Electrical strap connecting module to housing selector

Are the heater hose from the engine compartment going to the fire wall hot to the touch ? Is the HVAC - heating , ventilation an A/C system manual or automatic ?
Control System Inputs-Manual A/C
Climate Control Assembly
The climate control assembly has three system controls:

• The A/C heater function selector switch combines a vacuum selector valve with two electrical switches to supply battery voltage (B+) to the A/C clutch circuit and the blower motor speed control circuit.
• Temperature selection is accomplished with a potentiometer connected to the electric blend door. Movement of the control knob from COOL (Blue) to WARM (Red) causes a corresponding movement on the air temperature blend door and determines the temperature that the system will maintain.
• The blower motor switch controls blower motor speed by adding or bypassing resistors in the heater blower motor switch resistor.

Control System Outputs-EATC
A/C Blower Motor Speed Control
The A/C blower motor speed control is located on the A/C evaporator housing, in the engine compartment.

• The function of the A/C blower motor speed control is to convert low power signals from the electronic automatic temperature control module to a high current, variable ground feed for the blower motor.
• Blower motor speed is infinitely variable and is controlled by the electronic automatic temperature control module software.
• A delay function provides a gradual increase or decrease in blower motor speed under all conditions.

A/C Electronic Blend Door Actuator
The A/C electronic blend door actuator is located on the top of the plenum housing.

• Its function is to move the air temperature blend door on command from the control assembly.
• The A/C electronic blend door actuator contains a reversible electric motor and a potentiometer. The potentiometer wiper is connected to the actuator output shaft and moves with the output shaft to indicate the position of the air temperature blend door.
• A 5 volt signal is applied to the ends of the potentiometer. The voltage available at the wiper indicates the position of the potentiometer. The expressed value of the actuator wiper voltage is sent to the electronic automatic temperature control module and is matched with the wiper voltage of the module potentiometer. The control module then drives the actuator motor in the direction necessary to make the actuator wiper voltage agree with the control module wiper voltage.

Did you replace the mode door actuator ? Manual or automatic HVAC system .

When replacing the HVAC control module it will be necessary to allow the HVAC control module to perform a calibration process. When installing the HVAC control module be sure to perform the following:
Important: Do not adjust any controls on the HVAC control module while the HVAC control module is self-calibrating. If interrupted, improper HVAC performance will result.
Place the ignition switch to the OFF position.
Disconnect the scan tool.
Install the HVAC control module.
Connect all previously disconnected components.
Start the vehicle.
Wait 40 seconds for the HVAC control module to self-calibrate.
Verify that no DTCs have set as current DTCs.
When replacing the HVAC actuator it will be necessary to allow the HVAC control module to perform a calibration process. When installing the HVAC actuator be sure to perform one of the following:

Preferred Method (w/ Scan Tool)
Clear all DTCs.
Place the ignition switch in the OFF position.
Install the HVAC actuator.
Connect all previously disconnected components.
Start the vehicle.
With the scan tool, initiate the Motor Re-calibration feature of the Heating and Air Conditioning Special Functions menu.
Verify that no DTCs have set as current DTCs.
Important: Do not adjust any controls on the HVAC control module while the HVAC control module is self-calibrating. If interrupted, improper HVAC performance will result.
Alternate Method (w/o Scan Tool)
Clear all DTCs.
Place the ignition switch to the OFF position.
Install the HVAC actuator.
Connect all previously disconnected components.
Remove the HVAC B fuse for a minimum of 10 seconds.
Install the HVAC B fuse.
Start the vehicle.
Wait 40 seconds for the HVAC control module to self-calibrate.
Verify that no DTCs have set as current DTCs.

Stuck doors or broken connection

According to the book, I'm showing a mode actuator and a blend door actuator next to it. Some models use cables and some use small electric motors to move the doors.
Are you sure you are working on the right door ?

Hi!
If the Temp. Selector Control is set to Heat and blows cold air, your Blend Door Actuator may be stuck or it is inoperative. The actuator is not fixable, if it fails, it must be replaced. Follow the instructions to remove and replace it.

1. Disconnect battery negative cable from battery and properly isolate to prevent accidental reconnection.
2. Remove the instrument panel.
3. Disconnect the electrical connector from the blend door motor/actuator.
4. Remove the four screws holding the blend door actuator to the plenum.
5. Remove the temperature blend door actuator.

the front cover will come off. if you dont see any screws then it WILL unsnap. look for a slot on the top or bottom of the cover. good luck some of them can be nasty

Hi this is tech crazy
the solution to the problem is

You should be able to replace this part yourself. Follow these steps to replace the water actuator:

1. Unplug the refrigerator to completely disconnect electrical power. Turn off the water supply to the refrigerator.
2. Remove the drip tray (Key 23 in the image below) from the bottom of the dispenser.
3. Remove the screws (Key 43) from the bottom of the dispenser module cover (Key 4). NOTE: You model may not have screws at the bottom of the dispenser cover. If not, push down on the top of the dispenser cover and pry out on the bottom of the cover with a flat tip screw driver to remove it.
4. Pull to dispenser module cover up to release the top clips and remove this cover and set it aside.
5. Remove the screws (Key 17) that are on each side of the dispenser module (Key 8).
6. Carefully pull the dispenser module out slightly from the door. It will have wires attached. Pay attention to how the water tube and the ice door assembly are positioned. Pull this module out far enough to remove and replace your water actuator (Key 24).

Reverse the above process for reassembly.

I had the same problem with my water dispenser and since they were willing to sell me a part but provided no directions and I couldn't locate any I decided to make my own for those who might need them. Here is a link to a PDF I made, hope it helps.

Before starting this job I would also like to warn all to please be save and UNPLUG the fridge. The whole job took me less then 30 minutes and I doubt anything will go bad in that amount of time.
