Lights not working.

[Mh91344]

I have a 1986 K20 custom, my headlights parking lights and interior lights are not working. I have replaced the headlight switch and the alternator, because I thought it was going bad but tested out good. My blinkers and hazards work, I know they are on a different circuit. I’m kind of at a lose of where to go from here now. Any help would be great, thanks.

Just noticed when I turn on my left blinker, both tail lights flash along with some dash lights and the right front side market light. When I turn on my right blinker the only the right side lights blink as they should.
