Blower Motor Resistor on 2006 Chevy Silverado 2500HD
Great fit, I ordered the wrong part and then from the video on A1 Auto they highlighted that the plug could also be the issue. I contacted customer service and asked for the part number. They promptly sent me the right part numbers and after ordering them I watched the video and was able to install within a week. Thanks A1 Auto for your product line and videos.

1A Auto is the best.
Seem to be exactly what I need. Just need to get the ambition to crawl under the dash to install it. Fast service is always appreciated dealing with 1A Auto and those replacement Videos are a real money saver to go along with the fair priced parts.

Can I purchase just the wiring harness?

How to order?
Be sure to take out the old one and match the photo. I initially ordered one that looked like the one for my 2004 Chevy suburban. There are at least 2 different parts that do the same thing with different mounting holes.
