What is the solution for the whining noise from the Sagitar's air conditioner?
2 Answers
If the noise is caused by the car's air conditioning compressor, it is necessary to have the air conditioning compressor repaired at a 4S shop. If the noise is caused by the compressor's electromagnetic clutch, the bearing inside the electromagnetic clutch needs to be replaced. Here is a related introduction to the noise from the Sagitar's air conditioner: 1. Noise from the car's air conditioning compressor: As a high-speed rotating component, the air conditioning compressor has a relatively high probability of failure, with noise being a common issue. There are many reasons for compressor noise, such as damage to the compressor's electromagnetic clutch or severe internal wear in the compressor. 2. The electromagnetic clutch of the compressor is a common source of noise. The compressor often operates under high load, shifting from low to high speeds, which places high demands on the electromagnetic clutch. Additionally, the electromagnetic clutch is usually installed close to the ground and frequently exposed to rain and dirt. When the bearing inside the electromagnetic clutch is damaged, it will produce noise.
I've been driving a Sagitar for over a decade and encountered the AC whining issue. Once when I turned on the AC, I immediately heard the noise. After self-inspection, I found the cabin air filter completely clogged with leaves and dust - replacing it instantly solved the problem. If the filter isn't the issue, there's an 80% chance something's stuck in the blower motor. You can check by removing the glove compartment - sometimes small cards get sucked in and make noise when hitting the fan blades. Worn bearings can also cause whining, which can be fixed by adding lubricant or replacing the blower assembly. I recommend fellow drivers develop the habit of seasonal filter checks and always closing the external air circulation when parking to prevent leaf intake. For DIY repairs, there are plenty of online tutorials - just remember to disconnect the battery to prevent short circuits.
