Why Does My Car Shake When I Turn the AC On?
The most common reasons for your car shaking when the AC is on include a faulty AC compressor, damaged or worn motor mounts, bad spark plugs, faulty fuel injector, and too much engine load.
When you activate the AC, the engine initiates various components such as idle speed or air control motor. The imprecision in this process can lead to the car shaking when the AC is on.
Is the shaking in your car related to the AC?
When the AC is turned on in a car, it can cause shaking or vibrations due to the added load on the engine caused by the air conditioner compressor. This can make issues with the idle air control more noticeable, as the engine requires more air to continue running.
If the AC compressor and motor mounts in the car are not functioning properly, they may place strain or pressure on the engine when the AC is turned on, leading to shaking or vibrating. This can be caused by a damaged AC compressor or a faulty motor mount.
The shaking of the car when the AC is turned on not only affects comfort, but it can also impact the overall performance of the vehicle. It is important to address and resolve these issues to prevent premature wear on engine components and ensure optimal performance.
