If your motor only works on low speed and not on high speed first check to see if you have the proper voltage to high speed. Check with a voltmeter or multimeter, check from common on the motor to high speed on the motor at the switch. If you have the proper voltage then you have an open winding on high speed and the motor needs replaced. If you don’t have the proper voltage or any volts, then the switch is bad and needs replaced. This also will be the same if, medium speed won’t work and low speed does.

It more than likely has the bearing or bushings worn. Usually better just to take the motor out and get a new one unless there is a place that can replace bearings nearby. This kind of repairman is very few and far between.
