Everything else works fine, cool/warm air, top vents, center vents--just not the bottom vents near the feet!

I've removed the glove box to see if I could find anything of interest down there, but all i see is the hot/cold steel cable.

 

up I wanna see if anyone knows anything too, I had this problem with a crx a few years back

 

Servo motor controls the door that diverts air to certain vents. You should see the servo motor on the side of the HVAC box attached to some linkage. Try manually moving the linkage.
