Why Does My Car Shake When I Turn on the AC?

When you turn on your car’s air conditioner, you may notice that the vehicle starts to shake. This is a common problem that can be caused by a variety of factors. In this article, we will discuss the most common causes of car shaking when the AC is turned on and provide some tips on how to fix the problem.

Definition

Car shaking when the AC is turned on is a condition in which the vehicle experiences vibrations or shaking when the air conditioning system is activated. This shaking can be felt in the steering wheel, seat, or floorboard of the car.

Types

There are two main types of car shaking when the AC is turned on:

  • Engine vibration: This type of shaking is caused by the increased load on the engine when the AC compressor is engaged. The compressor is a mechanical device that pumps refrigerant through the AC system. When the compressor is turned on, it puts a strain on the engine, which can cause the vehicle to shake.
  • Driveline vibration: This type of shaking is caused by the transfer of vibrations from the engine to the driveline. The driveline is the system that transmits power from the engine to the wheels. When the engine is shaking, these vibrations can be transmitted to the driveline, which can cause the car to shake.

Differences

The main difference between engine vibration and driveline vibration is the source of the vibrations. Engine vibration is caused by the engine itself, while driveline vibration is caused by the transfer of vibrations from the engine to the driveline.

Ease

The ease of fixing car shaking when the AC is turned on depends on the cause of the problem. If the shaking is caused by engine vibration, it may be a simple matter of adjusting the engine mounts or replacing the compressor. If the shaking is caused by driveline vibration, it may be necessary to replace the driveshaft or other components of the driveline.

Process

The process of fixing car shaking when the AC is turned on typically involves the following steps:

  1. Inspect the engine mounts and compressor for signs of wear or damage.
  2. Replace the engine mounts or compressor if necessary.
  3. Inspect the driveshaft and other components of the driveline for signs of wear or damage.
  4. Replace the driveshaft or other components of the driveline if necessary.

Advantages

There are several advantages to fixing car shaking when the AC is turned on. These advantages include:

  • Improved ride quality
  • Reduced wear and tear on the engine and driveline
  • Increased fuel efficiency

Disadvantages

There are no disadvantages to fixing car shaking when the AC is turned on.

How

To fix car shaking when the AC is turned on, you will need the following tools and materials:

  • Socket wrench set
  • Screwdriver set
  • Pliers
  • New engine mounts (if necessary)
  • New compressor (if necessary)
  • New driveshaft (if necessary)

What

Once you have gathered the necessary tools and materials, you can follow these steps to fix car shaking when the AC is turned on:

  1. Inspect the engine mounts and compressor for signs of wear or damage.
  2. Replace the engine mounts or compressor if necessary.
  3. Inspect the driveshaft and other components of the driveline for signs of wear or damage.
  4. Replace the driveshaft or other components of the driveline if necessary.

Conclusion

Car shaking when the AC is turned on is a common problem that can be caused by a variety of factors. In most cases, the problem can be fixed by replacing the engine mounts or compressor. If the shaking is caused by driveline vibration, it may be necessary to replace the driveshaft or other components of the driveline.

FAQ

Q: Why does my car shake when I turn on the AC?
A: Car shaking when the AC is turned on is typically caused by engine vibration or driveline vibration. Engine vibration is caused by the increased load on the engine when the AC compressor is engaged. Driveline vibration is caused by the transfer of vibrations from the engine to the driveline.

Q: How can I fix car shaking when the AC is turned on?
A: To fix car shaking when the AC is turned on, you will need to replace the engine mounts or compressor, or replace the driveshaft or other components of the driveline.

Q: How much does it cost to fix car shaking when the AC is turned on?
A: The cost to fix car shaking when the AC is turned on will vary depending on the cause of the problem. If the shaking is caused by engine vibration, it may cost around $100 to replace the engine mounts. If the shaking is caused by driveline vibration, it may cost around $500 to replace the driveshaft.

Closing Statement

Car shaking when the AC is turned on is a common problem that can be caused by a variety of factors. In most cases, the problem can be fixed by replacing the engine mounts or compressor. If the shaking is caused by driveline vibration, it may be necessary to replace the driveshaft or other components of the driveline.
