Can the air conditioner be turned on when the car is powered?

You can turn on the air conditioner when the car is powered, but here are the details: 1. Compressor function: The car can turn on the air conditioner without starting the engine, but the air conditioner will only blow natural air from the blower. The air conditioning compressor is driven by the engine's power, so when the car is turned off, the compressor naturally stops working. The natural air blown by the blower is powered by the battery, and excessive use of the blower may drain the battery over time. This applies only to traditional fuel-powered vehicles. 2. Interlock mechanism: Modern cars have an interlock mechanism that automatically cuts off most auxiliary circuits after the engine is turned off, including the air conditioner and blower. Leaving the engine running after turning off the ignition can easily damage it. The next time you start the car, the load from the air conditioner may cause excessive strain on the engine, leading to potential damage.
