Help your heater and A/C fan run at the speed you select with the Four Seasons HVAC Blower Motor Resistor / Switch 20407, a direct-fit replacement for the 2006-2009 Mazda 3, 2006-2009 Mazda 3 (Model) and 2009 Mazda 3 Sport. The blower motor resistor works in the HVAC blower circuit, changing the resistance in that circuit so the blower motor can run at different speed settings. This part is listed under both names, HVAC blower motor resistor and switch.
- OE-style connectors: fitted with connectors styled like the original equipment.
- Quality contacts: designed for proper conductivity through the circuit.
- Precision engineered: Four Seasons describes the construction as precision engineered.
- Vehicle-specific applications: cataloged as a direct-fit replacement for the listed applications.
Behind this Four Seasons switch is more than 50 years of mobile A/C experience, and the brand engineers and tests its products.
Signs this part may need replacing include a blower that runs only on its highest setting, or one or more fan speeds that no longer work. If a failed resistor is the cause, this part replaces it. Diagnose the blower circuit first, since a fan control, blower motor or wiring fault can cause similar symptoms. See the Buyer's Guide tab for complete fitment details.
