Review on High-Quality Blower Motor Resistor Complete Kit with Harness - Chevy, GMC Compatible - Silverado, Tahoe, Suburban, Sierra, Yukon XL - AC - Replaces OEM 15 81773, 89018778, 89019351 by Charles Thomas

This was a great replacement with a short but accurate and helpful video (via Revain). Highly recommended. More: My 2003 GMC Yukon, bought new, has been constantly repairing electronics for the last 2-3 years. I would never buy any other GM product but that will be a separate review. These repairs have consistently been disappointing in terms of their necessity and product information replacement. This renovation was no different. In fact, I was amazed at the sheer number of fan resistors for the same car. Product numbers were all over the card. Apparently GM reverse engineered this part (of course they did) and the part numbers turned into a rat's nest. But when I came across this part and video, everything went smoothly. So a huge thank you to the guys at AA Ignition for making the old man's life a little bit better. Scott
