It regulates the blower motor's electrical resistance so the fan responds correctly to your climate controls; when the resistor fails, common symptoms include loss of some fan speeds, only one working speed, or no airflow from the vents. Ruizure builds this part with reinforced terminals and heat-resistant components and backs it with a two-year warranty.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this resistor fix my vehicle's fan speed problems?\u003c\/h3\u003e\n\u003cp\u003eReplacing a worn or damaged blower motor resistor typically restores the full set of blower speeds by reintroducing the correct resistance paths between the control switch and the fan motor.
