Why is my car vibrating when AC is on?
When you turn the AC on, the vehicle engine triggers elements such as idle speed or air control motor. You can increase the idle compressor by compensating with an additional drag. The inaccuracy in this process causes the vehicle to shake when AC is on.
Can the AC compressor make your car shake?
AC compressor puts a strain on the engine and in a situation when the load goes above a certain extent, it eventually leads to vibration. If the load continues to increase, some parts of the engine can wear out ultimately. In such a condition, take your car to the nearest AC technician as soon as possible.
What are the causes of engine vibration?
5 Causes of Engine Vibration
- Worn Out Spark Plugs. In many vehicles a common cause of engine vibration is worn out or faulty sparkplugs.
- Loose or Disconnected Hoses.

- Faulty or Poorly Adjusted Fuel Intake System.
- Faulty Timing Belt.
Why is my engine shaking when idle?
While a shaky idling car can certainly feel like an earth-rumbling tremor, it can also indicate a problem with the engine. One common cause of shaking while idling can be loose engine mounts. Alternatively, a car that shakes when idle may have faulty fuel injectors, worn-out spark plugs, or a bad timing belt.
What causes rough idle when AC is on?
A rough idle when the air conditioning is on may be caused by: A faulty or dirty IAC valve. A dirty throttle body. A faulty cooling or condenser fan.
Why do my rpms fluctuate at idle with AC on?
It is common to see a small fluctuation in RPM when the AC turns off and on due to the drag on the engine. It should not drop that much though. It sounds like the idle control system is not functioning properly. Most of the time the fix is as simple as reprogramming the computer.
Why does my engine vibrate when idle?
Motor mounts keep your engine attached to the car. Weak or broken mounts can’t hold the engine tight in the engine compartment and creates a vibration at idle. If the shaking subsides when the car is in Neutral, this could indicate the motor mounts are responsible for the vibrations.
