I had this same problem. When I bought it from the first owner he told me someone tried to steal the car and hot wire it. When they were in the process of doing so they broke the hazard light switch on the steering wheel. I couldnt figure out why my light didn't work. After a lot of trial and error and research I pulled a used switch from pick n pull and swapped it out. Problem solved. I'm a carpenter and not a mechanic and some how figures it out on my own. Google and YouTube can be very helpful sometimes.
