Is the fan in your Dodge or Ram's AC/heater stuck on one speed or not working at all? Chances are you need a new blower motor resistor. This INFINAUTO part is designed to replace OEM numbers 4885456AA, 4885456AB, and 4885346AA, and it fits a range of vehicles including the Dodge B1500/B2500/B3500 (1997-1998) and the Dodge/Ram 1500, 2500, 3500, and Van models from 1999 to 2003. It's made from durable metal and plastic to resist corrosion and handle temperature changes. Installation is pretty straightforward if you're handy, but if you're unsure, it's always a good idea to consult a pro or a repair manual. The package includes one resistor. This is a non-OEM aftermarket part, but it's built to get your climate control blowing at all speeds again. Get back to comfortable driving!
