Air Conditioning problem, please help!

Can anyone tell me where all the A/C switches are located in a 91 cherokee? i was told it is a bad HVAC switch so if someone could tell me where that is located i would greatly appreciate it. i need to fix my A/C to make it cycle by itself instead of doing it my self from inside the cab. this poses a problem because if it gets left on it drains the battery and im screwed. any info would be much appreciated
thanks
