Review on HVAC Blower Fan Resistor Harness Kit - Compatible with Manual AC Controls in Chevy, Cadillac, GMC Vehicles - Replaces 22807122, 15305077, 973409 - Ideal for Escalade, Avalanche, Silverado, Tahoe, Sierra, Yukon Models by Tio Kotaki

def Does NOT fit my Sierra. not even sure what they sent but after visiting NAPA and buying the correct one ($3 more and actually $4 less at Advance and Autozone) we pulled a bundle from stock and none fit or fit at all. fit and all fan speeds worked except #5, but the mounting tabs were badly torn, misaligned in weird places, and no mods were able to install it. You can get this part with a 2 year warranty for $18 from Autozone or Advance and $24 from Napa (10% off codes), a waste of time for me. I'm sure it will fit other models, but you won't save money by buying this one.
