SOURCE: 93 jeep cherokee headlights won't work

Wiring can get complicated, however that is not a super complicated system (gets bad on the 96 and newer models) You should be able to test circuits at the switch. Be aware that if this has a "Daylite Running Lamp" system it may add some additional circuits. You're best bet is your local library for info. They should have "All Data" or something simular or possibly a Factory manual.
Good luck with that. Let me know how it works for you?

Where do I locate the fuse of the headlights in a 1984 jeep


Don't believe there is one for headlights. Your jeep is too darn old: I can see wiring diagrams going back to 1986 at a site, so I looked at one for an '86 CJ7. Unfortunately not a complete headlight wiring diagram, however, so you're getting a two bit answer, with inflation worth about 10 cents. lol.

The headlight switch gets power from a fusible link (Fuse link A) that looks like it may be located on the starter solenoid terminal- two fuse links- A & B, there somewhere. But this same fusible link A also supplies power to the fuse block with the park/tail lamps, hazards, brake lights, and a couple others. So if you have stop lights and park lights, then the fusible link is good, so you should have power to the headlight switch. Neither the fuse block, nor the instrumentation diagram, shows any fuses for the headlights. A lot of older vehicles did not have headlamp fuses, because the light switch had a built-in circuit breaker.

My guess is you have a bad dimmer switch, or the connection there may be bad. Or check if you have power to the headlight socket with the light switch on, and if you do, there may be a headlight ground problem.

I have problem with a fordexpalorar 1996 v6


First, make sure that you have power to the headlight. There are a few ways of doing this. Then make sure that the headlight itself is not burned-out. If this doesn't work, then the only other possibility is that there is a bare spot on a wire that is causing this to short-out. If this is the case, then the other headlight wouldn't be working and you will probably blow fuses.

I have a 93 jeep laredo, the daytime running lights are staying on even when the vehicle is turned off. The dimmer switch for the high beams doesn't work anymore. I am thinking if I replace the dimmer...


93 Jeep Loredos didn't have daytime running lights from the factory. It has to be an after market set up so I would trace wires to power and ground. It probably has a connection to the headlight switch wires through some sort of solenoid.

Fuse 16 keeps blowing when ignition is turned on (fuse for headlights), 1996 honda accord.


You have a short somewhere in the headlight wiring. I would start by unplugging the headlights and see if it still blows. If so then you might need to trace the wiring back (with the negative battery unplugged) and find where the wires are touching. If it doesn't blow with the headlights unplugged then you should just need to replace the headlights.

Headlights will not turn on S-10 2001


Assuming you've checked the bulbs themselves, check the fuse in the fusebox in the dash. If that's ok, check the large fuse in the black box under the hood. If it's still not working you may need a new headlight switch, or have a wiring issue. IIR those were prone to the headlight switch burning out. I seem to remember it being about $80, so go over the wiring, the bulbs and fuses first.

To check if it's the switch or not, try turning on the interior lights with it, and run the dimmer up and down, and then try just the parking lights. The switch should click nicely, and not feel warm/hot to the touch.

Can i use h4 -130/80cp-60/55w halogen lights on my 2002 kia spectra


hi,

you can try to see if the kias headlight wiring and assmeblies will take it. it may blow a fuse. first leave the stock headlight on for ten minutes to see how hot the composite headlight assembly gets. replace one on the passenger side with the hotter bulb and observe how hot the wires and composite headlamp assembly is getting. it it gets to hot to handle then I wouldnt do it. if its okay then replace them both, feel the main headlight wires to make sure theyre not to hot either. leave them on with the replacements for another 10 minutes, the stock fuse would blow in that time. You may have to go up 5 amps on the headlight fuses but absolutely no more. have you seen the other type of headlights HID's?
you might want to try that option as well, and I think those are are designed to replace stock installations better. use your discretion and be careful. the last thing you want is headlights using their own candlepower! lol,

1996 Mark VIII. Turn ignition off and headlights/tail lights stay on for hours. What could be the problem. Help I have pulled the positive cable from the battery.


Problem is most likely the headlight delay switch. See if you can find a used one. It seems that the timing in the switch is off...
