Why does the Baojun 510 air conditioning fan make abnormal noise?
4 Answers
It may be caused by foreign object friction. You can remove the air conditioning filter to check for any foreign objects inside. Here is some related information about the Baojun 510: 1. Exterior Features: In terms of design, the Baojun 510 adopts a very distinctive split-type headlight design. The LED daytime running lights are connected to the large front grille, while the headlights are positioned on either side of the grille. The rear features conventional halogen tail lights. The 2019 Baojun 510 comes with a redesigned front and rear appearance. It features a new high-gloss matrix grille paired with LED split-type headlights. The vehicle is equipped with newly styled wheels, and the rear lights adopt a sharp rotary design with LED tail lights. 2. Interior Design: Inside, the Baojun 510 CVT model offers a choice of Rhythm Red/Black or Modern Black/Brown interior color schemes, enhancing the sporty atmosphere to complement its sharp exterior design. The cockpit features LED backlit adjustable split-type instrument clusters and double-stitched sport seats, creating a dynamic and youthful driving experience. Additionally, the Baojun 510's center console operation area uses high-quality piano black panels for both touch and visual appeal. The function buttons feature innovative piano-key buttons and toggle lever designs, offering a more playful and engaging feel compared to conventional flat buttons and knobs.
My car is also a Baojun 510. Last summer, the blower made a constant buzzing noise when the AC was on. It might be due to loose or deformed fan blades, causing friction against surrounding structures during rotation. Another possibility is severe bearing wear or lack of lubrication, leading to rough operation. Dust buildup inside is also common, and stronger airflow can amplify vibrations and noise. Later, I disassembled and cleaned it myself, finding a lot of debris stuck inside—after cleaning, it became much quieter. If left untreated, the noise will only get worse and may even affect the AC’s cooling efficiency. I recommend inspecting the blower unit promptly to prevent minor issues from turning into major repairs. During routine maintenance, remember to clean the AC filter more often to reduce dust accumulation.
The abnormal noise from the Baojun 510's blower mainly stems from several mechanical issues. The fan blade design can sometimes be unstable, causing resonance noise during high-speed rotation. Aging or internal faults in the motor also lead to abnormal sounds. Bearing wear or lack of lubrication is another common cause, resulting in rattling noises during operation. Additionally, loose mounting brackets can transmit vibrations into the cabin, creating unusual sounds. Owners should regularly check the blower for dust accumulation or blockages, and cleaning the filter can help prevent such issues. If the abnormal noise persists, do not delay—visit a repair shop for adjustments as soon as possible. Prolonged neglect can increase power consumption, reduce air conditioning efficiency, and compromise driving comfort.
When I notice the fan making noise, I usually start by troubleshooting the issue myself. First, I turn on the AC to locate the source of the sound. If it's coming from the fan area, there might be foreign objects stuck in the blades, and cleaning them usually solves the problem. If not, I listen for any signs of bearing wear, then try adding some grease or replacing them if necessary. Finally, I check if the motor is aging or malfunctioning. Most of the time, simple fixes can eliminate the noise. If there's excessive dust buildup, regular cleaning of the fan unit is recommended. The Baojun 510 is prone to dust accumulation, so it's advisable to avoid muddy roads to keep it clean. Addressing issues early saves both hassle and money.
