Brake lights/headlights/running lights

HELP! Alright so this is my 93 I picked up a month
ago or so.. when I got it, the tail lights wouldn’t
work unless I hit a bump and the headlights would
flicker and I would have to switch from dims to
brights a couple times to get the brights to work. I
re-did the ground on the frame and everything was
fine. The tail lights and turn signals worked fine,
and the headlight issue didn’t seem to be doing it
as much. But I noticed when I turn my running
lights/gauge lights on, the right turn signal light
stays on (doesn’t blink) and the left one blinks fast
and when I first noticed this issue the gauge lights
would flash with the left turn signal. Turn the
running lights/gauge lights off and everything is
back to normal. I’m going to change the multi
function control switch but any other ideas?
Maybe wiring issue? Not sure just need some
opinions! I changed the headlights switch and now
the right signal stays on, left one blinks fast (even if
running lights are off) and only one headlight
works. Headlights and tail lights are new!
