Causes of a Shaking Car When AC is On
The causes of a shaking car when the AC is on can be attributed to various factors, including mechanical, electrical, and environmental issues. Let’s explore some of the possible causes:
Mechanical Causes
The mechanical causes of a shaking car when the AC is on can be attributed to worn-out or loose components. Some of the possible causes include:
- Worn-out Engine Mounts: Engine mounts are responsible for absorbing the vibrations of the engine and transferring them to the chassis. Over time, these mounts can wear out, causing the engine to vibrate excessively, leading to a shaking car.
- Loose or Worn-out Drive Belts: Drive belts are responsible for transmitting power from the engine to the alternator, water pump, and other accessories. A loose or worn-out drive belt can cause the engine to vibrate, leading to a shaking car.
- Bad Engine Bearings: Engine bearings are responsible for supporting the engine’s rotating components. Worn-out or damaged engine bearings can cause the engine to vibrate, leading to a shaking car.
Electrical Causes
The electrical causes of a shaking car when the AC is on can be attributed to faulty electrical components. Some of the possible causes include:
- Faulty Alternator: The alternator is responsible for charging the battery and powering the electrical system. A faulty alternator can cause the engine to vibrate, leading to a shaking car.
- Bad Starter Motor: The starter motor is responsible for turning the engine over. A faulty starter motor can cause the engine to vibrate, leading to a shaking car.
- Loose or Faulty Electrical Connections: Loose or faulty electrical connections can cause the engine to vibrate, leading to a shaking car.
Environmental Causes
The environmental causes of a shaking car when the AC is on can be attributed to external factors. Some of the possible causes include:
- Uneven Road Surface: Driving on uneven road surfaces can cause the car to vibrate, leading to a shaking car.
- High-Speed Winds: High-speed winds can cause the car to vibrate, leading to a shaking car.
- Extreme Temperatures: Extreme temperatures can cause the car’s engine to vibrate, leading to a shaking car.
