Please can someone help,

I have a 92 Accord coupe that the blinker relay would continually fire at high speed. I replaced the relay to have the same issue. I checked all the lights, No burn outs. then the actual switch on the steering collum began to smoke. I removed the plastic covers to get to the switch, but cant get it out of the car to replace. I see only two brass screws in the front, but the switch still won't move.:banghead: can anyone help, do I need to pull the whole steering wheel.
