A technician is working on a 2005 BMW 7 series.. The compressor is running all the time and the air is cold. The tech unplugs the wiring harness leading to the compressor, but it stays running. The technician recommends a new compressor as he suspects the clutch has melted. What is likely happening here?
nothing. This compressor doesn’t have a clutch, only a pulley
the clutch has melted due to a slipping belt
only the hub needs replacement, the pulley is fine
the compressor must be seized internally for this to happen
