    Thanks Fixkick the OEM parts help to establish the cable part number, but the end that disappears in behind dash. not really sure where it ends and if reuires lot of removing bits, i think i will leave it alone. My cables that controls the DEF/FACE vent end is broken the end is ok, so to remove the cable i need to access the end which controls the flap in box (somehere).

    ok , and yes, many of the heater parts, require, full dash tank down to replace. all that is in the FSM, get one and then next time know, what lays ahead. i get one for every car i own, used. its just part of there car to me.. all cars (espeically heater box) have unique designs.. that can even very by mid year production changes and even use 2 heater makers, in 1 year.. can cite great examples. but will skip that.... Get the FSM. It even has pictures, and step by step instructions on the HVAC sections. .

Buy one
and install it.
it has clamps remove them or unsnap them and .....
access? its in the dash.
the FSM covers all HVAC work , you can get that and read it
or hope that covers R&R for the cables.
but will cover access. (huge job on some cars)
working on the dash with out and FSM invites more broken parts.
hidden screws and such , and how to get to them are covered in the book.
here is the control panel, pasted

Removal & Installation

  1. Remove the upper console panel.
  2. Remove the instrument cluster finish panel
  3. Release the 2 fitting claws and pull out the heater control assembly.
  4. Using a screwdriver, open the claw of the cable clamp and disconnect the defroster damper control cable. NOTE Be careful not to bend the cable wire. If the cable wire bends, the heater control assembly operationally becomes worse.

This may be a blend door issue. Underneath the glove compartment you should see the part of the AC called the evaporator where the coils are found and the fan. Connected to it is the duct for the air. There should be a door that controls the direction of the air. Observe what happens when you switch the AC vent switch. There should be linkages that connect to the door. The door may be loose or its connections are or the solenoid (motor) might be faulty. Check for loose wires as well. They key is that you get to inspect the pieces since it could be any of the above. If it were a solenoid issue it can be tested by connecting power to it directly. The rest would show physical signs of damages or fault.

Why wont my 2001 ford windstar blow out of vents ? only on defrost?

Air Flow Control
Air flow control is accomplished in the following manner:
  • Primary control is through the function selector knob , mounted on the heater function selector switch, which is part of the heater control .
  • The function selector knob has the following positions: OFF, PANEL, PANEL/FLOOR, FLOOR, FLOOR/DEFROST and DEFROST.
  • The heater function selector switch combines a vacuum selector valve with an internal electrical switch.
  • The vacuum selector valve directs source vacuum to various vacuum control motors (18A318) . Refer to the System Airflow Schematic and Vacuum Control Charts.
  • An internal single-pole electrical switch is also controlled by the selector. The switch controls the electrical supply to the heater blower motor switch (18578) .
  • The position of the function selector knob determines the manner in which the system will operate.
  • Each position of the function selector knob is detented for positive engagement.
  • You probably have a vacuum leak , Pull heater control panel an check for vacuum . A broke vacuum hose or The vacuum selector valve is bad ! Or check for a vacuum hose in the engine compartment being off somewhere !

My air blows out the air vents and the bottom but not at the top under the wind sheild why?

You don't have your selector set to defrost? if you do have it set to defrost, then either the cable that operates your air routing flap has come off, or a vacuum hose has broke or come off the routing flap actuator, or you have a massive vacuum leak somewhere else, leaving very little vacuum to operate your heating system.

Mode door actuator

Hopefully it's the switch behind the dash. I would try replacing your selector switch before messing with the blend door. You have to pull the dash out to access the blend door

Here is the info. I hope the pictures show up. please rate assistance. thx.

Air distribution within the vehicle is determined by the function selector switch position. Two airflow mode doors are used to direct airflow within the heater core and evaporator core housing. The function selector switch/cable assembly is used to position these airflow mode doors. Refer to Section 412-00 for description and operation of each of the system functions.
Function Selector Cable Assembly
The function selector cable assembly moves the airflow mode doors to the desired position using a 2-sided pull-pull type cable assembly. The function selector controls the cable movement. The end of the cable assembly attaches to the airflow mode door/temperature blend door actuating assembly which transfers the cable movement to the 2 airflow mode doors.
An electrical switch is incorporated into the function selector to notify the A/C switch assembly if DEFROST or FLOOR/DEFROST is selected. When DEFROST or FLOOR/DEFROST is selected, the A/C switch assembly will disable the RECIRC request button and send an A/C request to the powertrain control module (PCM) regardless of the A/C request button indicator ON/OFF status.

I have a 2005 Ford Focus. My vent distribution knob turns freely but does not change air direction. It remains blowing from the defrost vents. I pooped off the face around the knobs and stereo to look...

The part you're describing is the blend door actuator. It diverts air through the different ports, (floor, vent, defrost, mix). The good news is depending on what you need (new lever or new blend door) the price runs about $30-40. As far as ease of installation, it sounds like you have unobstructed access so replacing it shouldn't be too difficult.

2002 explorer a/c blowing out of defrost and not dash vents

The direction of the air flow (dash/defrost/floor, etc) is controlled by vacuum going to the switch. There may be a vac line that didn't get connected or was damaged when they put the replacement engine in it. Check the lines on the firewall to make sure nothing is loose.

The Heater selector won't change from defrost to any other settings like floor heat or straight from the dash . the switch on the dash moves but the heat only comes from the defrost vents in the dashboard

hello, sounds like the cable broke or, lots of newer veichels use air lines, any way possible, check and see if air lines are still hooked up to the back of the heater controls, should be 4or 5 air lines together, all hook on one place behind heater controlls

it sounds like the switch lever for the vents, floor and defrost is not switching the vent door that goes to the defroster hose. You need to pull the switch consol out loose from the dash and follow the cable for the defrost that goes to the hose for the defrost. You might also have a broke switch that won't pull the cable enough to open the air for the defrost hose.
