Another Headlight Issue 92' YJ

So....


Problem:
- Headlights work for about 15-20 minutes then randomly turn on and off.
- Turn on and off faster (about 3 minutes) if I have high beams and low beams on together.

What I've done:
- Checked the fuse/relay in the engine compartment. looks fine 30amp
- Checked under dashboard fuses (all of them) just to make sure. Still all fine.
- Checked wiring at headlamp, connector module, and switch under the dashboard. Cleaned and looks great.
- Also wiggled aggressively while lights are freaking out and got some slight response but still same result.
- Checked both side ground wires. Cleaned both and reconnected.
- Self educated myself with google-ing and youtubing everything. Ended with no help.

Questions:
- Think it could be a corroded wire that I can't get to?
- Should I just try a conversion kit and if so which one?
- Mechanics and Electric mechanics have no idea whats wrong and wont take the time to sit and watch the headlights go out.... lazy asses.
- what should I do????????

I've ran into these same symptoms 5 times (on different vehicles). Twice I fixed it by replacing a headlight, twice by replacing the light switch, the 5th vehicle we're still trying to figure out.

I'm having similar problems.. but my lights just start blinking randomly. Both brights work and on dim works.. I bought both new headlights and then the opposite dim didn't work lol. I switched the lights and the same light was out.. So i know it isn't the lights. Then the other day my Dash lights went out. All fuses are good. So i guess im going to be replacing the switch inside. Let me know if you find out anything. I'll let you know aswell.

JeepLover1987, this sounds like the switch has gone bad, can't be sure. But, I think I have a spare headlight switch. I'll check in the morning (later today at this point) to be sure. If I do have it, it's yours. I'll touch base with you later today to verify that I have it.

Thx for everyone's help and posts.

I took apart the switch and there doesn't seem to be anything wrong with it. Connections are good, I cleaned and re-greased the inside, copper seems to be very shiny, and I still have to buy a new switch?

and Thx Dutch 95 but thats not neccessary I'll just buy a new one for cheap.

Also, the headlights are new and I don't have any issues with any other lights except for the headlights.

and how sure are you that it is the switch even if it "looks" new and has been cleaned?

Thumbs up

Just to end the thread I want to say that you were right in buying a new switch.

Bought a new one from Oreilly auto parts for $20 and it worked.

Thx again to everyone who pitched in and gave me some direction when I hit multiple dead ends.
