'97 wrangler ignition switch?

I have a '97 wrangler that I believe is having some ignition switch problems. This afternoon, after starting, the radio, fan motor, turn signals, would not operate, and the brake light stayed on. The jeep otherwise ran/drove fine. After restarting a little later, it had the same problems as described above, but after a couple minutes, everything returned to normal. Fan worked, turn signals worked, radio played, brake light (on instrument cluster)went out. My son thinks he may have moved the key a little when everything started working again, so I'm leaning toward the ignition switch being the problem. The key on-key off method revealed error code 42 (open condition detected in the asd relay output circuit), but no codes revealed by a drb2 scan tool. Am I right to think this may be the ignition switch, or should I consider some relay? The jeep hadn't been started prior for several days, and we had the lowest temp of the season the other night (20 degrees.), and I suspect that the temp may have had something to do with the switch, after starting, maybe not returning completely to the normal 'run' position. Thanks for any help!
