Q: Putting on ac or heat screaming noise

asked by on

Putting on ac or heat for about 5 min a loud screaming noise

My car has 80000 miles.
My car has an automatic transmission.

The noise is most likely coming from the a/c blower inside the right side of the dash. The bearing inside the blower motor is noisey. Verify the noise is coming from the a/c blower motor and replace the blower motor.
