A/C compressor control valve significanceThe A/C compressor control valve has the task of maintaining the evaporator at a steady temperature above freezing for optimal A/C system operation. Modern vehicles typically come equipped with compressor control valves that are electronic. Mechanical control still plays a role in older models or economical cars but they cost extra. While the electronic control valve is more productive, saves the A/C system from wear, and lessens the engine load.
