Only low beam headlights work, highbeams good. Replaced bulbs and check fuses and still have same issue.

Check fuses first!

Check for 12VDC at the connector with your high beams on. Could be the wiring or the connector and no they run on the same fuse.

Well the turn signals are a different circuit.
Usually the common problem with one headlight is the ground circuit.
Both the high and low beam use the same ground. I would check for power for each circuit and a good ground at the light socket.

DAYTIME RUNNING LIGHT MODULES CAUSE A PROBLEM LIKE THAT

If your highbeams are working fine, you must be referring to your low beams not working I would simply check the 2 bulbs and make sure the low beam filament is good, theres a strong possibility that your BOTH low beam filaments are bad and require replacement of both headlight bulbs to get them working again its a very simple repair.....

If your highbeams work theres a strong possibility that BOTH your headlight bulbs the low beam filament is burned out, if the highbeams dont work either check all related wiring and fuses for the headlights also the headlight switch on your steering column....

AT FUSE TERMINAL #45 TO THE RIGHT OF THE HIGH BEAM RELAY AS YOU ARE LOOKING INTO THE ENGINE COMPARTMENT FROM THE FRONT OF THE VEHICLE. THERE IS A 15 AMP FUSE, PULL IT AND SEE IF IT IS BAD. IF IT IS REPLACE IT. THIS IS THE FUSE FOR THE HIGH BEAM RELAY.

Hi,
With the low beam switched on, see if you're getting power at the wire connection to the bulbs. If so, there may be a bulb grounding issue. If not, there may be a light dimmer switch issue. Just a quick observation but I hope it helps.
Good luck!

Hi,
It has been because the lamp bulb or halogen lamp module has reached the end of its serviceable life, not because of any wiring problems. Low beam burns out first because it is on the most. If low beam is lost simultaneously in both headlights, I would check fuse first, then the headlight switch. If low beam is lost on one side only, it is almost always going to be due to the bulb or lamp module needing to be replaced. In that case, replace them in both headlights because the other one will be going kaput in short order, as well.
Most like the low beam filiment is bad but the high beam filiment is still good, try replacing bulb. If replacing bulb does not fix problem then you probably have voltage problems and should check the voltage reading and the plug.
OR
isolate the wire that comes from the headlight switch to the headlamp bulbs for low beam and check to see if there is a short in the wire. You can find this wire by using a test light turn on the key and get a good ground with the test light poke the wire and see if the test light illunimates with the headlight switch on.
check the wires, and check the fuse for your lowbeams. could of blown a fuse on your lows, but your highs will still work.

The fuse box is located in the engine compartment,on the driver's side. Has thumb-screw retained cover.
Thanks for contacting fixya.com

check the lowbeam headlight relay located in the fuse panel in the engine compartment near the battery.
