Temperature blender actuator fuse

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.

There isn't a fuse for the blend door actuator. It is powered by the A/C control panel. If other door actuators work, replace the actuator.

No, the blend door actuators are either vacuum controlled devices or are tiny motor controlled actuators. There is no separate fuse. If the heater control panel operates normally otherwise, then the fuses for heater controls are good. Look on the heater case under the dash-see any vacuum hoses?

There is more than one fuse for the radio. I know that one controls the power and there is also one for the memory and sometimes they have a third fuse as well. Take a look in your owners manual for the location of the fuses. \hope this helps

Behind the glove box you will see a box with a plug going to it mounted in view. This electronic module controls the blender door if that is what you mean.This is called Air Temperature Actuator easily seen.Dont forget to rate my solution and leave testimonial it is how i earn my achievements Thanks in advance

Suspect it is the blend door actuator, but please see my tip at http://www.fixya.com/cars/r6235876-no_heat_fan_blowing_cold_air . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info. Below are instructions for replacing the blend door actuator, but don't replace it unless you're sure it's bad. Autozone has it for $36. First, take it out, plug the connector back in and see if it turns when you change the temperature control. If not, the problem can be in the controller or the actuator. If it is clicking, the problem is stripped gears. If it isn't doing anything, you can check for voltage at the connector with a voltmeter. Connect the black meter lead to a good ground point and probe the connector terminals with the red lead while changing the temperature setting.

Blend door actuator removal and installation:

Remove the fuse labeled HVAC CTRL (BATT).

2. Install the air temperature actuator and tighten the mounting screws to 13 inch. lbs. (1.5 Nm).
3. Install the knee bolster
4. Install the left closeout panel.
5. Install the fuse labeled HVAC CTRL (BATT).

Sounds like a blend door actuator.

Right Air temperature Actuator Right Air Temperature Actuator

To Remove:

1. Remove the right sound insulator.
2. Remove the instrument panel compartment.
3. Remove the body control module and the HVAC programmer from the brackets and lay aside.
4. Disconnect the electrical connector from the right air temperature actuator.
5. Remove the right air temperature actuator.

To Install:

1. Install the right air temperature actuator
   • Torque the fasteners to 12 in-lbs (1.4 Nm).
2. Connect the electrical connector to the right air temperature actuator.
3. Install the body control module and the HVAC programmer into the appropriate brackets.
4. Install the instrument panel compartment.
5. Install the right sound insulator.
6. Recalibrate the actuators.

Left Side Air Temperature Actuator (2003-2006) Left Air Temperature Actuator Replacement

To Remove:
CAUTION
Do not apply power to the actuator when it is removed from the HVAC module.

1. Remove the I/P insulator panel.
2. Disconnect the connector from the left air temperature actuator.
3. Remove the actuator mounting screws.
4. Remove the left air temperature actuator.

To Install:

1. Position the left air temperature actuator on the HVAC assembly.
2. Install the actuator mounting screws.
3. Connect the electrical connector to the actuator.

5. Calibrate the actuator.

---
Calibration To Calibrate:

1. Turn the ignition switch to the OFF position.
2. Remove the fuse from the HVAC control module positive circuit. NOTE: The fuse must be removed for more than 60 seconds to clear the control module memory.
   
3. Wait at least 60 seconds.
4. Install the fuse.

the only thing that can change the air from hot to cold, or vice versa is the blender door. under your dash is a box which has 2 compartments. one with your heater core which is hot and one with ac which is cold. the blender door basically diverts which on the air in your car is being drawn from. if it is cold, air is moving on the ac side. if its hot, air is moving through the heater core side. if its warm, the door is in the middle. your temperature control knob is conecteted to an actuator, which moves that door. the actuator is a motor, but if it goes out, the door will be stuck on whichever side it is on. i would check that first. hope this helps
