2003 hyundai elantra low beams not working but the high beams and parking lights are, why, help

Ask the Hyundai people. They shouldn't charge you for that information.

Well, the problem is that I dont know the reason, you should investigate. There could be issues with lamps (must get new) or electricity problems (must head to auto-service)

First it is possible that both low beam filaments in bulb are burnt. Check fuses for low beam before replacing the bulbs.

There is no adjustment for high beams, they follow suit with the low beams.

The little parking light (also known as a city light) is in a plastic connector below the low beam lamp that simply slides out of the headlight assembly.

Grasp the plastic connector and pull back away from the headlight assembly and you will be able to unplug the light from the connector for replacement.

when the low beams quit try switching from high to low and back and see if low beams stay on, if they do it may be the dimmer switch, if that doesn't change anything suspect the headlight switch.

Bad headlight switch that needs replacing

thats it my freind one on each side/Plaes rate my response thank you very much

its all the same the headlight is a complete unit you adjust both/ look for screws behind the headlight one each side one is for horizontal annd the other is for vertical Please rate my response thank you very much

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.
