Why is fan loud when air or heat is on?
The electric fans used to cool the engine are designed to switch on to full speed when the air conditioner compressor is being used. When you turn on the heater/defroster the air conditioning compressor also turns on to help remove moisture from the air. Since both when heating or cooling your car the air conditioner compressor is working the fan will be running at high speed and makes more noise.
