Refer to the shop manual for acceptable readings. Since the ECV is nothing more than an electric solenoid, test using a multimeter. To diagnose a “no cooling” or “low cooling” condition, you’ll need a shop manual. They work in conjunction with the low and high-pressure switches, cabin temperature sensors, and the HVAC head to determine when to move the swashplate angle. The external control valve or swashplate solenoids are common failures on these newer compressors. What goes wrong with a variable displacement AC compressor? In yet a third design, a sensor detects the flow rate of the refrigerant and the HVAC head uses that data to alter the swashplate angle. In other versions, a mechanical device moves the swashplate to the desired angle. That way, the HVAC head can control how much refrigerant is pumped based on the cooling needs of the vehicle. Some manufacturers use an external control valve (ECV) solenoid that pulses high-pressure refrigerant into one side of the crankcase to force the swashplate to an operating angle that results in varying stroke lengths. It depends on the vehicle brand and compressor model. That’s a simple question with a more complicated answer. If the center bolt is rotating, proceed with the diagnosis What moves the swashplate? If the pulley spins but the center bolt does not, the torque limiter slip clutch has sheared due to internal binding and the compressor must be replaced.

How to check for a sheared torque limiter slip clutchĭuring normal operation, the center bolt at the front of the pulley will rotate at the same speed as the pulley. In the event the compressor seizes, the torque limiter slip clutch will shear off the engagement points, allowing the compressor pulley to continue to spin while no longer applying rotational force to the compressor input shaft. To prevent AC drive belt disengagement in the event of a compressor seize, the compressor pulley contains a built-in torque limiter slip clutch. Here’s a youtube video that shows how a swashplate system compressor varies the amount of refrigerant it outputs. When the AC doesn’t require compressed refrigerant, the swashplate is in a neutral position where the piston stroke is zero. These new variable displacement compressors use a swashplate that varies the stroke of the pistons based on how much refrigerant pressure is metered into the crankcase of the compressor. That doesn’t mean the compressor is compressing refrigerant full-time though. Instead, the drive belt turns the compressor shaft all the time.

    This pressure forces the liquid out of the compressor and through the cooling system. Once compressed, the freon is in a volatile, high-pressure state. The compressor is powered by a serpentine belt, which provides the energy needed to compress freon refrigerant to cool the car's cabin. we recommended that car owners replace the complete AC compressor assembly because the compressor replacement core operates under extreme physical pressure.
