Proton persona sv 2014.

When on aircond, immediately u can hear the aircond fan is on, u feel slightly more vibrations.

Is it normal ? I remember when my car is new , the aircond fan is loud too, the radiator fan is very very much more quieter.

Any method to reduce the aircond fan noise and vibration ? Can I unplug it? There is still a backup radiator fan.

Unplugging it will risk overheating.

Could be a fan motor on its way out or it might be as simple as loose fan motor/fan shroud.

i think is the famous issue for persona and exora. From far i can tell ur ac is running. damn loud.. radiator fan doesnt differ much also. when the engine is too hot. system will still allow the fan to run after u off the engine.

On the up side, you get cold air.. no complaint on the ac temp right? brows.gif

all car like that . persona is best coz its uses 2 fan instead of one , if one broken another will support it. vibration coz engine mounting out and please service aircond not just clean filter change oil compressor . for your FYI exora and myvi more loud than persona

I just changed all 4 mounts , and I realised when I first get the car 5 years ago , it’s memang loud one and can feel slight vibrations. It’s the design fault I guess. I did further observation , the aircond fan is loud and vibrates more than the radiator fan , and the radiator is attached directly to the car frame without mounts and thus we can feel the vibrations in the car.

Try changing the radiator fan motor itself,maybe the bearings in the motor on its way out.my condensor fan vibrate too and have play on the fan.try test the blades,have play or not.

When only the radiator fan is running , not much noise n vibrations , when the aircond fan kicks in obviously noise started and more vibrations.

Actually I already let my foreman check, he say no prob at all, it’s the design fault , even some ppl change new set also same noisy and vibrations. I think I better give up lol. Unless I can do some custom modifications like adding mounts to the fan.
