I fix the loud squealing heater fan/motor?

How do I fix the loud squealing heater fan/motor? Sometimes the squeal will stop for a while if the fan is run on high.

Sorry to have to tell you, but the noise you hear is the bearings in the motor going out. They are not serviceable, so the only fix is to replace the blower motor. Thanks
