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 Walmart, 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...

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.
Why would the high beams on a 1994 Thunderbird work when the low beams do not?
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.
Why would Headlights turn signals and interior lights not work but the high beams work only when you hold the high beam lever back what would cause this problem?
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.

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.

Why won't high beams work on 1974 VW bug?
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!
Why do both headlights go out when you turn brights on in 1994 jeep cherokee?
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.

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.
