Possible Cause for Fan Speed Control Switch DEAD

I was driving home from the storm in Northeast and the switch that controls the fan speed went dead. I had the AC on to help with the fog on the windows before it just died. Any ideas on what would cause this. Think something must of burn't out. Thanks for any help you can offer.

Most likely the fan speed controller.
Lots of threads about that.

Thank you, I didn't know what to technically call it.

Update: 2/5/15 Turned out it was the blower motor. At least one car fixed. Thanks again for everyone's input. I greatly appreciate the help you have extended to me over the years.
