEU17C in a 2006 BMW E90, N52 engine. Noticed that it's no longer blowing cold air eventhough refrigerant gas was filled last year and there were no leaks.
The clutch pulley in the video is engaged even when AC is off. When I press AC on, it looks the same. AFAIK, the pulley should disengage when AC is off. It does affect my engine RPM by like ~150 but that could be controlled by the ECU, not compressor.
It doesn't make sense, if the clutch is stuck on it should still blow cold air?
No fault codes.
