Review on HVAC Blower Motor Resistor Kit with Harness for Chevy Silverado Tahoe Trailblazer Suburban Avalanche GMC Sierra Envoy Yukon Buick Cadillac Escalade & more - Replaces #15 81773, 89018778, 89019351 by Michael Mendoza

I am very satisfied with this part. for my 2006 Chevrolet Avalanche. with automatic air conditioning. After identifying the problem with the old fan resistor through YouTube videos, I ordered this one. It was the perfect match. It takes less than 30 minutes to remove the old part and install the new one. I note that there were no instructions in the box, but there was an excellent video on the company's website (on Revain). Also, there was no shrink tubing in my box. I didn't need them as the previous owner of my car had already replaced the unit and I was able to use the working wiring harness that was previously fitted. This part was very cheap compared to GM or an auto parts store.
