Car owners, if your blower motor is acting up, this resistor could be your fix! This AITKEN blower motor resistor is designed to replace the OEM part in several Ford and Lincoln vehicles. When these resistors go bad, you might notice your fan only works on certain speeds, makes weird noises, or stops working entirely. This little component regulates the current to control your blower motor speed, which means it directly affects your ability to adjust air volume and temperature in your cabin. Compatible with Ford F-150 models from 2004-2008, F-250/F-350 Super Duty, Freestar, Thunderbird, Lincoln LS and Mark LT, and Mercury Monterey from those same years. The installation is usually pretty straightforward - it's typically located below the passenger side console near the blower fan. This aftermarket part is heat-resistant and corrosion-proof, with 100% testing to ensure it performs like the original. We include a one-year free replacement policy, so if you get the wrong part or it stops working, we'll send you a new one no questions asked.
