Why Does My Car Idle Rough When I Turn on the Air Conditioning?
When you turn on your air conditioner, your car's engine has to work harder to overcome the increased load. This can cause your car to idle rough, especially if your engine is not in good condition.
There are a few things that can cause your car to idle rough when you turn on the air conditioner:
- The compressor clutch may be engaging and disengaging too frequently. This can be caused by a faulty compressor, a low refrigerant level, or a problem with the electrical system.
- The idle air control valve may not be functioning properly. This valve controls the amount of air that enters the engine at idle, and a faulty valve can cause the engine to idle too fast or too slow.
- The fuel injector may be clogged. This can cause the engine to run lean, which can lead to rough idling.
If you are experiencing rough idling when you turn on your air conditioner, it is important to have your car inspected by a qualified mechanic. They can diagnose the problem and make the necessary repairs.
