Park lights not working on 1999 Jeep Wrangler

Park lights, tail lights, and dash lights will not work. I have replaced three headlight switches and still not working. Could it be wiring and which wiring?

check fuses
All fuses are all okay. Checked that out early. This all began when the left park light burned out and appeared to melt the park light connection, however, that light works when the other park lights work.
