Four Seasons A/C Compressor P/N:57664
Four Seasons 78396 A/C compressor for the 2001-2006 BMW 325Ci and other vehicles circulates refrigerant through the A/C system. It is a new Denso 7SB16C compressor with the clutch included.
Weak cooling, a noisy compressor or a clutch that does not engage can mean the compressor is worn, though a failed clutch relay or a restricted condenser can produce the same signs.
It also fits the 2001-2006 BMW 325i and the 2001-2006 BMW 330Ci, and each of those takes one compressor. For any other BMW, find its year and model in the "Vehicles it fits" section.

My A/C blows warm air, could the compressor be the cause?
