Dash light issues

Looking for some assistance with dash lights. I bought the car (71Dart) a year or so ago and the dash lights didn’t work. It would blow fuses as soon as I changed them. I replaced the headlight switch and corrected it. It lasted a couple of months (driving periodically) and the dash lights are gone again, and instantly blowing fuses. Any thought, if someone suspects a short of some kind is there way to troubleshoot the issue. If the issue took out my headlight switch again, any ideas why?Thanks in advance Ron D
