I had to replace a wiper switch on a 1992 Chevrolet Full size pick-up, and to do so, the steering wheel had to be removed. I think the models are similar. To begin, remove the horn cap, and in some models you may have to remove the attached wire. Go to autozone rent a "steering wheel puller" It has two rods the go in to the ones on the steering wheel and a center bolt that you turn to remove the steering wheel. Before you remove the steering mark where the steering wheel lines up with the steering column with tape. Good luck!
