How does the APAD and ACPU system lubricate the compressor and components all year long?

Question

Quizplus · Accepted Answer

The APAD (Ambient Pressure And Temperature Dependent) and ACPU (Air Conditioning Pressure Unit) systems engage the compressor for a short period after the vehicle starts. This action ensures that the oil, which lubricates the compressor and other components, circulates throughout the system, maintaining lubrication even when the air conditioning is not in use for extended periods, such as during colder months. This process helps prevent the compressor and other components from drying out and becoming damaged.
