Take charge of the heater and A/C fan speeds in your 1990-2005 Mazda Miata with the Four Seasons HVAC Blower Motor Resistor, part number 20177, a direct-fit replacement for the listed applications. The blower motor resistor sits in the blower circuit and limits the current sent to the blower motor, which lets the fan run at the lower settings instead of only at full speed. Our catalog also lists this part under the Switch category.

  • Precision engineered: Engineered with precision for its role in the vehicle's blower circuit.
  • OE-style connectors: Connects to the blower circuit wiring through OE-style connectors.
  • Quality contacts: Designed to ensure proper conductivity.
  • Four Seasons experience: The brand brings more than 50 years of mobile A/C experience, and its products are engineered and tested.

Signs this part may need replacing: a blower that runs only on its highest setting, or one or more fan speeds that no longer work. The blower switch, wiring, fuse or motor can cause similar symptoms, so diagnose the circuit before replacing parts. If a failed resistor is the cause, the Four Seasons 20177 replaces it. See the Buyer's Guide tab for complete application details.
