Keep fan-speed selection in your hands with the Standard Ignition A/C and Heater Blower Motor Switch, part number HS-457. It is the control you use to choose how hard the heating and air conditioning blower runs. It fits many vehicles, among them the 1998-2001 Nissan Altima, 1995-1999 Nissan Sentra and 1996-2002 Nissan Pathfinder. See the "Vehicles it fits" section for the full list.
A blower motor switch may need replacing if the fan runs on some speed settings but not others, if the blower does not respond when you turn the switch, or if the fan works only some of the time. A faulty blower motor, blower resistor or wiring can cause similar symptoms, so diagnose the cause before replacing the switch. If the switch is the failed part, HS-457 replaces it.
