Heater/AC - Blower not working

I came out to start my truck in an Ice Storm 2 weeks ago to find that I have no Blower function at all. I can turn it up or down but no air. The system was making no noises or having any other performance problems. I checked the 40A fuse for the blower and that was fine. Help!

I have a 2005 Chevy Silverado 2500HD Diesel which is off warrantee.

Probably just a bad blower motor. No big deal and pretty easy to fix. Check to see if current is getting to it and test the switch, but if it is recieving current just get a new one and slap it in there. Otherwise, it could be wiring or switches which can be a pita.

Do I have to dissasemble the whole dash and stuff to get at the motor in these trucks?
