What would cause a 2007 Toyota tundra noise evaporator blower in low speed?

A noise from the evaporator blower in a 2007 Toyota Tundra at low speed could be caused by several factors, including debris or foreign objects lodged in the blower motor, worn-out bearings, or a failing blower motor itself. Additionally, a dirty or clogged cabin air filter can restrict airflow and cause the blower to make unusual sounds. It's advisable to inspect the blower motor and associated components to identify and address the source of the noise.
