Got in the car tonight and turned on the lights but stayed in the dark. High beams are both fine. No low beam but day beam works fine. Everything worked two days ago. Ideas?

It could be driving lights mode instead of low beam. Check connections.

Well the high and low beam lamps use the same fuses, and the dimmer switch handles the ground circuit. So I would check the dimmer switch if both high beam bulbs are ok.

headlight relay or switch

Common problem, there is a headlight relay in the power distribution center under the hood that needs changed out.

There could be a fuse for each low beam light either under the hood or under the dash. If not, then prob both low beams are bad.

If you have daytime run lights, the following may be of help.

There is a daytime running light module that controls both low beams and the daytime running lights. The low beam bulbs may be OK. The high beams will work fine as they are not controlled through the module.

It may be possible to disable the daytime run lights by cutting the yellow wire going into the module and then connecting it to ground. Tape off the other end.

This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

I would say your light switch is either dirty or bad.

just replace the dimmer switch under the column its wore out on the low beam side

DID YOU CHECK THE BULBS?

If there is power there, then it has to be the bulbs. The trouble that most people have is, they don't see how both bulbs could burn out at once... and they're right. They don't. But you see vehicles with one headlight all the time. They don't know it unless you tell them or they happen to see it themselves. Then the second light burns out, and they think it's a major catastrophe, when in fact, it's just bulbs. The high beam still works because the bulb is double filament. The only other thing it can be is the dimmer switch, and since you switched it to high, it appears to be working. However, if it's not bulbs, it still could be the switch.

You probably have a faulty sentinel switch. It's supposed to shut off, has a bult in elctronic timer. Does it even have the sentinel switch?
