that just happened to me. Just take the steering wheel off. No need to take all the electronics off (at least in my yj) put the relay switch up or down and you can press the little piece out with a small screw driver. It takes a little coaxing, but itll get there. I cant remember you you have to take out the white clip thing thats after the steering wheel. The thing that makes it stay in the turn signal until you click past it. Either way, once you get that out, just get a new lever and press it in. Mine snaps in and out with force but will not fall out on its own.
Hope that helps.
