94 Supercab, last night the led gauge lights started flickering, and my lights weren't working. they would work intermittently, and with the flash to pass being held, but would not stay on for the life of them. forward to tonight, i'm leaving work at 10pm and my low beams miraculously work, but i lost all dash illumination, gauges and climate. i just need to know what it is, the cabin fuse for the dash lights is good, and i replaced it twice to no avail. i took the trim off the dash and ensured the connection on the back of my cluster was good too, which it is. i hit a big *** bump and the lights all flickered, too. anyways, is it my multifunction switch, headlight switch, or something in the middle? never seen this happen before. thanks

 

Most likely the Main Light switch is the issue
Flash to pass 12volts goes directly to Multi-function switch by-passing Main Light Switch

1994 still used Main Light switch as Dimmer control for dash lights, no connection to multi-function switch

Headlights 12volts run thru main light switch, of course, then to multi-function switch, but as said flash to pass doesn't

So pretty much all the symptoms have Main Light switch in common more than fuses or multi-function switch

 

I'm having same issue and I already replaced my switch
but its still having the issue and if you push it in just enough you can have both but every time I hit a bump it goes out

 

If moving the main light switch a bit causes lights to work and then then go off then new switch is faulty
