panel mode defrost mode ls 2006 testing

[Surfdude 49]

Greetings
My Lincoln ls switches when changing mode positions but air does not come through the selected areas. I believe from what I have researched that a door may be binding. Am I on the right track and can anything be done short of pulling the console?

You might start with the self test...

The DATC module self-test through the front panel display:

• can be initiated at any time. Normal operation of the system stops when the self-test is activated.
• is entered by pressing the OFF and DEFROST buttons simultaneously and then pressing the AUTO button within 2 seconds. Record all DTCs displayed.
• concludes by reporting all on-demand DTCs. Follow the diagnostics procedure given under ACTION in the DTC index for each DTC given.
• reports individual on-demand DTCs as 4-digit DTCs (less the alpha character).
• will calibrate all the mode doors and check all analog inputs. The DATC module will only report on-demand (hard) faults that occurred while the DATC module was conducting its self-test.
• will light all control panel display segments if no faults are detected.
• will report individual on-demand DTCs without the °C symbol lit.

To exit the self-test, press the DEFROST button. This will clear all on-demand codes from the DATC module memory. If no button is pushed, DTCs will continue to be displayed.

Upon exit from the self-test the DATC module returns to operational status. The DATC module executes a hard (cold boot) reset which places the DATC system in the OFF mode.
