what can this be?

I have a 2007 nissan altima,when I first get in the car after sitting throughout the night the high and low control knob will not blow any air at all,after driving the car for about 20-30min it will work just fine and I can adjust it to my likeing. Seems like it stops working after the cars been sitting for a period of time. Anyone have any advice? Thank you
