Dimmer switch causing headlights to not work?
I've got a 92 limited. No high or low headlights. When switched on my left and right and high beam indicators light up and parking lights light up but no headlights
Already replaced the headlight switch with no luck
When I click the high beams it doesnt click. Could the dimmer switch be causing this?

don't take this as assuming your stupid, but i have to ask, have you tried replacing either bulb? alot of times when the indicators come on like that the switch is good and the bulbs are bad. sometimes one light will burn out and it won't be noticed until the other light also burns out leaving you with none. if this is not the case let me know, ill run through some other ideas with ya.

I have a 97 and according to the manuel there are seperate fuses for low and high, left and right. Seems odd that all fuses would blow at the same time though. When and how did this start? Did you go from all lights working one day to none the next?

I was driving and signaled a turn and as I flipped the switch to turn both headlights went off and both turn and high beam indicator came on. I have parking lights but no headlights
I haven't checked the bulbs because I wouldn't think both would burn out at the exact same time

check for power at the headlight connectors using a test light. if you don't have power with the switch turned on then the switch may be bad, pull the switch out of the dash and turn it on and check for power at the conenctor that plugs into the switch. if you don't have power coming out of the switch, then switch is bad. if you have power out of the switch but not at the headlight connector there has got to be a open wire in the circuit.

Dimmer switch could be bad, causing no headlights. Odd that the left/right signal indicators are on, though.
Possible bad ground at the headlights, allowing back-feed from the headlights through the signal lights? Check that you have close to 0 volts to gound on the ground wire at the headlights.
On my '98 ZJ, there's something goofed up inthe steering column, I lose headlights if I tilt up the steering wheel too far. So I don't tilt it up too far

Found this today. Headlight harness by the air box. Jumper for a wire that pulled loose from the connector and tons of dielectric. I thought this jeep was unmolested... still don't know why the indicator lights are on?

Got the column back together and wiggled the wiring harness. Wala head lights. Had a few burnt fuses. Good to go. Going to goto the jy and cut out the harness and solder it in and replace this one
Thanks for the help guys
