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.OEM Cross-Reference: 15305077, 22807122, 89019089 | SKU: 220-6211Fits: Cadillac: Escalade, Escalade ESV, Escalade EXT (2002–2014) Chevrolet: Avalanche 1500/2500, Silverado 1500/2500/2500 HD/3500, Suburban, Tahoe (1999–2014) GMC: Sierra 1500/2500/2500 HD/3500, Yukon, Yukon XL (1999–2014) Why replace it?
