Possibly two bulbs, possibly the switch. Get it diagnosed.
check your fuses for your headlights. i have a '97 accord and installed aftermarket headlights and one day one of my lowbeams wouldn't work but my high beams would be on with my low beams on, and when i switched for the highbeams, my low beams would both go out. you can get a thing at shucks, or even, to check the fuse to see if it's working, very simple to use. :)
Did you try replacing the one headlight that only works on the high beam mode?
First check to see if you have a relay. If it dont have one, the problem lies on the dimmer switch. Locate the dimmer switch. On some vehicles the dimmer switch is part of your headlight switch.
If only one of your headlights is affected then it probably isn't a fuse or relay. A light that is both a low beam and a high beam has two filaments. One of the filaments is probably broken. Replace the headlight and it should fix the problem.
i did replace the lamp on a 96 sunfire and the low beam still does not function. highbeams work fine, but no low beams on both headlights now.
I have a similar problem. Both headlights low beam filaments on my WRX STi had blown and the replacement low beam filaments blew too??? So I've still only got high beam which is fine but other drivers are getting a wee bit annoyed (and rightly so)All fuses are good and correct factory ampage. The new bulbs are H4's which is the factory correct bulbs yet low beam filaments gone on both bulbs. I'm bewildered...
Fuse or bulbs burned out. On most they are separate bulbs or high beam filament is broken if 2 in 1 bulbs.
First check the bulbs, if the bulbs are good I would suspect the high/low beam switch is bad.
Check your owners manual.
Bad bulbs?Bad Hi-low switch?
Your high beams work but your low beams do not because the switch is broken that switches between high and low beams. Electrical switches wear out.
Headlights have two filaments; one for low beams and one for high beams. There is a good chance that the low beams are burnt out. This doesn't necessarily mean that the high beams won't work. However, it's not too common for both low beams to burn out at the same time. Of course, it could be a fluke. I would replace the headlights with new ones and then go from there.
Try pushing the high beam lever forward. In some cars pulling this towards the driver only "flashes" the high beams, like for warning another driver. To make the high beams remain on usually requires the lever to be pushed forward. Either that or you have a defective switch in the turn lever that needs to be replaced.
Bad bulbs Bad dimmer switch
If low beams do not work and the high beams of a Mitsubishi Eclipse do, it is probably due to a corroded connector. Simply clean the connector and add some petroleum jelly to the terminals.
Take your car in to have it checked. Turn signals should work without high beams.
Does the car have fog lights? I have a 2003 Sunfire that the high beams would not work on. This was caused by a short in the fog light wiring. I had the fog lights rewired separate from the harness (about $100) and the problem was fixed.
As a guess both low beams are burnt out The daytime running and high beams are the same light filament. Or the fuse or the relay for the low beams.
check the bulb low bean burns out before high beams
check the wiring at the hi-low switch.
your bulbs are burnt out. when you switch on the high beams its only the high beams. but when you flash your brights it lights up both high and low beams.
check all the wires that ground coming from the headlight
Bulbs are burnt. replace both. low and high are together in the same bulb.
hi-beam switch is faulty
The reasons that your high beams may not work could be the cause of a few factors. One, be sure to check the fuse that controls the high beams, it is separate from the fuse that controls the low beams. Next, if that doesn't work, go ahead and check the ground wires, a lot of the lighting problems in my VW was the cause of the ground wires. If this doesn''t work for you consider that the high beams could be burned out, but I figure that if both the high beams don't work that isn't the case. Then you would need to take into account the switch located in the steering column that turns the beams on and off is broken. Then if none of the above works you have an electrical short that needs to be fixed the best way to fix this probleem is to replace all the wiring that origionates from the high beams. Iknow this answer is a little long winded but this the way I do it to save the most money in the long run. Good Luck!
The low beams turn off when you switch to high beams. If the lights don't work with the high beams on either both high beams are blown or the high beam circuit has problems and you'll need to figure them out.
Check the dimmer switch and the electrical connections.
Bulbs burned out? Bad switch? Blown fuse in power distribution box
Replace the bulb. The low beams and high beams use separate parts inside the bulb. If replacing the bulb does not fix the problem, check the fuses.
I'm not sure what you mean by that. Usually low beams have its own coil, high beams have its own. They work on separate cirtcuits.
Bad bulbs or multifunction switch
