AC only works when key is in Accessory mode

[workingfast]

I have a 1994 Jeep Cherokee. The A/C has always worked great. A fuse blew for the blower and I replaced it. Worked that day then I go to start and it wouldn't work. I checked the new fuse and it was fine. Checked fuses under hood. Every Time I checked I started the Jeep. Then I went to test and decided just to turn the ignition to Accessories. The A/C worked (Might be just Blower). Turned the Jeep on and no air comes out. Moved back to accessorie and cold air blows.

The only thing I can think of is that contacts in the ignition switch don't connect in On but do an accessories. I'd hate to find out after replacing the ignition that it was something else. Any help for these hot Texas summers would be greatly appreciated.
