most likely your air conditioner needs recharged per my mechanic brother-in-law
It is probably the sound of the defroster fan.
See if power is getting to fan motor--connect a test light and turn on A/C or defroster--if getting power to motor. Then motor is bad. If not getting power to fan-- Check fuse Check relay See if power is getting to fan motor--connect a test light and turn on A/C or defroster--if getting power to motor. Then motor is bad.

Check that the wire on the rear defroster is connected to the defroster. If broken off repair it.
you have to make sure there is no short and check for voltage amount at the strips of the window to make sure defroster is working
Do you mean the defroster fan? If so yes if it blows the main engine circuit breaker in the fuse block.
Which fan is not working? Engine fan or HVAC fan?
The defroster turns the AC compressor on so if the vehicle runs hot with the AC on it will also do so with the defroster. To fix this look first to see if your Ac fan motor is working. On this year model I believe there are two different cooling fans, 1 for the motor and the 2nd for the air conditioner. A lot of times it may just be a fuse or maybe even a relay. Anyhow, start there.
Not enough info, please ask a new question and include year, make, and model.
If the AC or Defroster is on, many vehicles will also turn on the cooling fan.
Cooling fan? will only come on when: vehicle temp exceeds 235o F or when a/c or defroster is activated
