Thus, here we are highlighting down with some of the main reasons to know that why your car shook when your AC turned on.
1. Excessive Load on the engine
AC compressor hence  put away the strain  on top of the engine and in this condition when the load goes just as above some level, then it would bring about some vibration in the car for sure. If the pressure continues to rise on, then certain parts of the engine will start wearing out as well. In some of the additional reasons, it would be adding away with the issue related to the cooling fan or some blockage in the AC system. If this happens, then you  can choose to take your car to the nearest AC technician.

2.Reason Of Engine Mountings/Foundation
The engine mountings hence on the whole hold the engine and the suspension all at one place. Each single of the mount will be playing the critical role just as to keep on with the transmission and driver on a site to uphold a proper suspension angle. The mountings hence bear away with so much of the pressure. As the AC is turned on,  then the mountings, on the whole, undergo additional strain due to large starting load. In this way, any issue inside the  mounts will be resulting in the appearance of the shakes or the vibrations too. The broken part of the mount will be leading to the increase of the wave and also the noises as especially when the compressor of AC puts pressure on the engine. Therefore, you should, therefore, check your mounts to resolve this critical issue.

3.Cause of Bad Throttle Position Sensor
A malfunctioning version into the TP sensor cannot control the RPMs, and this is the main reason that when AC turned on top of the RPMs does  not remain constant due to the purpose of the bad TP sensor. The car shakes with the medium of being the unstable RPMs. The sensor has to be set much cleaned or replaced to solve away with this issue.
4.Cause of AC compressor
One of the main reasons for the vibrations when AC is turned on is mainly because of the faulty compressor. The most accurate form of the  technique for this problem detection is all to do with the simple observation. You should think about as to try accelerating your car with the means of the AC on and off. You can also think about as to check by moving it with your hand. When you turn on the AC, then in that condition this type of compressor puts more load than usual.
