Duralast HVAC Blower Motor Resistor JA1717

The HVAC blower motor resistor or BMR for short, controls the speed of vehicles blower motor. A malfunctioning blower motor resistor will cause a poor cabin cooling or heating condition. It can also cause poor windshield defrosting or de-icing, reducing driver visibility. The blower motor should be checked for amperage draw per the manufacturer's specification and cabin air filters, if equipped, should be replaced. Duralast products are designed and tested to OE specifications for a direct-fit, easy install. Duralast engineering delivers trouble-free operation, optimum performance and a long service life.
