Could a bad ignition switch cause my AC not to blow cold on a 1998 mercury villager ?

Question

I was at a stop light and suddenly my ac didn't blow cold air anymore. I had the refrigerant checked and its not that. I was told my master switch could have a short in it. Then I mentioned that my radio and sometimes my windshield wipers dont turn on all the time. I have to sometimes turn the car off and on and then the wipers and radio come back.The mechanic wiggled my iginition switch while the car was running and said it was really loose. He said if I got a new one it would probably fix the AC issue. Oh I forgot to mention he sent a electric shock or something to the compressor and kicked on while he was checking it and it was blowing cold. So I thought ok just wiggle the ignition switch right but no ( AC hasnt work since the shock) sometimes it kicks on though while driving and then off - cycling through some sort of on off thing. So does the ignition switch really have anything to do with it or not ?
