TJ brights not working?

I have a 97 Sahara and the brights haven't worked since I bought it and they didn't work for the previous owner either. Turn signals, headlights, reverse lights and driving lights all work, but no brights. It's not so bad except for when I forget and I go to turn the brights on and everything else turns off and then the road disappears haha

Apart from the obvious with the bulbs being spent, what else should I check?

It's more likely the multifunction switch is at fault.Fuse #12 is the circuit that runs the headlamps.

In the '97 service manual, Fuse #10 (30A) in the underhood fuse box (Power Distribution Center) powers the headlamps but if your low beams work then that is not your problem. The RED/ORANGE wire out of the multi-function switch (turn signal switch assembly) feeds the headlamp high beams. The multi-function switch in many cases is the cause of the problem. Check all the "cheap" stuff (fuse, wires, bulb, connectors, connections, etc.) first before buying a new switch.

Replace the switch, they do go bad. My '97 TJ is on its second turn-signal switch that also controls the high-beams.

Interested to see the results. i have followed the schematic back to the multifunction switch as well. though just need a reassurance this is the issue.

Found out it was a rotted wire on the back of the driver's side headlight. I'm amazed the lights were working at all! Dug out the rotted wire and reconnected the freshly stripped wire and they worked!
