What Causes the Car to Shake When the AC (air conditioner) is Turned on?
your vehicle shakes when the air conditioner is turned on, it's an indication
that there's an issue that has to be addressed. The majority of people believe
that this occurs only when there is a problem with the AC compressor. However,
it might be the consequence of a number of factors, which we will address later
in this article. To fully comprehend this, you must first learn the names of
the engine components and how they interact with the AC compressor.
vehicle's air conditioner compressor is an essential component. In hot weather,
it cools the inside air of a car, creating a comfortable atmosphere for the
passengers. With this knowledge, you'll be able to predict when AC systems may
fail and how to avoid them.
this post, we'll look at why the car shakes when the air conditioner is turned
on and how to remedy the problem. If you're still not sure, look for full car service near me online and talk to a competent technician at a respected
When the air conditioner is turned on, what causes the car to shake?
new vehicles come equipped with air conditioning. The air conditioner serves
two purposes. The first option is to increase the refrigerant pressure. For
heat transfer to occur, the refrigerant must be hotter than the ambient
evaporator's second job is to maintain low pressure. This allows the
refrigerant to evaporate and absorb heat energy from the cab of the car. It
also circulates the compressor oil and refrigerant, which mix and circulate
throughout the air conditioning system. Here are some of the reasons why your
vehicle shakes when the air conditioner is turned on:
1. Engine Load
The air conditioner
functions as a miniature engine, putting undue strain on the engine. When you
switch on the air conditioner, the car engine activates components like the
idle speed or the air control motor. By compensating with an extra drag, you
may raise the idle compressor. When the air conditioner is turned on, the car
shakes due to the inaccuracy in this operation. When the air conditioner is
turned on, the added drag might cause the steering wheel to shake. When the AC
is turned on and the steering wheel is turned, the possibilities of the engine
stopping rise. If the air conditioner continues to overload the engine, some
engine parts will wear out and need to be replaced. Search online for car service near me and book your car in with a qualified car mechanic to
diagnose and repair the issue.
2. Engine Mountings/Foundation
The engine mountings secure the suspension and engine. The
engine and transmission are held in place by the mounts, which keep the engine
and transmission at the proper suspension angle. The mounts are put under a lot
of stress when you switch on the AC. As a result, when the engine mounts or
foundations wear out, vibrations and rattles occur when the air conditioner is
turned on. If the engine mount is damaged, vibrations and sounds will become
more noticeable. As a result, if you start to feel vibrations, contact your
technician to see if the mounts are in good working order or if they need to be
3. Faulty Throttle Position Sensor
A faulty TP sensor is another reason why the vehicle shakes while
starting. The RPMs are not controlled by a malfunctioning TP sensor. As a
result, the car will shake if you turn on the AC when the RPMs are uneven.
You'll need to clean or replace the sensor to fix this problem.
4. Faulty Fuel Injector
The fuel injector
delivers the correct amount of fuel to the engine at the proper moment. If the
fuel injector fails, the engine will not get enough fuel, decreasing its
performance. When the air conditioner is turned on, the engine is put under
even more pressure, and the car begins to vibrate. If the vibrations are caused
by this, the fuel injectors will need to be changed.
5. Old or Damaged Spark Plugs
your vehicle shakes when the air conditioner is turned on is a faulty or
outdated spark plug. A lack of connection during the early electricity
generation is the reason of this. It's possible that this is due to a single
worn-out or damaged spark plug.
6. Faulty AC Compressor
Another common cause of
car shaking when accelerating is a malfunctioning AC compressor. Damaged air
conditioning exerts an excessive demand on the engine, causing huge vibrations.
Accelerate the car while the air conditioner is on to diagnose this. You should
replace the AC if you notice a difference in the pick.
