Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
Do you have a voltmeter to check the circuit if I guide you?
I will reply here if you have a voltmeter.
Good, first check is turn on the lights and check the yellow wires for 12 volts at the bulb connectors. Check your meter on the battery, set it so you see 12.2 - 13 volts when you measure.
Let me know what you find when you measure from the yellow wire to the negative battery terminal with the headlight switch on.
Unplug a bulb and see if you have 12 volts with the meter between the yellow wire and the negative battery post with the light switch on. If nothing then we go back to the relay but if you have 12 volts it may be the bulb.
Let me know if you measure 0 volts or 12 volts.
OK, then if you think you made contact to the yellow wire connection back up to the low beam relay and put a paperclip between the #30 and #87 pin socket of the relay. The numbers should be marked on the relay. Let me known what you see with the key on and the bulbs plugged in.
Not the fuse but you are pulling the relay for the low beams, you can also check the #5 fuse in the Passenger box to see if it is blown but testing the points on the back of the fuse to see if you have 12 volts on both of the points.
All you need is your voltmeter.
Each fuse has two testpoints on the back, measure between that and the negative batter post. The low headlight fuse is in the inside fuse block, the diagram is here (click) the relay for the high and low beam is in the under hood box. (click) check the fuse and if it is good check the relays with a paperclip.
