Is the fan in your Ford only working on high speed, or maybe not at all? Chances are, it's the blower motor resistor. This is a direct replacement part that controls the fan speeds in your vehicle's heating and AC system. It's a 100% new, high-quality part that matches OEM standards. It directly replaces part numbers YH-1715, 3F2Z-18591-AA, 973-444, and RU-440. Fits a ton of Ford, Lincoln, and Mercury vehicles! That includes: Ford Escape (2008-2012), Expedition (2007-2017), F-150 (2004-2014), F-250/350/450/550 Super Duty (2008-2010), Mustang (2005-2009), Lincoln Mark LT (2006-2008), Mercury Mariner (2008-2011), Montego (2005-2007), and a few others – check the full list to be sure. Before you order, please double-check your vehicle's year, model, and the original part number. Also, it's a good idea to peek at the old resistor before buying – count the pins on the connector and compare it to the photos to ensure it's the right shape. Installation is usually pretty straightforward – it's typically located on the lower passenger side dash behind the glove box area. Just a few screws to remove, swap it out, and plug it back in. A pro tip: while you're in there, if there's a lot of dust, consider cleaning the blower fan itself with a proper motor cleaner (don't use water!). This is a way more affordable fix than going to the dealership.
