I've encountered this several times on Kia products, The soultion is the headlight relay--not the control relays on the left of the steering column under the dash but the hihg voltage relay which ic only available from the kia dealer---yea , abummer but it's true ...
The first thing I would check would be the headlight fuses. (There may be one fuse per headlight.) Also, examine the headlights carefully for any damage.
The battery in my 1995 kia sephia had to be placed replaced and now I noticed water marks on top of brand new battery. What would cause the battery to overcharge?
There are separate fuses for each headlight, they should be in a fuse box which is normally located under the bonnet.
Bad headlight switch.
Headlights,interior lights stop working.checked all fuses. I would suspect the headlight switch and/or the electrical connection at the headlight switch is faulty.
Check fuses or headlight switch
A short to ground in the positive side of the headlight circuit. Most likely by a failed headlight switch. Ford is notorious for faulty healdight switches.
Overtightened, undertightened, distorted or damaged pan, something HIT the pan... who knows. It could be any number of problems.
Check fuses? Could be a bad headlight switch/ Could be an open in dimmer rheostat?
Headlight dimmer switch is defective
Check to see that all other lights work on the neon. Check for a headlight fuses, relay, and a bad switch. Check for any loose wiring that can cause power loss to the headlight.
Your wire connection to your headlights from your fuse box might be loose or broken somewhere. Try running a jumper wire from your headlights to the fuse box. If the headlight work when you try this, then your wiring has an open circuit and needs to be replaced, or fixed.
Usally located in the fuse block. this is normally on the driver side near the floor board. it would help to add the make model and year of vehicle.
Bad bulb? Bad socket? Bad wiring to socket?
Check fuses, check for a failed (and possibly melted) headlight switch.
2 fuses located at plug end. One. Needs to be replaced.
I'm thinkin' the headlight switch is at fault.
Is it possible one headlight has been burned out for a while, and the second one going made you notice it? If not, I would suggest the headlight switch as the next most likely part.
you might have a bad Flasher relay.
Check the plug-in for the trailer lights, if it has one. If not, check the Headlight switch. It probably has a burnt wire.
More than likely there is a grounded wire that would cause this. There may also be some blown fuses as well.
it was a recall on those models go to your Lincoln dealer and have the headlight switch replaced
i would check the wiring for cracks
