Default '88 exterior lighting issues

Faulty lights at the moment: both brake lights, turn signals (front&rear) right high beam.

They were all working, then stopped working, got a fix it ticket. Got fix it ticket extended another 10 days, took it over to my buddys garage to check it out. When i got to the shop, all the issues went away, had everything working. Even replaced the rear brake light bulbs. Got home at 1:30am last night, stopped by the police station to have them sign my ticket. Went out to get cigarettes about an hour ago, and no everything is back to not working again.
So the brake lights, turn signals, and the right high beam, all goes out at the same time? WTF?

Any ideas.
I found these two threads.
--> https://www.cherokeeforum.com/f2/hel...working-18911/ (talks about a "multifunction switch" being the issue possibly.)
--> https://www.cherokeeforum.com/f2/no-...-67660/index3/ (turn signal switch, it suggests??)

Appreciate the help.
It's cold as a mother outside, so i kinda want to have a good idea of where im starting if im going out to try and fix this ****.

I would replace your headlight switch, replace all of your associated fuses and check your grounds. Especially your main negative cable. Good Luck!!

Yeah, were fairly positive its not the fuses, i was at lkq a month or two ago, and just walked around to random cars and prolly pulled about 100 fuses. so we have already replaced every fuse, and tested the connections.
It's gotta be the freaking brake light switch or turn signal switch causin the issues..

I finished taking the brake light switch and took apart the column and steering wheel to get to the turn signal switch, i'll replace them with new tomorrow and see what happens.
