S-10 front panel screws, name of tool needed for removal to access front panel in interior?

Replacing the air blend door actuator (commonly known as the air blender) on a 2005 Lincoln Aviator is a moderately challenging task that requires some mechanical know-how and the right tools. The air blend door actuator is responsible for controlling the temperature of the air that comes out of the HVAC system by adjusting the position of the blend door. If you're confident in your abilities, follow these general steps to replace the actuator:
Note: Before starting any work, ensure the vehicle is turned off and the battery is disconnected to avoid electrical hazards.
Tools and Materials Needed:

• Screwdrivers (Phillips and flat-head)
• Socket and ratchet set
• Trim panel removal tool (optional)
• New air blend door actuator
• Shop manual or repair guide for your specific vehicle (for reference)

Step-by-Step Guide:

1. Locate the Actuator: The air blend door actuator is usually located behind the dashboard, in the HVAC housing. Access to it may require removing some interior panels and components, so consult your vehicle's repair guide for specific instructions on gaining access to the actuator.
2. Disconnect the Battery: As a safety precaution, disconnect the negative terminal of the battery to avoid electrical mishaps while working on the vehicle.
3. Remove Interior Panels: Depending on the location of the actuator, you may need to remove portions of the dashboard or other interior panels to access it. Use a trim panel removal tool or a flat-head screwdriver wrapped in cloth to avoid damaging the panels.
4. Disconnect Wiring Harness: Once you have access to the actuator, locate the wiring harness connected to it. Gently disconnect the wiring harness by pressing the release tab and pulling it away from the actuator.
5. Remove Actuator Mounting Screws: The actuator is usually secured to the HVAC housing with screws. Use a socket and ratchet or a screwdriver to remove these screws and detach the actuator from the housing.
6. Install the New Actuator: Position the new air blend door actuator in place and secure it with the mounting screws. Make sure it is properly aligned with the blend door and HVAC housing.
7. Reconnect Wiring Harness: Attach the wiring harness back to the new actuator, ensuring a secure connection.
8. Test the Actuator: Reconnect the negative battery terminal and turn on the vehicle. Test the new actuator by adjusting the temperature controls and checking if the blend door moves accordingly.
9. Reassemble Interior Panels: Once the actuator is functioning correctly, reassemble any interior panels or components you removed earlier.
10. Test the HVAC System: After reassembly, test the entire HVAC system to ensure everything is working correctly. Check for any unusual noises or issues with temperature control.

Always follow safety precautions and consult your vehicle's repair manual for specific instructions and diagrams related to your Lincoln Aviator's model year. If you are unsure or uncomfortable performing this task, it is best to seek assistance from a professional mechanic.

. Air won't blow out of the floor or center vents just defrost ? Do you have manual or automatic climate control ?
Air Flow Control
Air flow control is accomplished in the following manner:

• Primary control is through the function selector knob mounted on the A/C-heater function selector switch, which is part of the integrated control panel.
• The function selector knob has the following positions: OFF, MAX A/C, A/C, PANEL, PANEL/FLOOR, FLOOR, FLOOR/DEFROST and DEFROST. The A/C-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 Vacuum Control Diagram , System Airflow Schematics and Vacuum Control Chart .
• Two internal, single-pole electrical switches are also controlled by the A/C-heater function selector switch. The combination of these electrical switches controls the electrical supply to the A/C clutch and 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.
• Vacuum Control Motors The vacuum control motors (18A318):
  
  • are located on the A/C evaporator housing, A/C recirculation air duct and heater air plenum chamber (18471).
  • direct system airflow to the vehicle interior as determined by the remote climate control module or manual override.
  • The five-passenger seating configuration has an additional vacuum control motor mounted on the heater air plenum chamber to control airflow to the rear seat A/C register (19893).

the mode selector is actuated by Bowden cables. When you turn the selector switch, the cable winds on a spool and that rotates the mode door. the cable may have come off either end. You need a U shaped set of radio puller tools that go in the 4 holes in the front of the radio. Then you slide the Us to the outside to compress the clips and allow to pull the radio out. Then there are 4 screws to remove to remove the finish bezel. Then 3 screws hold on the climate control head.

With the radio out, you can rotate the selector knob and see what it is doing. If you remove a cable, rotate it counterclockwise fully before disconnecting it.

You can buy a whole head for $10 used at car-part.com. look on page with * for lowest cost part. You can use 2000-07 contol head.

The clicking noise is the door blend actuator. It is located in the dash panel behind the radio. It is about the size of a pack of cigarettes.

I priced this job at a dealer and it came in for around $300!

This is a really simple repair, a great choice for the do-it-yourselfer.
Here are the steps/procedures for doing this repair yourself in about 30 minutes:

• Tools to do the job:
  
  • Ford radio removal tools
    
  • 5/16 nut-driver
    
  • Flashlight
    
  • Small hands or band-aids
    
    

• Remove the radio -
  
  
  • Insert the U-shaped 'handles' into the vertical pair of holes on each side of the front of the radio until you feel it hit an indent / click .
    
    
  • With both tools inserted, push outward on the top of the tools while pulling the radio out & away from the dash.
    
    
  • Disconnect the 2 wire harness connectors & the antenna.

• (Optional) Remove A/C & Radio control dash panel

• Removing the A/C & Radio control dash panel gives you additional access to the actuator to help with removal and installation. This is not a difficult option.

• Loosen and remove two screws revealed just above radio when radio was removed.
  

• Loosen and remove two screws inside (one on each side) the drink holder & ash tray drawer.

• Gently pull the loosened section of the dash panel forward.

• Do not remove connectors for A/C control panel. You'll need the A/C control panel active to align the driver post of the actuator with the blend door drive hole.

• You might want a helper to hold the panel off to the right while you work.
  

• Reassembly is exactly reverse.

• Remove / replace the blend door actuator -
  
  
  • Looking in through the radio opening, locate the actuator module - a white plastic unit about the size of a pack of cigarettes.
    
    
  • Use the nut-driver to remove the three 5/16ths mounting screws.
    
    
  • Disconnect the wiring harness located on the side
    
    
  • Reverse steps to re-install
    
  • In order to line up the shaft I had to crank the car and move the temp selector. Note: You do not have to turn on the A/C system for the temp selector to control the actuator, but you must have the actuator control cable re-connected.

• Reassemble the dash panel.

• Reinstall the radio (watch that no cables bind during the reinstallation.

• What the actuator is / does:

• Inside this unit is a circuit board, motor and small plastic round gears. The gears then rotate the actuator, which in turn opens and closes the damper allowing the air to pass through the heater core.

• What happens is some of the little teeth break off creating a gap on the gear wheel. This gap prevents the gears from driving the actuator shaft.
  

• The unit may be known as a heater damper module by the dealer. Should cost around $60-$75. (One reader acquired the actuator for $34 from O'Reilly.)
  

• This unit was purchased from Advanced Auto for $ 45 and the flat rate is .4 hours. I did mine in around thirty minutes with the hardest part being getting the radio out ( it seemed stuck ).
  

Here is an exploded view of the heating/air conditioning blower box. This contraption is located on the passengerside under the dash. I've changed heater cores on other cars but never worked on a caravan so not sure how difficult it'll be. You may need to remove a few cover panels to access this and the heater core #22 is located behind the distribution box #6 containing parts 7-18 and hopefully comes off as a unit. I wouldn't want to put it back together just looking at the pic. You may just need to remove the heater tube cover #4 to access the connections and slide out the core.....NAH couldn't be that simple!!! Hope this was of some help. Good luck.
