Blower Motor Resistor | 1999-2014 Chevy Silverado GMC Sierra Avalanche Escalade | OEM 15305077

Your Chevy or GMC’s blower fan works on some speeds but not others — or only blows on the highest setting. On 1999–2014 GMT800/GMT900 trucks and SUVs, this is the classic sign of a failed blower motor resistor. The resistor controls fan speed by regulating voltage to the blower motor. When it fails, certain speeds drop out entirely. This is the direct-fit aftermarket replacement.
