When I turn the vent control to defroster the air continues to blow out of the ac vents. The heater and the ac both work fine. I just can't get the air to blow out of the defroster vents.
May be just a cable adjustment.
SECTION 412-01: Air Distribution and Filtering
2001 Focus Workshop Manual
DESCRIPTION AND OPERATION
Air Distribution and Filtering
The new heating and ventilation system ensures even air distribution.
The temperature control and air distribution flaps are controlled by two operating cables. All vehicles have a recirculated air function, with the flap controlled by a servo motor.
Air is supplied to the windscreen and side windows regardless of the air distribution setting.
The clean air filter is fitted as standard in most countries. This cleans the incoming fresh air of pollen and dirt particles. It must be renewed after every 40,000 km under normal operation conditions, or after 20,000 km under difficult conditions. If no clean air filter is installed, a plastic grille is fitted over the air intake. This can easily be replaced with a clean air filter.
Air distribution operating switch
Face level
The main flow of air enters the passenger compartment at face level.
Face level/floor level
The main flow of air enters the passenger compartment in equal parts at face level and floor level, and a small amount flows to the demister nozzles of the side windows.
Floor level
The main flow of air enters the passenger compartment at floor level, and a smaller amount flows to the demister nozzles of the side windows.
Demist/floor level
The main flow of air enters the passenger compartment in equal parts at the windscreen and at floor level, and a smaller amount flows to the demister nozzles of the side windows.
Demist
The main flow of air enters the passenger compartment at the windscreen and a smaller amount flows to the demister nozzles of the side windows.
Air distribution operating switch
Air distribution operating cables
NOTE: The Bowden cables for LHD and RHD vehicles are identical. However, they are fastened to the air flap operating mechanism with the respective reverse side of their connectors.
The air distribution switch operates with two Bowden cables. The cables operate the air distribution valves in the heater housing.
To remove and install the cables, the rotary switch must be turned as far as it will go to the left. The air flap mechanism engages easily in this position, making the installation of the cables easier.

Removal
CAUTION: Disconnect the battery ground cable. For additional information, refer to Section 414-01 .
Remove the bezel with heater/air conditioning controls (continued).
Installation
NOTE: To install the Bowden cables, turn the rotary switches as far as they will go to the left. The mechanism engages easily in this position.
NOTE: The Bowden cables are identical for RHD and LHD vehicles, although they are fastened to the air flap operating mechanism with the reverse side of their connectors.
Install the components in reverse order.
SOURCE: Heat wont blow through heater or defroster vents
common problem, check under dash by the gas pedal if control arms are muving went selecting from ac to heat cuz this it is the control for the vents to go from ac to heat and to defrost.
SOURCE: my ac only blows from defrost and floor
Look for vacuum leaks. System is designed to fail in defrost mode. so.... vac hose off, for example, would cause an issue like you describe.
SOURCE: AC blows through defrost and floor vents instead of ac vents
You have a vacuum leak in the system that controls the vent doors. First check for cracks at the vacuum reservoir, then check the various vacuum hoses and vacuum motors for a leak.

SOURCE: Heat wont blow through heater or defroster vents
The door in the heater box is most likely stuck. It is located under the dash on the passenger side
NO HEAT ON FLOOR VENTS
