You could try the self test:

Distribution motor self-test
The motor and flap operation can be checked using the on-board distribution motor self-test function.
The self-test can be initiated by pressing and holding the ECON and RECIRC buttons while turning the ignition switch to the ON
position.
The control module will then compare the current motor position with the values stored in the module and will indicate an error by
flashing the ECON LED (light emitting diode).
If there are no errors, the LED will go out and the system will function normally.
To confirm that there are no errors, turn the ignition switch to the OFF position, then back to the ON position.
Observe the operation of the programmed defrost LED.
If there are errors present, the programmed defrost LED will flash and the system will attempt to calibrate itself.
For additional information on the function of the system, refer to the relevant section of the workshop manual. 2008 MY Java Black TDV8 HSE
