Is the airflow from your vents weak, noisy, or not working at all? It's probably your blower motor. This GVPART4U replacement is a direct fit for the OEM part numbers 22741027, 1581683, and 700164. It's specifically designed for a wide range of GM trucks and SUVs from the 2007-2014 model years. This includes the Chevy Tahoe, Suburban, Avalanche, and Silverado 1500/2500HD; the GMC Yukon, Yukon XL, and Sierra 1500/2500HD; and the Cadillac Escalade, ESV, and EXT (even the 2009 Hummer H2). PLEASE double-check your specific year, make, and model using the Amazon Fitment tool or your vehicle's manual before ordering. This motor is what powers the fan that pushes hot or cold air through your dashboard vents. Signs you need a new one include: little to no airflow, the fan only working on certain speeds, loud squealing or rattling noises from the dash, or a burning smell. This upgraded unit is built to be more efficient, quieter, and longer-lasting (rated for 80,000+ hours). It comes with the fan cage already attached, which can make installation easier. The packaging is secure to prevent damage. Includes a 1-year warranty. Recommended for DIYers with some mechanical experience, as dash disassembly is usually required. Fix your cabin comfort and get your AC/heat blowing strong again!
