Car Air conditioner is one of the most important parts in a car. It keeps your car temperature at the optimum that you can drive comfortably. Sometimes the car shakes when Ac is on and this could happens due to different issues.
When I first experienced a car shaking as soon as the AC was switched on, I was confused and worried about what could be causing it. After researching and consulting with professionals, I realized that this is a common problem; fortunately, there are steps to fix it.
The Severity of the Issue
It can be alarming when your car starts shaking as soon as you switch on the air conditioning. But just how serious is this issue?
In short, it depends on the root cause. If clogged air filters are to blame, then you’re looking at a relatively benign problem that can easily be fixed with a few simple steps. However, if there’s an underlying issue related to engine oil levels or transmission system failure, you need to take swift action to avoid further damage.
To determine exactly how difficult the current situation is and what steps must be taken to rectify it, you must examine each potential cause and its solution in detail. In this blog post, we will look at all of these factors in-depth and provide detailed steps for fixing them. We also discuss different causes of the car shaking when the AC is turned on in order to help you identify what may have caused it in your own situation.
Causes of Car Shakes When AC Is On
Car shakes when Ac is on can be a frustrating and hazardous problem for drivers. Knowing the potential causes of this issue can help quickly identify and resolve the underlying cause to reduce any further damage to your vehicle’s components or performance. Though it can be difficult to determine what exactly is causing the shake, understanding what could be responsible can help you fix the problem in no time.
Clogged air filter
One of the primary causes of your car shaking when you turn on the AC could be a clogged air filter. Since the AC draws in outside air for cooling, the filter catches any dust or debris, preventing it from entering your system. Over time, this build-up can cause the filter to become clogged, leading to your car shaking.
Replacing or cleaning the air filter is an important part of regular maintenance and should be done every 5,000 to 10,000 km, depending on road conditions and if you’re using factory-installed parts. A clogged air filter can have more effects than just causing car shakes—including reduced fuel economy and performance—so make sure to check it regularly if you want to get the best out of your vehicle!
Low engine oil level
Another one of the most common reasons for your car to shake when the AC is on is a low oil level. Frequently, low engine oil reduces pressure in the system, causing many components to quiver and shake. If you have an older car model, it can get worse if the constant running of the air conditioning causes too much stress on the engine.
Simply dip a dipstick into your car’s oil reservoir to check if this is your problem. Ensure enough oil keeps your engine running smoothly and safely before turning on the AC.
Malfunctioning AC compressor
An AC compressor works to reduce stress on your engine by compressing and pumping the refrigerant through the system. When faulty, it can cause vibrations that get transferred into your car, resulting in shaking when the AC is turned on. It’s important to get this problem fixed as soon as possible because not only will it be uncomfortable to drive in, but continuing to use a bad compressor can cause extensive damage to your car in the long run.
Faulty transmission system
Issues with the transmission system can be one of the causes of your car shaking when the AC is on. Often, the engine mounts that secure the vehicle’s transmission to its chassis become loose or damaged. This can cause vibrations when you try to turn on or off your air conditioning system. In addition, if the drive shaft or motor mount supports are worn out, this could be contributing to your car’s shaky condition.
Outdated spark plugs
Spark plugs, crucial components of your car’s engine, age slowly and eventually lose their efficacy. While newer spark plugs provide a powerful and clean spark for combustion, older ones tend to misfire, causing your car to shudder or shake. If your car’s spark plugs are overdue for a change, it could be the root cause of your problem.

Faulty fan belt tensioner or pulley
If your car shakes, wobbles or vibrates when the air conditioning (AC) is running but not at other times, it might be an issue with your fan belt tensioner or one of its pulleys. The AC compressor is driven by a fan belt, often called a serpentine belt, powered by the engine, and the tensioner maintains enough tension on the belt so that it doesn’t slip off. If the tensioner or one of the pulleys connected to it has gone bad, then it can cause the car to vibrate when the AC is in use.
Loose or Disconnected Hoses
Finally, your car may be shaking when the AC is on due to a loose or disconnected hose. The hoses connected to the AC are responsible for allowing coolant and refrigerant to flow from the compressor through the condenser and back into the engine. If your vehicle’s hoses aren’t connected properly, they can become disconnected while the car is running, which causes vibrations and shakes.
It’s important to check these connections right away and make sure all of your hoses are firmly attached. A damaged hose can impact the AC’s performance, resulting in decreased air output and reduced air temperatures. Taking care of any broken hoses quickly not only helps keep your car running smoothly but also keeps you from sweating too much on hot days.
Steps To Fix The Issue
If your car is shaking when the AC is on, there are a few steps you can take to help resolve the issue:
- Check your oil level – ensuring that it’s at an optimal level can help reduce vibration and shakes.
- Have a technician inspect your AC compressor – they’ll be able to tell if it has any faults or needs replacing.
- Inspect your transmission system – if any of the engine mounts, drive shafts or motor mount supports are worn out, then these should be replaced.
- Change spark plugs as needed – older spark plugs cause misfires which result in vibrations and shakes in cars with air-conditioning systems running frequently.
- Replace faulty fan belt tensioner or pulleys – if these components have gone bad, then it can cause the car to vibrate when the AC is in use.
- Check your hose connections – make sure that all of your hoses are connected properly and firmly attached.
Taking care of these issues as soon as they arise will not only give you a more comfortable driving experience but also help prevent any further damage to your vehicle in the long run. With proper maintenance, you can ensure that your car runs smoothly whenever you turn on its air-conditioning system.
