2003 Honda Accord Question: AC Vent Fan only operates at high speed setting

My 2003 Honda Odyssey has a variable speed fan. Until last week it was working fine. Now it will only come on when I turn the dial up to full speed. As soon as I back it off from full speed it turns off. It will also come on at full speed when I turn the setting to Auto. Any ideas what went wrong? -
