A Haiku:

Blower does not blow
Yesterday it blew just fine
What is up with that?

Actually, the blower is blowing but I can only get air to come out of the bottom (heat) vents on the heater setting. The rest of the time I can hear the blower and feel it trying to force air up through the dash but no air is coming through the vents. Used to work fine, anyone know what might have happened here?

Thanks!
