ignition issuses
 

I was driving yesterday with my air on and radio bumpin I pulled over to answer the phone and shut the 89 cherokee laredo off. Got off the phone started the jeep up and the radio wont come on the fan for the blower wont come on and my turn signals don't work. I got home and checked all the fuses, they all where good. Turned the key back to aux and everything works, but as soon as I turn the key forward. Everything quits working again. I think it is my ignition switch. What do you guys think?
