Designed to regulate your heater and A/C blower's fan speeds, the Four Seasons HVAC Blower Motor Resistor / Switch 20133 is a direct-fit replacement for the 1989-1994 Nissan Maxima and 1990-1992 Nissan Stanza. See the "Vehicles it fits" section for engine details on each application.
The blower motor resistor works with the HVAC fan control to vary the current that reaches the blower motor, which is how the lower fan-speed settings are produced. This Four Seasons switch is cataloged under both the Switch and HVAC Blower Motor Resistor names, so you may find it listed either way.
- Engineered and tested: Designed and tested by Four Seasons, backed by more than 50 years of mobile A/C experience.
- Precision engineered: Made for its HVAC blower speed-control role.
- Vehicle-specific applications: Cataloged for the listed Nissan applications.
- OE-style connectors: Uses OE-style connectors for the electrical hookup.
Signs this part may need replacing: a blower that runs only on the highest setting, one or more fan speeds that no longer work, or no blower operation at all. These symptoms can have other causes, such as the blower motor, fan control or wiring, so diagnose the system first. If a failed resistor is the cause, this part replaces it.
