What causes the Chevrolet Cruze to shake when the air conditioning is turned on?
2 Answers
The reasons why the Chevrolet Cruze shakes when the air conditioning is turned on are as follows: 1. Dirty throttle body: This affects the engine. If the air conditioning is turned on at this time, it will increase the engine idle speed, resulting in steering wheel shaking. 2. Carbon buildup in the throttle body: If the throttle body has not been maintained for a long time, carbon buildup can easily occur, which obstructs the engine's air intake, causing the engine to barely or insufficiently power the compressor, leading to idle shaking. The solution is to clean the throttle body. If the driving environment is harsh, it is best to clean it regularly, recommended every 10,000 kilometers.
As someone who frequently works on my own car, I've driven a Cruze and also encountered the issue of shaking when the AC is on. The main reason is that when the AC is turned on, the compressor activates, suddenly increasing the engine load. If the engine itself isn't properly adjusted, it's prone to shaking. Common causes include aging spark plugs leading to poor ignition, carbon buildup in the throttle body causing restricted airflow, a stuck idle control valve, or a clogged air filter affecting air intake. If the engine mounts are severely worn, vibrations are directly transmitted to the car body. A loose or insufficiently lubricated compressor belt can also increase the load. It's recommended to check the spark plugs and throttle body every six months and replace the air filter to ensure the car is well-prepared before using the AC, which can prevent many issues. In short, addressing these problems early can extend the car's lifespan and make summer driving more worry-free.
