Where is the headlight relay on a 2004 Hyundai accent

Check the bulbs could be blown low beam

Now you have to start the wiring from the motherboard to have the wiring run correct. Easy fix. Junkyard should have a light for your car.

Get a schematic and trace out the power source to those devices not working.

have you checked the flasher relay

headlight switch or high beam switch if you have one

Problem is either wiring or the bulbs... evident.

the grounds may be bad they are behind headlamps but more than likely it is the switch

Some imports require the entire light assembly to be removed in order to replace headlamps. Look to see if there are angled rods on the back side of the light assembly. If so, see if the can be pulled straight up towards the hood of the car. When they are released the headlight will be able to come forward. Good luck. Hope this helps.

Under the dash fuse box ,fuse 15 (TCM ECT) is a combination of cluster, heater and headlights.probably a relay fuse!!!!! fuse 16is a relay fuse.

Lihgting switch must also be checked
