Air and Heat won't blow! Fans turn on!

I a have seen endless amount of post on this. I am going to set my Jeep on fire if I can't figure this thing out. I have a 1993 Jeep Cherokee 4.0 4x4, green POS. When I turn the a level controls up and down nothing happens. No air no heat, but I can hear the fan engaging. I changed the resistor a few months ago because the controls only worked on level 2 and high. After changing it they still only worked on 2 and high. I have looked for vacuum leaks and all the fuses are good.

The Jeep is the bottom of the line model everything manual, no cruise, no ABS. Please help I have tried eveything! Thank you guys very much in advance!

If the fan is running but no air is coming out of the vents it would likely be a stuck diverter.
