Front Climate Control Vents Stopped Blowing

[Lotus Man]

The vents to the front seating area seem to have stopped blowing today, regardless of how I change the controls. I've tried the windshield defogger, full max cold, and varying the temperature, as well as manual control of the fan level. Nothing. The controls on the dash seem to all function fine, as with the center arm rest console that blows air to the rear seating area, but the front seating fans refuse to blow. What gives? Fan fuse? Common problem? Easy fix? Big money?

Thanks in advance,
Will
