So, what you are saying is that it's probably the wiring, correct? Sorry for the questions, I do know a lot about fixing cars, but when it comes to the wiring, yeah, not so much.

No, I didn't say it was probably anything. You admit you don't know much about cars but you are trying to diagnose a complicated electrical problem. This is really beyond your ability and you will need a shop to diagnose it for you.

No, I didn't say I didn't know a lot about fixing cars, I said "I do" know a lot about fixing them, but when it comes to the wiring, I don't. I was trying to see if it could be something other then the wiring, if anyone else had been through this, sorry you think I am totally oblivious, but thank you for your help.

Nobody said you were oblivious but if you think you are capable of following the circuit on a wiring diagram, I'll give you one.
Does your truck have daytime running lights?

No my jeep only has the running lights that you turn on with the same switch as the headlights and they work just fine, it's just the headlights that are not coming on. And yes, I am perfectly capable of following the circuit on a wiring diagram and would appreciate if you could do that, thanks.

Thank you so much, that helps me a ton. I really appreciate your help and hopefully other people are just as grateful for you help. If I have any other questions after we go through all of this, I will be back, but I am really hoping I don't have any more.

My low beams will not work, but high beams do. I have changed the bulbs, cleaned the connections, checked the fuses. What else could it be or should I look for?

Welcome to the forum. My first thought is the dimmer switch. There may be a multiwire connector under the dash, close to steering column, for circuits going to and from the steering column. The violet wire carries voltage for low beam.

On an Intermittent basis when I pull the headlight switch, the lights won't come on. Instead the lights on the instrument panel all light up; the high beam indicator, the left and right signal indicators, etc.
I thought it might be a short, but how do you find it?

Hi, thanks for the donation. The problem maybe the wiring circuit or dimmer switch. If in the steering column, there should be a multiwire connector, under the dash, close to column, for circuits going to and from the column. Tan wire with black tracer is voltage feed from headlamp switch to dimmer. Red wire with orange tracer, is voltage feed from dimmer to high-beam headlamp. Violet wire with white tracer is voltage from dimmer to low beam head lamp. You need to check voltage when problem is ongoing. Also chek grounds.

HI,

Thanks. RE: You need to check voltage when problem is ongoing. Also chek grounds.

What would show on the voltage when problem is present. No voltage low voltage? Where are the grounds?

Close to battery voltage, reading, on voltage circuits. There is a ground circuit at the headlamp connector, black wire. One way to check ground, is to take connector loose. Use a testlite connected to battery voltage, touch the terminal for the black wire. If the lite comes on, the ground is good.

I TURNED ON MY HEADLIGHTS AND THE PARKING LIGHTS CAME ON BUT NO HEADLIGHTS. I TURNED ON THE HI BEAMS AND THEY WORKED BUT AM UNABLE TO SWITCH BACK TO LOW BEAM. IT SEEMS LOW BEAM IS NOT WORKING. CHECKED FUSES & THEY LOOK OK.

Hey there,

Jeep Cherokee Sport 4 wheel drive automatic with about 150,000 miles. I had the radiator replaced a few months ago and air conditioner serviced as far as any repairs. About three days ago I left for work in the morning and my parking lights came on but no headlights. After the jeep ran for about five minutes they came on. This has happened to me every morning now and just this afternoon they will not come on at all only the parking lights come on. If I pull the high beam switch to the momentary position to the rear they will come on momentarily but if I push the switch forward to keep them on they dont come on. I checked a couple fuses but they seemed okay. Any suggestions?

Hi, with or without drl? I'd have to check voltage circuits to and from, the headlamp switch, when the problem occurs. If that checks out, check voltage from dimmer switch. You can't see voltage, use a voltage tester. We can give you wiring diagrams and wiring colors, but, you have to do the actual testing.
