Check the blower motor resitor. Use a 12v test light at the switch and notice the bulb brightness change as you switch settings.. Probably have a bad blower resiter.

It could be worn contacts on the HVAC selector switch. It could also be a bad blower motor but I would check the switch first; contacts lose continuity from a lot of use and wear down. both should be able to be had from a junkyard for rather cheap. I would suggest a loose connection but I don't think that is the case here unless the problem were intermittent.

Check your fuse on the side of the dash, driver side. Look to make sure the fuse has not gone bad, and replace if the fuse to your HAVC has gone bad.
The other thing that can cause this issue is bad vacuum line to your HAVC system. On the drivers side by the corner where the windshield meets in the engine compartment, there is where your vacuum canister. Follow the vacuum lines and look for any damaged lines throughout your jimmy and replace any damage lines.
Poor vacuum will cause the issues your have described and the other thing also that has been found is the vacuum switch to your 4WD on the transfer case to go bad and leak transmission fluid in to your vacuum line causing the same issues you have described.
Start from the beginning and 1.check the fuse, 2, check the vacuum line. 3 check to make sure there is no transmission fluid throughout your vacuum lines and replace the vacuum switch on the transfer case if there is. ($15.00 part at Auto Zone or Napa)
