Windshield defrost is not blowing/working
I recently got my ML and really love it. However there are some issues that I have. One is that when I try to defrost the front window, nothing happens. Pushing the defrost button and all of the air is going through the passenger and driver’s blowers only - no air from the window blower nor from the fixed vents on the doors.
Any help would be appreciated!!

Do you have a scanner?
Do you have an owner's manual?

No I do not have scanner.
And I do have the manual but how it will help me with this problem?
I asked about the manual in case I find something you can refer to.
Will air come out of the center vents and the right and left vents if you select that with the dial?
Did you buy the truck with this problem or did it recently happen?
I tried all possible combination but air is not coming from number 1,4 and 9 from the attached picture which I downloaded from the old manual.
I bought it recently so I found that these days.
Also I have noticed that the rear vents does not blow any hot air. Cold air is fine for rear vents, though.

Select the vent setting not working.
Set the Temp up to maximum.
Turn on Auto.
This will force all air thru those selected vents.
In Summer set the Temp down to the lowest setting you have.

So, to make any call on this would require that the codes be read in the AAC Control Mod.
