2. Faulty compressor: If the compressor is not working properly, it can also cause shaking. The compressor is responsible for circulating the refrigerant throughout the AC system, and if it is not working properly, it can cause the system to malfunction and cause shaking.
3. Faulty clutch: The clutch is responsible for engaging the compressor with the engine, and if it is not working properly, it can cause shaking.
4. Faulty drive belt: The drive belt is responsible for connecting the compressor to the engine, and if it is not working properly, it can also cause shaking.
5. Vacuum leak: A vacuum leak in the AC system can also cause shaking. A vacuum leak can cause the system to lose pressure, which can lead to shaking.
6. Faulty expansion valve: The expansion valve is responsible for controlling the flow of refrigerant into the evaporator, and if it is not working properly, it can cause shaking.
7. Faulty evaporator: The evaporator is responsible for absorbing heat from the air inside the car, and if it is not working properly, it can cause shaking.
8. Faulty condenser: The condenser is responsible for dissipating heat from the AC system, and if it is not working properly, it can cause shaking.
Note: If your car is shaking when the AC is on, it is important to have it inspected by a qualified mechanic as soon as possible to determine the cause and have it repaired if necessary.
