Kia Optima 2005. Driving down the road. At the same time both low beams went out.
New fuse in panel fuse box. New fuse in the engine compartment fuse box. New light bulbs on both sides (no didn’t touch with fingers). Still, low beams don’t work. Note, both high beams work just fine. HELP!
First verify that the switch is energizing the relay in both positions by turning the low beams on and then pulling up the relay--does it click? If not, replace the switch. If yes, next check for power on the red wire as it comes out of the column. Switch on, no power--replace the switch. If power, check for power at the head-low fuse in the engine compartment fuse box. No power--find break in wire. If power, check for power on the yellow/red wire as it comes out of the fuse box. No power--repair fuse box. Power--check for power at lamps--same wire. No power--repair yellow/red wire.
You should get the wiring diagram for 2013. You might find it by getting a free account at autozone.com or at bbbindustries. I start there. If the headlights all run through one fuse, then check that fuse. If there are multiple fuses, suspect the multi-function switch or maybe the relay.
