TJ Bright Lights Not Working....

Anybody know what may cause my 1997 TJ's bright beams to quit working? Regular beams are fine. When you turn the brights on, the fog lights and the headlights just turn off. Any idea's? I'm stumped.

High beam switch is toast.

I don't think it's the switch. The "bright light" indicator comes on in the dash when you flip the lever and you can here the relay clicking behind the glove box. Anyone got any idea's?

If you have 'fog'??? lights connected to high beams, the circuit is overloaded so I would guess either the switch has died or the relay had fried out. Most likely the relay is burned if it is the power source.

The older headlight switches would burn the breaker in them when you overloaded the wiring.

'Driving lights' which come on with highbeams need their own source of power. You can use the switch to tag an independent relay for them, but you cannot wire them to the high beams.

'Fog' lights only come on with low beams and already have a relay I believe.

My fog lights are factory and have their own switch under the radio area. I was just saying that the fog lights and headlights both shut off when I turn the bright lights on. Like I said, I'm stumped. Thanks for the advice though. I do appreciate your assistance on this.

The fogs have a tag on the power relay so they will not turn on when the high beams are on so that is perfectly normal and shouldn't have anything to do with your trouble.

And just maybe you also have 2 burned out bulbs? It happens more often then folks think.

The click and bright warning light on implies the switch is working.

I would take a multimeter, even a cheap $2.00 one and see if there is voltage to the headlight plug when the high beams are on. If no power, then I would suspect the relay is dead, if power, the bulb is burned.

The fog lights are wired to turn off when high beams are on (it's the law), so it would appear that at least the dimmer switch is working as the same contact in the switch feeds both the high beam and the fog lamp circuitry . The same circuit drives the high beams, fog lamps and the high beam indicator lamp in the dash.

The high beam output is pin 3 (red/orange wire) of the dimmer switch, that appears to be ok. From there, it runs to connector C107, pin 4 (red/orange wire) in the left kick panel (while driving, your left foot, size twelve or better, should hit that connecter). There should be a large harness connector there with three smaller connectors plugged into it. C107 is the yellow connector, the other connectors are colored black and blue.

Pin 4 from C107 (red/orange wire) runs to the black connector C110, just behind the left front wheel. C110 pin 4 (red/orange wire) runs inside the cable bundle directly to the left head lamp connector, pin

1 and from there to right headlamp connector pin 1.

The fog lights are behaving normally. The factory fogs are wired to go off when you turn on the high beams. You just have high beams that are inop. Two bad bulbs? Rare, but I *have* seen it before. When that happened to me, it was 'cuz the jack handle was shorting out the lights, but that was a YJ, and I have no idea where the jack stores on a TJ.
