Weird dash problems last night

[70c10]

Recently I posted pics of my new white dash. Well, last night I fired the truck up for the first time with the new cluster to check the new tach. It worked great but when I tested my blinkers (with the headlights turned on) the left side of the dash would blink alternately and when I tried my hazards the freakin hi-beam indicator would blink. If I turned on the hi-beams and tried the blinkers they would blink opposite . I was thinking my headlight switch went up even though I replaced it 4 years ago. I switched printed circuit panels from one of my other dashes and it all works perfectly now . Today I saw a post from byrd about the 2 little screws at the top of the circuit panel that are grounds and should be checked. I think one of them was in crooked!. The funny thing is that panel looks brand new with no breaks so I bet that was it all along. I just wanted to share this since there have been alot of posts lately about dash problems.
