My brights work but not the heade light - Hyundai Motor 2002 Elantra

There could be several potential causes for both the tail lights and headlights not working and for the headlights turning on the brights when the vehicle is placed in gear. Some possible causes include:

1. A blown fuse: If a fuse has blown, it can cause the lights to stop working. Check the fuse box and replace any blown fuses.
2. A problem with the wiring: If the wiring has become damaged or has come loose, it could cause issues with the lights.
3. A malfunctioning light switch: The light switch might not be functioning properly, which could cause the lights to not work.
4. A problem with the headlight switch: If the headlight switch is malfunctioning, it could cause the headlights to turn on the brights when the vehicle is placed in gear.
5. A problem with the dimmer switch: If the dimmer switch is not functioning properly, it could cause the headlights to turn on the brights when the vehicle is placed in gear.

It's recommended to have a mechanic diagnose the issue to determine the cause and recommend the necessary repairs.

pull back on turn signal switch??

Switch.

Sounds like you lost your ground to both head lights. One for each side. They ground on the radiator core support.

not sure about that one but there is a dimmer wheel by the light switch. move it up and down to dim and brighten the dask lights/cluster. wheel may need replacing. also work the lights on and off switch manually to see if there every thing works smooth or hopes from dim to brite.

check your fuse box. High beams (brights) usually have their own fuse. Otherwise it could be a problem with your switch (i assume its one of the arms behind your steering wheel) buyt i would pull the fuse first. Refer to the diagram for your specific car. fuses are cheap and you can tell theyre blown when you pull them out (a break in the fuse)

There are relays for the head lights,but see if the bright lights work also,the bulbs maybe blown,not uncommon for both to blow,then there is the headlight switch,if the brights do not work,it is most likely the headlight switch giving the problem.

It seems like you have a bad ground wire or a short.

did you check if yourl ow beams. might be burn out that is usually the case if the high beams work that is usually the case if the high beams work take them off buy new ones and try them just make sure you dont touch the new ones with sweaty hands that migh mess them up

1990 Jeep Wrangler. Driving with lights on for 10 - 15 minutes. First the dash lights go out followed by the headlight and tail lights. If you pull the dimmer switch back (like you would to flash your brights at someone) the head lights will come on and as long as you continue to pull back on the dimmer switch the head lights will stay on bright.
