Experience the cold AC without the rush of a shake! We’re unraveling the mystery of why your automobile behaves erratically every time you turn on the air conditioning.
1. Worn-out foundations and engine mounts
The engine experiences an increased strain when the air conditioning is turned on, which makes it vibrate more than normal. The engine mounts’ purpose is to dampen vibrations and maintain engine stability, but when they deteriorate, they can no longer perform this function as intended. The car shakes as a result of the engine vibrating significantly.
Metal-on-metal contact may result from a damaged engine mount in some circumstances, which may audibly rattle the engine. To prevent more harm to your vehicle, it’s critical to get your engine mounts inspected and replaced as soon as you suspect they may be worn out or broken.
2. A clogged or dirty air filter
When the air conditioning is turned on, an unclean or clogged air filter can impede the airflow into the engine, making it work harder and vibrate more. This may lead to a discernible vibration, as well as a reduction in power and fuel economy. It’s a good idea to have your air filter changed if it hasn’t been done recently to see if that helps.
3. AC Compressor Not Working Correctly
The refrigerant that cools the air in your automobile is compressed and circulated by the AC compressor. Excessive vibrations and shaking may result from the AC system having to work harder than usual if the compressor isn’t working properly. A malfunctioning compressor can occasionally make odd noises as well, such screeching or grinding. It’s better to get your AC compressor evaluated and fixed by a qualified mechanic if you think it might be the problem.
4. Worn-out or loose belts
The power transfer from the engine to different parts of your car, including the AC compressor, is done by the belts in the engine. The automobile may shake if these belts are worn out or slack because they could slip or vibrate when the air conditioning is on. An occasional high-pitched screaming sound may also be produced by a loose or worn belt. Any worn-out or loose belts on your car should be replaced right away to prevent additional harm.
5. Low Levels of Refrigerant
Your car’s air conditioning system might have to work harder than usual to chill the air if there is not enough refrigerant in it. This may result in a reduction in cooling efficiency as well as vibration and shaking of the engine. A system leak or a broken part, like the compressor or evaporator, might result in low refrigerant levels. It’s crucial to get the AC system examined and fixed by a qualified mechanic if you think your automobile may be short on refrigerant.
6. Distressed Spark Plugs
Spark plugs are a crucial part of the engine in your car since they light the fuel in the combustion chamber. When the air conditioning is on, the engine may misfire and vibrate due to worn-out or filthy spark plugs. Wearing out spark plugs can occasionally result in a drop in power and fuel efficiency. It’s critical to have any worn-out spark plugs replaced as soon as possible to prevent more engine damage.
How to Adjust Shakes in a Car with AC On
Air Filter: It could be necessary to replace an air filter if it is unclean or blocked. To find out when to replace your car’s air filter, see the owner’s manual or have a mechanic look it over.
Malfunctioning AC Compressor: An experienced mechanic is required to examine, fix, or replace a malfunctioning AC compressor.
Worn-out or Loose Belts: Belts that are worn-out or loose may need to be replaced or tightened. The belts can be inspected by a mechanic, who can also perform any necessary repairs or changes.
Low Refrigerant Levels: A mechanic can check the AC system for leakage and replace or repair any broken parts if the refrigerant levels are low.
Spark Plugs That Are Worn Out: Spark plugs that are worn out must be changed. To find out when the spark plugs in your automobile need to be changed, see the owner’s manual or have a repair look them over.
FAQs
Why does the air conditioning in my car tremble?
A dirty air filter, low refrigerant levels, a malfunctioning AC compressor, loose or worn-out belts, worn-out engine mounts or foundations, and worn-out spark plugs are just a few of the problems that can cause a car to shake when the air conditioner is running.
When the AC is running and my car is trembling, is it still safe to drive?
Driving a car that is trembling when the air conditioning is on is typically not advised because this could indicate a significant problem. Driving the vehicle in this state may result in more damage and perhaps unsafe circumstances. It’s best to get the problem looked at and fixed as soon as possible by a qualified mechanic.
What is the price of fixing a car that trembles while the air conditioning is on?
Depending on what’s causing the problem, fixing automobile tremors while the air conditioner is on can come at a different cost. It might be as easy as swapping out spark plugs or a dirty air filter, or it can be as difficult as replacing worn-out engine mounts or a broken AC compressor. It is advisable to have the problem inspected and a cost estimate given by a qualified mechanic.
When the AC is running, can I fix the shaking in my car myself?
Some car owners with some mechanical skill can address certain causes of their car shaking when the air conditioner is on, like changing a dirty air filter or worn-out spark plugs. More complicated problems, on the other hand, such changing worn-out engine mounts or a broken AC compressor, are best left to qualified mechanics with the right equipment and knowledge.
How do I stop my car from swaying when the air conditioning is running?
Frequent auto maintenance can help avert future problems, such as air filter replacements, tune-ups, and oil changes. Furthermore, addressing minor concerns as soon as they emerge helps save them from developing into more significant and costly issues.
There are several reasons why a car will shake when the air conditioning is on, from easy fixes like changing the spark plugs or dirty air filter to more involved ones like replacing worn-out engine mounts or a broken AC compressor.
Driving a car that is trembling while the air conditioning is on can result in additional harm and even unsafe circumstances. In order to guarantee that your automobile operates smoothly and safely, it’s critical to have the problem looked at and fixed by a qualified mechanic as soon as possible.
