I found a post here about folks that are having trouble with the fan resistor because there fan only works in high position.  I have the opposite problem.  My fan switch works in all positions except 5.  Does this sound like the same fan resistor problem or do I have a problem with my air control module or maybe the switch inside of my air control module?  I have heard that the resistor only controls certain speeds by a mechanic.  Does anybody know what it is I need to replace?  I just have the basic control unit with dials. 
 
See if this helps, but it does look like the resistor is bad.

I replaced the blower motor resistor.  That did the trick.  Problem solved.
 
Curious did it look like a burnt piece of toast.
