I own a 2003 F-150, the climate control will not switch to panel/floor, or
floor. It only works on vent, defrost, and floor/defrost, but does not
blow on the floor. I followed the vaccum lines down to the actuators, and
there is vaccum at the end of the lines. I dont know how much vaccum I
need or if the actuator is broke. Any help would be appreciated.
