heater fans not working

[sleepem]

For no apparent reason, the heater/AC fan inside the car is gone. The auto- vent- fanspeed- lites all lite up as usual and I can hear soft clicks from near the glove box as the buttons are pushed. The A/C pump starts and stops, and the radiator fans come on and off normally with the Auto setting. All fuses in the entire car are fine. I did a search and only found that someone was able to make the fan come back on with a smack to the glove box area, but no result for me! Any suggestions as to what to consider next? Is there a relay somewhere dead, or internal fan fuse?
The fan was making no signs of distress prior to quitting, the only thing new was an A/C recharge about 2 weeks prior to the fan quitting.

Thanks!
