Beck/Arnley HVAC Blower Motor Resistor P/N:204-0021
Restore your fan's full range of speeds with the Beck/Arnley HVAC Blower Motor Resistor 204-0019. This resistor sits in the blower motor circuit and adds resistance to step the fan through its lower and mid-range settings, letting the climate controls deliver more than just the high-speed blast. It's a direct-fit replacement for the 1999-2003 Mazda Protege and 2002-2003 Mazda Protege5.
If a failed resistor is the reason your blower only runs on the highest setting or has lost one or more fan speeds, this is the component that controls those steps. Diagnose the cause before replacing, as blower faults can also stem from the switch, wiring, or motor.
