Why does the Nissan Sylphy's air conditioner suddenly stop blowing air?
2 Answers
Nissan Sylphy's air conditioner suddenly stops blowing air for the following reasons: Blower motor failure: As the core component of whether the air conditioner blows air or not, if the blower motor fails, it will definitely stop blowing air. The causes of blower motor failure may be damage to the internal coil due to overheating or capacitor failure. Car owners can judge whether there is a fault by turning the car's air conditioner speed and air volume to the maximum and listening to the sound of the blower motor. Air filter failure: The blockage of the air filter is the most common situation where the air conditioner does not blow air. The outside air will be filtered by the air filter before entering the car, and it will also absorb many impurities in the air, making it easy to get clogged. The air filter can be removed, and if it is not very dirty, use an air gun to remove the debris and then reinstall it to check the problem of the air conditioner vent.
I've experienced the situation where the Sylphy's air conditioning suddenly stops blowing air several times. After years of driving, I've found several common causes: the blower motor might be faulty and won't start at all; or a fuse could be blown - check the corresponding AC fuse in the front fuse box and try replacing it. A clogged air filter is another frequent culprit, as accumulated dust can block airflow, and it's easy to remove and inspect yourself. Poor contact in the control switch is also possible - try toggling it a few times to see if it responds. During summer heat, address this promptly before it becomes undrivable. Additionally, low vehicle battery voltage or power supply issues can affect AC performance - use a voltmeter for safer diagnosis. In summary, start with basic troubleshooting, and if that doesn't work, visit a professional repair shop.
