Why Should You Turn Off the Air Conditioning Before Shutting Down the Car?

[VanHarley]

Here is more information about why you should turn off the air conditioning before shutting down the car: 1. When using the air conditioner in summer, if you only turn it off when parking and shutting down the engine, it is easy for mold to grow inside the air conditioning system. 2. In summer, with high temperatures and humidity, there is a lot of moisture left in the air conditioning ducts and evaporator after turning off the air conditioner. This moisture does not dry completely, making it particularly prone to mold growth, which can lead to a sour smell in winter. 3. Before parking and shutting down the engine in summer, turn off the AC button and only keep the fan running to dry the moisture in the ducts and evaporator. This will prevent mold growth. If the sour smell is too strong, you can only go to an auto repair shop to disassemble and clean the ducts and evaporator.
