What happens when the steering wheel shakes when the air conditioner is idling?

If the owner notices noticeable body shaking while idling, then you better check these places.

1. Serious carbon deposition in the engine: carbon deposition in the engine is the main reason for the shaking of the car, when there is too much carbon deposition inside the engine, the gasoline sprayed by the cold start injector will be absorbed by a large amount of carbon deposition, resulting in too thin mixture for cold start, resulting in more difficulty during cold start.

Solution: Regularly clean the oil circuit, check the idle motor, and clean the throttle.

2. Ignition system failure: spark plug is a wearing part, which needs to be replaced regularly, if it is found that the spark plug has too much carbon deposition or the ignition gap is too large, it needs to be replaced, and it is also necessary to check the working state of the line: high-voltage wire and ignition coil, and the car computer can be used to determine the state of the ignition system.

3. Oil pressure problem: whether the fuel supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is abnormal or the intake pressure sensor value is wrong and the work is poor, it will cause the body to shake. The most common time for engine idle shake is when the electrical system is turned on, if you step on the brake to hang D gear, turn on the air conditioner (AC compressor switch to turn on), turn on the headlights, the engine begins to shake, and the speed does not drop because of the load of the compressor, which can be determined to be the problem of aging of the engine's "foot glue", and the problem of shaking can be solved by replacing the foot glue.

Check it out with a professional maintenance master.

In the case of switching on and off the air conditioner, idling, the steering wheel is a little shaky, it should be a problem with the throttle, you need to clean the throttle, and then make a throttle matching, which needs to be matched by the computer.

Turn on the air conditioner and the steering wheel is shaking, how to solve it If the air conditioner is turned on, it will shake up, it is really cool to ask for a solution, wash the throttle fuel injector, thank you.

1.It is possible that the throttle is dirty and needs to be cleaned.

2.Inferior fuel oil was added.

3.The spark plug needs to be replaced.

4.If it's neither, it may be a problem with the throttle assembly.

The engine drives the resonance of the air conditioning compressor. There is also the steering knuckle cage that may be problematic.

When idling, you will find that many cars will vibrate relatively large, the resonance frequency of the whole vehicle and the resonance frequency of the engine idle is relatively close, this is difficult to improve, the engine idle is actually an unstable working process, the speed is relatively unstable, the amplitude is relatively large, generally speaking, it will not affect safety, but the car should be as little idle as possible. Regarding steering wheel jitter, most of the resonance compensation is not well balanced, in fact, the steering wheel will shake in the car, some will appear at idle, some will appear at high speed, some will be at low speed, not necessarily, most of them are still at idle more, because at this time will not have an impact on your driving safety. If the same model as you is like this, then it is not a big problem, if not, then you still have to reflect the inspection, because if you are a special case, there may be some hidden dangers that cause this.

Turn on the air conditioner and the idle steering wheel is shaking, how to solve it.

Turn on the air conditioner only slightly shake, if the air conditioner is turned on, it will shake up, it is really cool, ask for a solution, wash the throttle fuel injector, thank you.

The reasons for the steering wheel shake after turning on the air conditioner: 1. The engine will shake slightly if the throttle valve is too dirty, but it is usually not easy to detect the dust, once the air conditioner is turned on, the engine load increases, and the shake will be aggravated; 2. The power of the vehicle is too small and the automatic transmission is not enough, and the power is not enough at high speed, plus a high-power air conditioning system, so the steering wheel shake aggravates the first stove, if the vehicle is self-priming with a small displacement, it is likely to be this reason; 3. The damage of the air conditioning compressor is accompanied by shaking, and the problem is that the air conditioner does not produce cold air, but the blower has been ringing, if these two phenomena occur, then 90% may be the problem of the compressor. The on-board air conditioner is an air conditioning system consisting of a compressor, a condenser, a throttling element, an evaporator, a fan, and the necessary control components to regulate the temperature and humidity in the vehicle and provide a comfortable environment for the occupants.

The reason for the obvious shaking of the air conditioning steering wheel: it may be that the throttle valve is too dirty, which affects the engine, and if the air conditioning is turned on at this time, the engine will be idle and the steering wheel will shake. Or the vehicle power is too small, the air conditioning compressor is damaged, etc., which may cause the steering wheel to shake.

The reasons for the obvious shaking of the steering wheel of the air conditioner are as follows:

1. The throttle is too dirty.

At this time, the engine will shake slightly, but it is not easy to notice, and once the air conditioner is turned on, the engine load increases, and the shake will be intensified. Solution: Wash the throttle, and check whether the condenser is dirty and blocked, and whether there is any problem with the ignition system.

2. It may be that the power of the vehicle is too small, and because of the automatic transmission, the power is not enough at high speeds, coupled with a high-power air conditioning system, there are some suspicions of "small horse-drawn carts", so the steering wheel shake is intensified. If the vehicle is self-priming with a small displacement, this is most likely the reason.

3. The air-conditioning compressor is damaged.

This is the most serious reason, because once damaged, there is basically no possibility of repair, only replacement. Generally, this is the case for old cars that are more than 6 years old, and it is basically not for new cars. Along with the shaking, the problem also arises that the air conditioner does not produce cold air, but the blower keeps ringing.

If both of these phenomena occur, then the 90 could be a problem with the compressor.

Turning on the empty steering wheel and the obvious jitter may be due to the throttle being too dirty, affecting the engine. If it is turned on at this time, or the power of the vehicle is too small, or the empty compressor is damaged, etc. , which may cause the steering wheel to shake.

on The reasons why the empty steering wheel has obvious wobble are as follows:

1.The throttle valve is too dirty.

The engine shakes slightly, but it is usually subtle. Once the engine is turned on empty, the engine load will increase and the shaking will increase. Solution: Just clean the throttle and check whether the lower condenser is dirty or clogged, and whether the ignition system has any squeezing problems.

2.It may be that the power of the vehicle is too small, and because of the automatic transmission, the power is not enough at high speeds. In addition, the high-power air adjustment system is suspected of being a "small horse-drawn cart", and the steering wheel shake is intensified. If the vehicle is self-priming with a small displacement, this is probably the reason.

3.The empty compressor is damaged.

This is the most serious reason, because once damaged, there is no possibility of repairing the base game, so it can only be replaced. Normally this happens in old cars over the age of 6, but not in new cars. At the same time, there is also the problem that the air conditioner cannot be adjusted, but the blower keeps ringing.

If both of these phenomena occur, then 90% of the time it is likely to be a compressor problem.

Summary. Hello, don't worry, I can ask for your question, but wait a minute, I need text for about 2 minutes.

Hello, don't worry, I can ask for your question, but wait a minute, I need text for about 2 minutes.

Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! The reason is that the question of the rubber of the machine foot is 1After the foot glue is damaged, the cushioning effect is lost, and the normal vibration of the engine is transmitted to the body.

That's why it's shaking. 2.The foot glue is damaged, and the foot rubber must be replaced, so I hope mine can help you.
