Help your heater and A/C fan run at the speeds you select with this Four Seasons switch, the HVAC Blower Motor Resistor / Switch, part number 20122. It fits many vehicles, among them the 1987-1995 Nissan Pathfinder and the 1995-2010 Nissan Pickup, and is a direct-fit replacement for the listed applications.
A blower motor resistor sits in the blower motor circuit and varies the current sent to the fan, which produces the lower blower speeds. This part is listed under both names: Switch and HVAC Blower Motor Resistor.
- OE-style connectors: connections styled after the original equipment for the listed applications.
- Quality contacts: built to maintain proper electrical conductivity.
- Precision engineered: designed for vehicle-specific applications, not a universal fit.
- Four Seasons experience: engineered and tested by a brand with more than 50 years in mobile A/C.
Signs this part may need replacing include a blower that runs only on its highest setting, or one or more fan speeds that no longer work. A faulty blower switch, wiring or the motor itself can cause similar symptoms, so diagnose the circuit before replacing parts. If a failed resistor is the cause, this unit replaces it. If you are shopping for a 1987-1995 Nissan Pathfinder switch for the blower circuit, see the "Vehicles it fits" section for the full list of vehicles and engine details.
