How to Solve the Problem of Car Shaking When the Air Conditioner is On?
2 Answers
After starting the car, turn on the air conditioner, and you may notice a slight decrease in vehicle power. If the vehicle power is significantly reduced when the air conditioner is turned on for cooling, you can consider cleaning the carbon deposits in the car engine. If the above steps have been taken and the car still shakes, you may want to check if there is an issue with the fuel supply. If there are cooling problems with the car air conditioner, it is advisable to visit a 4S shop for inspection as soon as possible. When parking, try to park in a shaded area or an indoor parking lot to help lower the temperature inside the car.
Last time I encountered this issue, I drove straight to my trusted repair shop for an inspection. The mechanic explained that turning on the AC increases engine load, and if the engine mounts are worn out with reduced damping effect, you'll feel vibrations. After they replaced the new engine mounts, the improvement was immediate. They also cleaned the throttle body and fuel injectors for me. Actually, many cars experience vibrations when the AC is on due to this reason, especially older vehicles that have been driven for seven or eight years, as the rubber in engine mounts naturally deteriorates. Besides getting it fixed, I've learned to regularly check the condition of engine mounts and replace them promptly if cracks appear. Now, there's no more vibration when I turn on the AC. During routine car washes, I also ask the mechanics to inspect the condition of these wear-and-tear parts, which helps prevent many potential issues.
