Help keep your heater and A/C fan responding to every speed you select with the Four Seasons HVAC Blower Motor Resistor / Switch, part number 20277, the Maxima switch built for the blower circuit. It is a direct-fit replacement for the 2000-2004 Nissan Maxima. See the "Vehicles it fits" section for engine-level details.
This resistor sits in the blower motor circuit and helps regulate the current reaching the blower motor, so the fan can run at the speeds chosen on the climate controls. Four Seasons describes it as an HVAC blower motor resistor, and the catalog lists it as a switch, so you will find it under both names.
- Vehicle-specific application: built for the listed vehicles.
- Precision engineered: engineered and tested by Four Seasons, which brings more than 50 years of mobile A/C experience.
- Quality contacts: designed for proper conductivity in the blower circuit.
- OE-style connectors: for connection to the vehicle's blower circuit wiring.
Signs this part may need replacing include a blower that runs on only some speeds, only on high, or not at all. A failed blower motor, control switch, fuse or wiring fault can cause similar symptoms, so diagnose the circuit before you replace the resistor.
