Q: turn signals not working

My horn, left turn single, break lights and four way flashers stopped working. It must be something electrical, because when I hold the turn single switch they all work. I was wondering if I put in a new steering column if that would solve all my problems. Or how can I fix my car without it costing too much. I need to get my car inspected, and it won’t pass the test because of the problems it has. I need it fixed as soon as possible. What do you recommend? Thank you.
