AC VENT/BLOWER PROBLEM
Hi All,
I have a 2005 D3 and having problems with the air conditioning.
At first the front vents were working fine but no air was coming out of the back upper vents.
After several weeks, when I put the AC on, i can feel it cooling inside the dashboard but no air coming out of the vents. I can feel the cool air on my legs and laps which means the AC is working. The thing is you can actually hear the sound of the AC blowing at various speeds when I modify the control which I believe that the blower is working.
What might be the problem?
Can anyone help?
Thanks
NL

After that you can try this..
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.

Thanks Everyone for the advice.
I had scheduled to run through the various options suggested this weekend but something happened which I can't explain.
For no obvious reason, yesterday when I was going home from work, when I turned on the AC, it worked perfectly with no problems whatsoever. Air was blowing out of the vents normally. Even air was coming out of the upper back vents unlike before.
Can anyone explain this?
Don't get me wrong, I'm happy the ACs working properly for now.
I'm hoping the fault doesn't reoccur.
Thanks,
