Heater and defrost not working at all in 2009 ford focus

SOURCE: 2000 Ford Focus defroster does not work

try changing the pollen filter.. it could be blocked

SOURCE: how to fix heater on ford focus tried a new motor

check the wiring to the reostat (the resistor that controls the fan speed) also check the reostat has not burnt out. (the reostat should be near the heater motor housing)

please let me know if this helps
cheers

SOURCE: My Ford Focus station wagon. When I have the heat

your damper doors are not closing in the box itself properly and also you need to check the flow rate trhough the heater core its highly possible the heater core is possibly clogged with dirt and debrise' sometimes you can just reverse the ehater hoses and drive the vehicle for a few hours or even days and that bach flushes the dirt out of the core then you will need to drian your radiator and refill with clean antifreeze

SOURCE: A/C and Heater only works on 4

price and replace blower motor resistor

You likely have a defective vacuum motor.
