How to Change Blower Motor Resistor on 2002 Ford Taurus


The blower motor resistor on the 2002 Taurus governs the speed of the fan. It has three springs that are of different thickness, for low, medium and high speeds. If the resistor is bad, not all speeds will work. The switch should be tested prior to replacing the resistor to ensure that the switch isn’t bad. The symptoms of both are the same, unless the switch doesn’t work at all. Though the blower motor resistor could completely fail and cause all speeds to not work, this seldom happens.

Tools Used: Tools, Flashlight, Set of sockets, Screwdriver

Change Blower Motor Resistor

Pull the instrument panel insulator off the bottom of the dash on the passenger’s side of the vehicle. Use a flashlight to look up under the dash for the blower motor resistor located close to the fan. Unplug the wiring harness connector. Use a screwdriver or socket, depending on the type of retaining screws or bolts, to remove the four retainers.

Pull the blower motor resistor out of the vehicle. Slide the new blower motor resistor into place and reinsert the retaining bolts or screws. Tighten the bolts or screws firmly. Plug in the wiring harness connector. Snap the instrument panel insulator back into place.
