Help the front heater and A/C blower run at each speed you select with the Four Seasons HVAC Blower Motor Resistor / Switch, part number 20158. The catalog lists it under both names, and this 4Runner switch is a direct-fit replacement for the 1996-2002 Toyota 4Runner. See the Buyer's Guide tab for engine details.
A blower motor resistor works with the fan speed control. It lowers the voltage sent to the blower motor, which provides the reduced fan speeds. Four Seasons engineers and tests its products with trouble-free operation in mind.
- Quality contacts: designed to provide proper electrical conductivity.
- Precision engineered: backed by more than 50 years of Four Seasons mobile A/C experience.
- OE-style connectors: for connecting to the blower circuit wiring.
- Front position: cataloged for the front HVAC system.
This part may need replacing if the blower runs only on high, if one or more fan speeds no longer work, or if there is no airflow on the lower settings. A failed fan switch, damaged wiring or a worn blower motor can cause the same symptoms, so diagnose the circuit first. If the resistor is the cause, this unit replaces it.
