I'm not sure what year that is (sorry not into all the whipper snapper honda stuff lol) but I know later model civics have cabin filters. See if there is a cabin filter available for your make and model, if so there's a good chance it's clogged up. That would contribute to poor air flow.

If you don't have a cabin filter, you can always pull your blower motor out and inspect for anything that's there that's not supposed to be there. Sometimes, if a car sits long enough, all kinds of small critters can get in there and store food or build a home haha. I've heard stories of everything from stored up dog food, to not so lucky chipmunk clogging a blower motor lol.

If there's no cabin filter, no critters, then your most likely loosing power somewhere. In this case, you'll need a schematic (wiring diagram) and a DVOM (digital meter) to hunt down where your loosing power.

Basic voltage drop check procedure goes as follows:
-Identify voltage drop suspects on schematic- blower motor, relay, controls, connections, etc.
-Turn car on, turn A/C on to were blower motor isn't blowing correctly
-Take DVOM in "direct" volt mode and check suspects with test leads (also make sure leads are in position for volt mode on tool, if you have one that offers more)
-Readings should read very close to 0V; any significant reading (over .5V) is considered a drop and is robbing your blower motor of power.
