Default Air not blowing from AC

The AC fan sounds like it is blowing alright but cold air is not blowing out of vent at the speed that it should. The air seems to slowly "filter" out with little blowing force no matter what the fan speed is on. But the air is cold.
Any suggestions?

Does the fan speed sound change when you try to adjust it slow->fast?

Does the place the air is coming out of change when you try to change it
(defrost, feet, panel)?

The place where the air comes out of does not change unless I change it.
When the AC is on high(fan speed) it will blow cold air fine. After a while (anywhere from 2-20 minutes) cold air continues to come out but at a much lower force while the fan speed sounds and feels like it has not changed.

OK, so it sounds like there's something going on with either the
blend door or the directional doors. Do you have manual or automatic
climate control?

OK, looks like the first step is rebooting the climate control module.

If you go here:http://iihs.net/fsm/?dir=332,
this will take you to the online service manual. Download the PDF,
and on page 2, it walks you through the module reboot.

After that, we're talking about whipping out the VOM and doing
some electrical sleuthing, so hopefully the reboot will do the deed.

And, yes, those service manuals are for a 2005 - if you have the
2008 manual, you'll certainly want to use that instead.

My manual has no info on rebooting a climate control module. A search in this forum shows nothing on the subject.
How do I reboot?

In the online 2005 manual, the reboot procedure is on page 412-00-2
(Group 4 - Electrical, Section 12 - Climate Control, page 2)

I guess I was assuming the 2008 would have the same procedure as
the 2005, but if not, then if you walk through that section in your
service manual, you want to do the general diagnostics, and then if
that looks good, the section under "Incorrect/erratic direction of airflow
from outlets" - or any other section that you think sounds more like
your problem than that one.
