What does the car sync switch indicate?

[SanGeorge]

Car sync switch refers to the temperature synchronization button for dual-zone automatic air conditioning in vehicles. The car air conditioning system is an important comfort feature in automobiles, capable of both cooling and heating, making it essential for use during both winter and summer seasons. When the car air conditioner is in cooling mode, the compressor clutch engages, allowing the engine to drive the compressor operation. The running compressor continuously compresses refrigerant and delivers it to the evaporator. Automotive air conditioning refers to the air conditioning device installed in vehicles that can cool, heat, ventilate, and purify the cabin air, providing passengers with a comfortable riding environment. It helps reduce driver fatigue and improves driving safety. The air conditioning system has become one of the indicators for evaluating whether a vehicle is fully equipped with necessary functions.
