I am trying to troubleshoot an Air Conditioning problem on a '13 328I. When I put the AC on max and blower on full, fan runs, idle increases, and everything seems to work fine except compressor clutch does not engage. There is a wire harness on the compressor with 2 white wires and a brown wire. Can't find anything on what each wire is and which ones provide power to engage the clutch.
