Reasons Why Your Car Turns Off When You Turn on the AC
The reasons behind a car turning off when you turn on the AC can be complex and multifaceted. However, some of the most common causes include:
Electrical Issues
Electrical issues are a common cause of car troubles, and this problem is no exception. When you turn on the AC, it puts a significant load on the electrical system, which can cause the car to shut down. Some possible electrical issues that can cause this problem include:
- A faulty alternator that cannot keep up with the increased electrical demand
- A weak or faulty battery that cannot provide enough power to the electrical system
- A malfunctioning electrical relay or fuse that prevents the AC from functioning properly
- A short circuit or electrical overload that causes the car to shut down
Cooling System Issues
The cooling system is responsible for keeping your car’s engine at a safe temperature, and any issues with this system can cause the car to shut down. Some possible cooling system issues that can cause this problem include:
- A malfunctioning thermostat that prevents the engine from reaching the correct operating temperature
- A clogged or blocked radiator that prevents coolant from flowing properly
- A faulty water pump that cannot circulate coolant effectively
- A low coolant level that causes the engine to overheat
Engine Issues
Engine issues can also cause a car to shut down when you turn on the AC. Some possible engine issues that can cause this problem include:
- A faulty engine computer (ECU) that cannot handle the increased load on the engine
- A malfunctioning fuel system that prevents the engine from getting the fuel it needs
- A faulty ignition system that prevents the engine from starting properly
- A low oil level or dirty oil that causes the engine to overheat
