but I hope you see this. The blower motor can cause a resistor to fail if
the motor is running at a higher than normal amperage. Typically what
causes this is either an old blower motor (so bearings and stuff internally
goes bad) or there is debris causing the motor to work extra hard to spin
(such as leaves. You can see in this video: How to fix a Loud AC, Heat Fan
(Blower motor) that there were leaves and stuff blocking the motor and the
actual motor itself sounded good and looked brand new inside.
