Vent/defrost/air flow control knob

[rockwalltitan]

My knob that contols the airflow into the truck, has settings in between each label. Why is this? If I am in between two, which one am I on? Is it just my truck or is this the way it was designed?

You know i have wondered the same thing before if you get it figured out let us all know.

Same here, I can't tell a difference when the knob is in between.

That's funny cause I have wondered about the same thing...seems in both of ours the air continued to blow at the last setting...LOL

Also, a note between the other knob....

On the '04 it was numbers 1-5....the '05 it is a 'gradient' type of indicator going from lil to big....

Thats weird, I was going to ask this same question, its been buggin me. I'm guessing its a combo of both settings your between if you know what I mean. (Thats how my 3500HD Chevy is anyway)

Yep, that's the way I see it also, i.e. if it's between defrost and floor you will be splitting it between the two etc,etc, etc.

I think it's sort of a fine tuning set up allowing more air to be blown to either the bottom, defrost, panel instead of an equal amount to both outlets.

I got an idea, how bout somebody get in their truck and test this theory...

Not me, I'm too lazy, and it's 3 degrees outside... but I have wondered the same thing...
