Alrighty, I have a 01 sport with an ARB headlight harness. I've had it for about 3 years no issues. Pull the knob and the lights and low beams come on. Flip the "multifunction" switch on the column to turn high beams on, and I lose highs and lows and cluster lights.
I've had an issue with that crappy putco harness before, and losing highs or lows brings me back to the relay problems I had with that. But losing the cluster lights in addition confounds me.
I wanted to post this up to get the ball rolling and see if anyone has some ideas or leads. Power and ground lines are solid. For the last year, the multifunction switch occasionally makes a buzzing sound when turnings on turns signals. I'm going to go rotate relays, checks fuses, see if there is anything obvious going on and basically stare under the hood for about 30 minutes. I'm thinking if rotating relays doesn't change anything (lights come on as intended, everything turns off when switching to highs) then it's the multifunction switch knocking something out of whack when I flip to high beams.
Ideas?
