Why is the car AC not blowing air but making loud noise?
1 Answers
The reasons why the car AC is not blowing air but making loud noise include: 1. Check whether the air outlet switch is properly connected and if there is any short circuit; 2. Check whether the AC fuse is burnt out; 3. Check whether the AC air outlet is blocked; 4. Check whether the AC motor blower is working normally; 5. Check the vehicle's power distribution and the battery level. The principle of AC air blowing: The AC blower draws air into the vehicle, which flows through the air ducts inside the car. There are dampers in the air ducts, and the AC air volume is adjusted by controlling the blower speed and the opening/closing of the dampers. The car AC refers to the air conditioning device installed in the car, which can cool, heat, ventilate and purify the air in the cabin.
