VERY loud noise soming from AC/heater fan area
I am getting a terrible noise from my AC/heater fan area of the dash. It is intermittent. It is a VERY loud noise. And I mean VERY loud. Changing the fan speed has no effect on the pitch of the noise. So it is not the rotation of the fan blade itself. I turn the fan off and the noise stops. Then it won’t make the noise for a few days.
