Blower Motor
WARNING: This page is about a different car, the 2006 Ford Pickup, 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The 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 4 speeds and is controlled by the blower motor switch and resistor (manual systems) or the EATC module and blower motor speed control (EATC systems).
