I just purchased my first Jeep. It's a 1989 Wrangler with a 2.5L and 5 speed. I started her up, and tested the turn signals. They work. When I tried to turn on the wipers, they didn't move. About two seconds later, I noticed a small puff of smoke wafting out of the square hole on the side of the steering column where the lever goes through. I immediately turned the wiper function off, and the smoke stopped. I'm not good at tracking down electrical issues, especially on a vehicle that is new to me. Is there a switch or other electrical component inside the column that could have gone bad and produced that small bit of smoke?
