Q: A/C compressor

Squealing noise when the heater or a/c is turned on

My car has 10300 miles.

Check the condition of the drive belt. If the belt looks cracked or worn, it may be slipping and making a squealing noise. Consider hiring one of our mobile experts to come out and offer a personal diagnosis of the noise. YourMechanic technicians makes house calls.
