Help your heater and A/C fan run at each selected speed with the Four Seasons HVAC Blower Motor Resistor / Switch, part number 20397, a 2003-2008 Mazda 6 switch built as a direct-fit replacement. The blower motor resistor works with the HVAC controls to regulate the current sent to the blower motor, which lets the fan run at its lower speed settings. The manufacturer calls it an HVAC blower motor resistor, and it is cataloged as a switch, so it is listed under both names.
- Quality contacts: designed for proper conductivity.
- OE-style connectors: fitted with OE-style electrical connectors.
- Vehicle-specific application: built for the 2003-2008 Mazda 6.
- Four Seasons know-how: engineered and tested by a brand with more than 50 years of mobile A/C experience.
Signs this part may need replacing: the blower runs only on its highest setting, one or more fan speeds no longer work, or the blower does not run at all. A fault in the blower motor, control switch, wiring or a fuse can cause the same symptoms, so diagnose the cause before replacing. If a failed resistor is the cause, the 20397 replaces it.
