90 Chevy Sub V2500 running light issue

[90burbman]

First love the site. Second if this related issue has been posted I apologize. Just picked up a 1990 Chevrolet V2500 Suburban.

Headlights work lo & high, brake lights & turn signals work to spec. But no running lights with or without headlights on. also my dash lights are inop.

I really havent had a chance to dig into it yet. But besides a possible bad ground im excusing bulbs at this point, do you think its a good possibilty my headlight switch is the culprit? It controls the dash lights & park lights. Anyone else run into this issue? Just trying to do some reserch prior to hours of searching. Trying to get it road ready. Thanks in advance for any suggestions.

Forgot to write fuses, power ground & fuses. Definitely going to start there. i also ordered a headlight switch just in case. But your right Im betting its a fuse. Once I find out for sure I will post the resulted fix.
