Review on 🔥 Dorman 973-409 HVAC Blower Motor Resistor Kit: High-Performance Upgrade for Cadillac, Chevrolet & GMC Models by Kenkoy Braggs

My 2003 Silverado 2500HD Speed #5 started working intermittently and eventually stopped working. I removed the resistor to verify the part number before ordering. 15305077 which is intended to replace this part. The electrical part works fine but the mounting tabs were wrong. The adapter plate from the original didn't help either, since the position of the relay and connector is different. Both sockets were fine. I didn't want to wait for the right part or the hassle of sending it back and replacing it, so I made some mounting brackets. Not a big deal, but if you need a direct replacement for part 15305077, buy an AC Delco for just a few dollars more.
