Why Does the Car Stall When the Air Conditioner is Turned On?

[StFelix]

The reason why the car stalls when the air conditioner is turned on may be due to low engine idle speed. The low idle speed causes the engine to stall when the vacuum in the intake manifold changes during braking. Low Engine Idle Speed: Damage to the vacuum booster pump, a cracked rubber hose connected to the vacuum booster, or improper connection can cause unstable idle speed and stalling. The solution is to clean the idle valve or replace the vacuum booster pump or rubber hose. The car air conditioning system generally consists of components such as the compressor, electronically controlled clutch, condenser, evaporator, expansion valve, receiver-drier, piping, condenser fan, vacuum solenoid valve, idle speed controller, and control system. Automobile Air Conditioning System: Commonly referred to as car air conditioning. It is used to regulate and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to optimal conditions, providing a comfortable riding environment for passengers and reducing travel fatigue. It also creates favorable working conditions for the driver, playing a crucial role in ensuring safe driving as a ventilation device.
