Why Does the Geely Emgrand's Air Conditioner Make Abnormal Noises?

[Kaden]

Geely Emgrand's air conditioner makes abnormal noises due to seat vibrations caused by operation. Reasons for abnormal noises when the heater is turned on in the new Geely Emgrand: If there are abnormal noises when the heater is turned on, it may be due to the need to replace the air filter, a broken blower, or foreign objects in the pipes. When these issues occur in a car, it is essential to promptly inspect and repair them. Solutions for dashboard noises: This is actually a resonance phenomenon when the car is idling. The abnormal noise is likely caused by plastic components, such as clips, being affected by idle resonance. This phenomenon often occurs or disappears due to the thermal expansion and contraction of plastic component gaps with seasonal changes.

I've encountered many Emgrand owners reporting abnormal noises from their air conditioning systems. The most common issue is leaves or debris stuck in the blower fan blades, creating a rattling sound like small stones hitting glass when the AC is turned on. Another frequent problem is aging AC belts, especially in vehicles over five years old, where the belt squeals noticeably during cold starts. The most concerning issue is compressor noise - a buzzing sound with metallic grinding usually indicates bearing failure, and if not repaired promptly, it may lead to complete failure. I recall a case last year with a ticking sound that turned out to be a loose AC line bracket. My advice is to first check the blower fan yourself for unusual noises, but for other issues, it's best to take the car directly to a repair shop - this isn't money you should try to save.

It's really annoying to suddenly hear strange noises from the air conditioning while driving an Emgrand. From my repair experience, there are several scenarios: a high-pitched whistling sound often indicates a reversed AC filter or air leakage from the damper; a creaking noise is usually caused by sand in the blower bearing; while a tractor-like clunking sound suggests compressor issues. Simple DIY checks include: after turning off the engine, reach behind the glove compartment to check the blower fan for leaves; also inspect the belt for cracks. However, if the noise changes with RPM, visit a mechanic immediately. Last time I encountered an owner who ignored it, ending up spending extra 2000 yuan on a compressor replacement.

I've disassembled dozens of Emgrand air conditioning systems with abnormal noises, so let me share some practical insights. The most common culprit is the blower fan, especially when leaves stick to the blades after car washing - it sounds like bouncing marbles when rotating. Compressor failures often show warning signs, such as suddenly louder clicking noises at red lights. Some cases involve loose AC pipes that clank against the frame on bumpy roads. I recommend starting with three actions: replace the cabin air filter, clean the blower fan, and tighten pipe clamps. These three steps can resolve 60% of abnormal noise cases. For the remaining issues, you'll likely need to remove the center console.

Last time I drove my friend's old Emgrand, the AC suddenly screeched so loudly that everyone in the car covered their ears. Experience tells me that this kind of intermittent screaming is mostly caused by insufficient refrigerant leading to expansion valve whistling. If it's a continuous roaring sound, it's basically the compressor clutch slipping. The most annoying thing is the strange noise from a new car, which is likely due to the assembly worker forgetting to install the vibration damping rubber pad during production. If you want to handle it yourself, try turning the AC to maximum airflow and blowing hard for three minutes—sometimes the stuck flap motor can reset. However, don't bother with metal friction sounds; worn compressor bearings must be replaced.

As an auto mechanic, I've long mastered the tricks to fix the abnormal noises in Emgrand's air conditioning. Noises vary by location: a rattling sound from the dashboard usually means debris in the blower, a humming under the steering wheel indicates AC pipe resonance, and a ticking from the engine compartment typically points to compressor issues. Car owners can perform a simple test: repeatedly switch between recirculation and fresh air modes while the AC is on—if the noise disappears, it's likely the gear teeth of the air blend door motor are damaged. I remember fixing a car last year where the noise was actually caused by a clogged AC drain pipe, causing water to backflow into the blower. Always stay alert—if you notice abnormal noises, first turn off the AC and switch to recirculation mode to minimize damage.
