Air-conditioning compressor
Circulates refrigerant for cabin cooling.
Belt-driven on many combustion cars or electrically driven on electrified designs.
Compression enables refrigerant to release and absorb heat at different points of the system.
The pump powering a heat-moving loop.
Poor cooling or noise can involve refrigerant charge, controls, leaks or the compressor.
Filters use the service schedule. Motors, controls, seals and trim are inspected for condition and operation.
A filter or switch service differs from dashboard removal or a complete seat mechanism; access can be the main expense.
An electric BMW air-conditioning compressor can also participate in vehicle thermal management.
