Why does my car shudder when the AC is turned on?
Common Causes:
- Malfunctioning compressor: The compressor is responsible for compressing the refrigerant to create the cooling effect. If it's malfunctioning, it can cause the engine to vibrate and shudder.
- Weak serpentine belt: The serpentine belt drives the compressor and other components. A weak or loose belt can slip, causing the compressor to engage intermittently, resulting in shuddering.
- Clogged condenser: The condenser is located in front of the radiator and helps dissipate heat from the refrigerant. A clogged condenser can restrict airflow, reducing the efficiency of the AC system and leading to shuddering.
- Leaking refrigerant: Refrigerant is essential for the AC system to function. If there's a leak, the system may not produce enough cooling and cause the engine to compensate by working harder, resulting in shuddering.
- Damaged AC clutch: The AC clutch engages and disengages the compressor from the engine. A damaged clutch can cause the compressor to engage abruptly, causing sudden shuddering.
