1994 Mitsubishi Expo mileage: 144,000. My turn signal indicator switch located on the steering column went out. I am tempted to fix it myself due to the large expense to have it replaced. Do I need to pull the steering column? This model has a driver side airbag and that's the part that scares me. I do have an expansive knowledge of car repair, but much better on older models. Is there a website, or manual that will help me in my dilemma?
