This little guy controls the speed of your blower motor – that’s the fan that pushes air through your vents when you’re running the heat or A/C. It doesn't make the air blow, it just lets you adjust how much air comes out. It does this by creating electrical resistance, basically slowing down the power going to the fan. It has a few different resistance levels, that's how you get low, medium, and high fan speeds. It sits between your A/C control panel and the blower motor itself. When you turn the fan speed knob or use the controls on your dash, the signal goes through this resistor to tell the motor how fast to spin. It’s a pretty simple component, but it’s crucial for comfort inside the car. Without it, you’d likely only have one fan speed – usually high, and that would get old quick. If this resistor fails, you’ll usually notice it because you start losing fan speeds. Often it’ll start with just the high speed working, then eventually you might lose everything. Sometimes you’ll notice only certain speeds work, or the fan will only work intermittently. It’s one of those things that isn’t immediately dangerous, but makes driving uncomfortable. We carry these pretty regularly, and you can often find a good one at places like Fixparts Online. It’s usually a fairly straightforward repair, but it’s always a good idea to get a new one if your fan speeds are acting up. Durability you can trust: A/C Blower Motor Resistor (MPN ABR18000P) has a 12-month warranty!
