1993 Heat/Air controls aren't working. The sliding control arm that directs the air to the desired location isn't changing the air flow. It's stuck on midlevel and won't change to defrost or floor etc.

Re: 1993 Ford Explorer heat/air controls
You will need to remove the climate controls from the dash and check to see if the cable has fallen off.........the other end of the cable is behind the glove box,removing it should give you access to check if it has fallen off there. replaacement cables and clips to hold it at the ends are probably only avail at a ford dealer Hope this helps!

In the attached drawing, Part 32 moves Part 26 to direct the air flow to the desired locations. It uses vacuum to operate. The actuator may be bad or the vacuum hose my have come loose when the heater core was changed. With the car running but the blower off stick your head up under the dash on the passenger side and see if you hear a hissing sound. If so it's probably just a vacuum hose come off.

the operating mechanism is playing up and may need changing ,it has a vacumn operated control arm and what i thnk is the problem is the diaphragm has split inside the unit so its not opening to allow the hot air to flow over the radiator inside the heater
Check the motor on the top of the heater plenum. It turns a shaft to shift the blender door
which controls the input to this plenum either the heater core or the evaporator core (ac). You may find the motor is OK but the shaft (plastic) has broken and the blender door has to be replaced. This is a costly job that involves removing this plenum after removing the dash. A shortcut I found online was to cut a hole under the blender door and replace it through this opening. After replacing you can seal up the hole with epoxy. I cut three sides of a square hole leaving the back uncut. Pull down and the blender door can be removed. My problem was on a 1997 Explorer.
is the heater tap opening??? have to check by sliding hot to cold control and getting someone to look under bonnet while you do it ...should be easy to see if the cable is moving it,if electrical check fuses or owners manual for fuse location,eg climate control
