My passenger side low beam headlight recently went off on me. ... I've changed the bulb again, and changed the fuse just in case, but .... My driver side headlight wire got loose so when i hit a bump at night if would flicker. ... When you notice one side not working (Low or High beam) it could be the module. Headlight replacement

The daytime lights run off the highbeam circuit on reduced voltage. If the lowbeam is not operational, take a look at the plug at the headlight and inspect for looseness. If tight, inspect for a constant ground and a 12v power supply with the headlights turned on low beam at the headlight connector. repair a necessary

low beam not working could be relay or bad contact at stork control. Fog lights should only work with park lights on. not supposed to be on with headlights like in the movies. This is illeagle in australia to have head lighs and fog lights on together as well as being dangerous to other motorists

For the low beam problem, Swap relays 45 & 46 in the underhood fuse panel. Relay 46 is for the Low Beams. If that fixes the light, replace the relay that cam out of position 46.
Since the high mounted brake light is working, that indicates that the brake switch is good. You need to check the bulbs in the rear tail light assembly, if they are good, check fuse #34.

Power for the headlights goes directly from the battery to the headlight switch, then to the dip/flash switch on the column.

The fact that the high beams are working but not the low beam says the problem is somewhere between the switch on the column and the headlights.

Either the switch has failed, or there's a broken wire or open connector in the wiring harness.

The wiring for the low beams is a blue wire with red tracer. Check the wires coming off the steering column with a voltmeter to see if the problem is with the switch or the wiring forward of the steering column.

If you have power at the connector harness coming off the switch, then keep working forward to find the open circuit.

Make sure you use the right light because the high beams and low beams use different lights. I think the low beam is H4531 and the high is H4532.

the filament on the low beam burnt out. but the high beam didn't. You have a filament for each. 1 for high beam and 1 for low beam in the same light bulb. You need a new head light.

THERE ARE FUSES THAT PROTECT THE HEADLIGHT CIRCUITS. CHECK TO SEE IF THE FUSES ARE GOOD. THIS SHOULD HELP YOU OUT REAL QUICK. THANKS FOR USING FIX-YA AND FOR AN HONEST RATING AS WELL. PLEASE KEEP ME POSTED. GOOD LUCK

But the assumption is that both went out at the same time. I would say it is likely that one low beam went out, wasn't noticed, then the other low beam went out, which couldn't be missed.

I would say replace headlights/lamps.

perhaps i missed something here... lowbeams and daytime lights are about the same.... be that as it may... the merely obvious thing is that the low beams are burnt out.... next thing would be that the relay for the day time lights could be defective... it's often mounted on the firewall.
