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 Adewole Sherman

Ideal for 2002 Silverado 2500hd with extended cab without automatic climate control. There was some confusion as to whether I needed the 2 or 4 mounting hole version, but 2 was correct. A screw was badly rusted and had to be loosened with a vice. Ideal replacement for silicon based resistors that should last longer. The first lasted 19 years, I hope I don't have to do it again. Came with a fatiguing harness that can be cut and spliced if the connector melts, common but not my cup of tea. Excellent quality, I will use this company again if I need other similar parts. The only problem was the screws holding it in place, one was rusted and I had to use a vise to get it out and the harness connector clip was pointing the other way so I had to turn the original harness up against the way it was before was, had to bend . never mind
