Does the air conditioning work if the car doesn't start?

You can turn on the air conditioning in a car without starting the engine, but it is not recommended. Running the air conditioning without starting the car may drain the battery, making it impossible to start the engine later. When the car is not running, the air conditioning only blows natural air from the blower, as the compressor, which is powered by the engine, does not operate when the engine is off. Here is more related information: The dangers of running the air conditioning without starting the car: Leaving the air conditioning on after turning off the engine can cause significant damage to the car. Most modern cars have a safety mechanism that automatically cuts off auxiliary circuits when the engine is off, including the air conditioning. Failing to turn off the air conditioning before shutting down the engine can damage it, as the air conditioning load during the next startup may place excessive strain on the engine. If you must run the air conditioning without starting the car, choose a well-ventilated area and open the windows every ten minutes for fresh air. According to experiments, in an enclosed space, a car with the air conditioning on can reach dangerously high levels of carbon monoxide in just 20 minutes, leading to a noticeable feeling of suffocation.
