These are the factory write up procedures, just figured i would group them to a simple write up and pic. They look very easy to access and should take care of any clicking from worn motors.
What you will want to do is make sure what motor is clicking. It can be a blend door motor, mode door motor, recirc door motor. When does it exactly do it?
Does it only happen when rotating the temp from hot to cold?
Does it do it only when changing air flow mods, say from floor, to vent to defrost for example?
Does it do it if you open or close the recirc door only?
Here is a thread with more useful information on this that caused me to issue the how to.

Left side blend door motor
The LH temperature blend door actuator can be accessed from below the LH side of the instrument panel to the right of the accelerator pedal.
1. Disconnect the LH temperature blend door actuator electrical connector.
2. Remove the 2 LH temperature blend door actuator screws.
3. Remove the LH temperature blend door actuator.
4. To install, reverse the removal procedure.
5. NOTE:
The purpose of the module actuator position calibration is to allow the HVAC module to reinitialize and calibrate the actuator stop points. To carry
out calibration, carry out the following steps.
Remove Smart Junction Box (SJB) fuse 15 for at least one minute.
6. NOTE:
When the ignition switch is switched to the ON position, the HVAC module will initialize and calibrate the actuators. Calibration of the actuators will
take approximately 30 seconds.
Reinstall SJB fuse 15. Turn the ignition switch to the ON position and wait 30 seconds before verifying correct LH temperature blend door actuator
operation.
Right side blend door motor
Removal and Installation
1. Remove the blower motor. For additional information, refer to Blower Motor in this section.
2. Remove the 4 glove compartment screws and remove the glove compartment.
3. Remove the 2 RH temperature blend door actuator screws.
4. Reposition the RH temperature blend door actuator and disconnect the RH temperature blend door actuator electrical connector.
5. Remove the RH temperature blend door actuator.
6. To install, reverse the removal procedure.
7. NOTE:
The purpose of the module actuator position calibration is to allow the HVAC module to reinitialize and calibrate the actuator stop points. To carry
out calibration, carry out the following steps.
Remove Smart Junction Box (SJB) fuse 15 for at least one minute.

take approximately 30 seconds.
Reinstall SJB fuse 15. Turn the ignition switch to the ON position and wait 30 seconds before verifying correct RH temperature blend door actuator
operation.
Air inlet door motor AKA recirc
1. Lower the glove compartment.
2. Disconnect the air inlet mode door actuator electrical connector.
3. Remove the 3 air inlet mode door actuator screws.
4. Remove the air inlet mode door actuator.
5. To install, reverse the removal procedure.
6. To verify correct operation, press the RECIRC button and allow 10 seconds for the air inlet mode door to reach the selected position.
Floor vent door motor
1. Lower the glove compartment.
2. Disconnect the floor door mode door actuator electrical connector.
3. Remove the 3 floor door mode door actuator screws.
4. Remove the floor door mode door actuator.
5. To install, reverse the removal procedure.
NOTE:
The purpose of the module actuator position calibration is to allow the HVAC module to reinitialize and calibrate the actuator stop points. To carry out
calibration, carry out the following steps.
6. Remove the Smart Junction Box (SJB) fuse 15 for at least one minute.
7. NOTE:
When the ignition switch is switched to the ON position, the HVAC module will initialize and calibrate the actuators. Calibration of the actuators will
take approximately 30 seconds.
Reinstall SJB fuse 15. Turn the ignition switch to the ON position and wait 30 seconds before verifying correct FLOOR mode operation.
Defrost mode door motor
Removal and Installation
1. Remove the passenger airbag module. For additional information, refer to Section 501-20B.
2. Remove the 3 panel/defrost door mode door actuator screws.
3. Reposition the panel/defrost door mode door actuator and disconnect the panel/defrost door mode door actuator electrical connector.
4. Remove the panel/defrost door mode door actuator.
5. To install, reverse the removal procedure.
6. NOTE:
Because the battery is disconnected as part of the passenger airbag module removal procedure, the HVAC module will initialize and calibrate the
actuators when the ignition is cycled to the ON position. Calibration of the actuators will take approximately 30 seconds.
Cycle the ignition switch to the ON position and wait 30 seconds before verifying correct panel/defrost door mode door actuator operation
