Connect your wiring harness to the fan that moves heated and cooled air through the cabin with the Standard Ignition Blower Motor Connector S-581. This electrical plug links the vehicle harness to the front blower motor. It is a direct-fit replacement for the listed applications, including the 1980-2000 Ford F-150, 1994-2008 Ford Mustang and 1991-1999 Ford Explorer. It also covers many more Ford, Lincoln, Mercury, Mazda, Jaguar and Buick models. See the Buyer's Guide tab for the full list and engine details.
The blower motor connector carries current from the harness to the blower motor. Over time, heat can melt or burn a connector, and its terminals can corrode or loosen. Signs this part may need replacing include a melted or discolored plug, corroded or loose terminals, or a blower that works only intermittently. If a damaged connector is the cause, S-581 replaces it. Diagnose the circuit first, because a blower motor, resistor or control switch can cause similar symptoms.
