Is the power running board on your SUV not working anymore? This motor assembly with bracket is designed to replace the faulty unit on the left (driver's) side. It fits a bunch of popular GM full-size SUVs and trucks from the 2007-2014 model years, including the Cadillac Escalade ESV/EXT, Chevrolet Tahoe, Suburban, Avalanche, and GMC Yukon/Yukon XL. It references OEM part numbers 19303235 and 22778156. Before you buy, it's super important to compare your old motor and bracket with the product photos and check your vehicle's exact year and model to confirm compatibility. This should get your automatic step extending and retracting smoothly again. A common fix for a convenient feature that tends to wear out over time.
