2013 F150 Limited heater blower motor makes aloud noise when I turn it up above speeds 1-2

Bearing within motor could be bad, The blades are plastic, then can wear causing it to hit cowl or vibrate excessively at high speed. Remove motor and inspect. If you purchase another motor bring the old one with you. Ensure the pitch on the new motor is in the same direction as the old one.
