I have a 2000 Accord LX with over 103,000 miles to it. Recently, the all air has stopped coming out of the vents in the center of the dashboard. Air is coming out of the side vents and at the bottom of the dash. I think this problem started when I hit the button to defrost and keep some air coming below. When I tried to switch back to the center vents, nothing.

Any help or suggestions as to how to correct this problem would be appreciated.

 

On my 94EX when this happens, I cycle to both upper and lower vents, then to upper vents and this enables air from central vent. Easy enough to try.

good luck
