The symptoms you describe, such as the flashing amber light on the defrost knob, loss of airflow, and clicking sounds when opening the driver's door, suggest a potential issue with the blend door or the blend door actuator in your HVAC (Heating, Ventilation, and Air Conditioning) system. The blend door is responsible for directing the airflow between the various vents, including the defrost vents, dash vents, and floor vents.
Here are some steps you can take to further diagnose and address the issue:
1. **Blend Door Actuator Inspection:**
The clicking sound you hear when opening the driver's door might be related to the blend door actuator. The actuator is a motorized component that controls the position of the blend door. Check if the clicking sound is coming from the actuator. If you can access it, inspect for any visible damage or obstructions.
2. **Check for Obstructions:**
Sometimes, foreign objects or debris can obstruct the movement of the blend door. Check for any visible obstructions in the HVAC ducts.
3. **Perform HVAC Self-Test (if available):**
Some vehicles allow you to perform a self-test on the HVAC system. Refer to your vehicle's service manual for instructions on how to initiate a self-test. This may provide additional diagnostic information.
4. **Inspect Wiring and Connectors:**
Check the wiring and connectors associated with the blend door actuator and the HVAC control module. Ensure there are no loose connections, damaged wires, or corroded connectors.
5. **Professional Diagnosis:**
If the issue persists after the above checks, it may be advisable to seek professional diagnosis from a qualified mechanic or a Jeep dealership. They can use diagnostic tools to retrieve fault codes and perform more advanced testing on the HVAC system.
6. **Consider Blend Door Calibration:**
In some cases, the blend door may need recalibration after a control module replacement. Refer to your vehicle's service manual for instructions on how to calibrate the blend door system. Calibration procedures can vary between vehicle models.
It's worth noting that even though you replaced the control module, the issue may still be related to the blend door actuator or the blend door itself. The clicking sound when opening the door suggests that there may be a connection.
Remember to consult your vehicle's service manual for model-specific information and procedures. If you're not comfortable with the diagnostic process, seeking assistance from a professional mechanic is recommended.

Try disconnecting the hoses going to the heater core at the firewall, then use a garden hose to flush out the system. Do one side first, then the other..reconnect hoses when completed..

stuck blend door or bad blend door actuator

Blend door may be sticking thus mixing too much cold air with the hot. Bad blend door actuator, vacuum leak or blend door seal is bad.

Usually a sign of a stuck blend door under the dash.
Could be a faulty blend door actuator, or the main controller.
You may need a shop manual to make the repairs since this is generally beyond the abilities of a DIY repair book.

The blend door actuator will not be the problem, the blend door will be stuck or broken, common problem.

My blend air door is stuck on my 2010 liberty. I have removed the actuator panel on the drivers side and the middle door that controls the air flow to the dash is completely seized. There are 4 blend air doors on this liberty, 2 control the heat/ac and 2 control the air flow.
there is no access to them from the drivers side and the passanger side looks like I have to cut into the air box to get to them.

Jeeps are notorious for having broken temperature control (Blend Air) doors. A malfunctioning Blend Air Door actuator probably caused it to break. The dash will have to be removed to replacethe door and the door actuator.
