why wont the air work on my 1997 Jeep Wrangler?

My air will only blow on high and no other speed. What is wrong with it? I know its not cool either and I will have to charge the air system.

most likely its the speed selector switch. Replacing it would probably solve your problem. High is the least used position and gets the least abuse so its usually the one that works the longest, you might be able to confirm this by selecting a setting that doesn't work and jiggling the switch and see if it tries to start the fan. if so your switch is definitely your problem.
