Blower Motor
WARNING: This page is about a different car, the 2003 Ford Pickup, 2003 Ford F550 Super Duty, 2003 Ford F450 Super Duty, and 2003 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.
The A/C blower motor pulls air from the air inlet and forces it into the plenum assembly where it is mixed and distributed. The A/C blower motor has four speeds and is controlled by the blower motor switch and resistor (manual systems) or the EATC module and blower motor speed control (EATC systems).
