So the fan isnt blowing? or it is? the heat just isn't warm? or no air is coming out of the vents regardless of the fan switch position?

the fan doesnt turn on

Maybe a bad fan switch.. maybe remove the wire connection from the fan motor and test if its getting voltage with the ignition on and with the switch on. It should get twelve volts, if nothing then the switch is the problem. I hope this does the trick.

Look for another switch assembly if yours is bad. Junk yard will be easy or someone here selling a good known part.

Heh. Sorry, I forgot I posted here. I would agree that the switch is probably messed up somehow. Before you go buy a new one, take the switch assembly apart and make sure its clean and that all the contact spots are touching the switch. Also, make sure the wires running to the switch are connected and that the insulation is not cut anywhere. A used switch from a junkyard shouldn't be too expensive. Good luck Keep us posted.
