Headlight Problem

I have a 1995 YJ Rio Grande. When I turn the headlights on, they stay on for 3-5 minuts then go out, yes, the markers all stay on. Then they will come back on after 10-30 seconds, then go off again after 30-45 seconds, then come back on in 10-30 and keep cycling this way. Toggling the headlight switch makes no difference, turn signals still work. What's going on? Bad relay? If so, where is it located? I don't have a decent wiring diagram...Haynes...so any help woulf be appreciated.

Was there some type of remote start or aftermarket alarm on the jeep? If so get someone to unhook it.

If not I'd start at testing the headlight switch. Common to fail in the yj's

Headlight Problem

No aftermarket stuff on it. I also recently replaced the hi/lo beam switch, but the hi/lo toggles correctly and the headlights fo out whether it's on hi or lo...how could the switch be doing it? I would think that if it's the switch it would simply fail on or off constantly...it's the intermittent factor that has me stumped.

Something in your wiring is bad, possibly a bad ground.

Headlight Problem

Herbie, that makes sense....Where is the circuit breaker? This is the first Jeep I've worked on in 35 years, and the last one was a Willy's.

i do not know off hand where it would be found however typicaly the head light circuit on a vehicle has an a self resetting circuit breaker so your not entirely left in the dark (that has always been the way in the past)on a side note i do not know how to respond to private messages as my computor blocks that stuff and i am better at understanding how it works than how to work it lol!!!

Your squirrels are getting tired, remember they are 17 years old...

What is the life expectancy of a squirrel anyways?

Look in your PDB box on the fender by the battery, also sometimes the headlight switch has the circuit breaker built into it and the only way to replace is to replace the headlight switch.

Just looked in the repair manual it shows a circuit breaker built into the headlight switch so looks like time to replace headlight switch. Hope this helps
