Why does the CRV shake when the air conditioning is turned on?
2 Answers
Here are the reasons why the CRV shakes when the air conditioning is turned on: 1. Carbon buildup: As the vehicle accumulates mileage, carbon deposits can form in multiple areas, especially in the throttle body. 2. Normal vibration: The engine naturally vibrates during normal operation (including after starting the compressor), but some of this vibration is filtered out by the engine mounts. Below is additional information on the differences between the CRV and XRV: 1. Vehicle class: The CRV is a compact SUV; the XRV is a subcompact SUV. 2. Powertrain: The CRV uses two engines—a 2.0L naturally aspirated engine and a 1.5L turbocharged engine; the XRV also uses two engines—a 1.5L naturally aspirated engine and a 1.5L turbocharged engine. 3. Dimensions: The CRV measures 4585mm in length, 1855mm in width, and 1679mm in height, with a wheelbase of 2660mm; the XRV measures 4328mm in length, 1772mm in width, and 1605mm in height, with a wheelbase of 2610mm. 4. Rear suspension: The CRV uses a multi-link independent suspension; the XRV uses a torsion beam non-independent suspension.
When I turn on the air conditioning in my CR-V, the car shakes. This is commonly caused by unstable engine idle speed, as the additional load from the AC compressor increases the burden. The compressor is driven by the engine, and if the idle speed is too low or there is excessive carbon buildup, the idle will fluctuate. A loose belt can also slip, causing vibration noises and intensifying the shaking sensation. When the refrigerant is insufficient, the compressor works harder, increasing the risk of vibration. Worn or aged engine mounts can amplify the shaking effect. Long-term neglect of these issues may lead to engine damage or increased fuel consumption. I recommend checking whether the idle speed stabilizes around 800 RPM when parked, listening for any abnormal noises. If the issue persists, promptly visit a professional shop to inspect the compressor system. Cleaning the throttle body or replacing the belt can significantly improve the situation.
