Air Distribution
WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
Vehicles with trim have a vertical duct that supplies air to the integral headliner air conditioning duct. Air is supplied to the passengers through six adjustable registers. The heater floor duct is integral to the side trim panel and has four fixed registers for optimum heater air distribution. The trim panel connects directly to the auxiliary A/C-heater unit.
Vehicles without trim do not have overhead registers, heater floor ducts or registers. A unique A/C register is used to distribute air-conditioned air, and a heater outlet duct assembly distributes heated air.
