2010 Toyota Prius front A/C has a loud whiny noise that gets louder as the A/C is increased. Seems to be coming from the center. Also, had some rattling in the past but now just a whine. A/C works fine. Battery is in good condition. .
Can I fix it myself?
Normally this is due to wearing of the blower motor. Suggest replace blower motor.
