Your actual headlight lamp switch may be out or shorted. I had this issue with my Dodge Dakota (headlights wouldn't work but could hold down the highbeams by rigging it) but my headlight switch pulls out from console. If that is the case, take the dash faceplates off and access your headlamp switch. Remember where all screws go. There is a connecter that disconnects and the actual inlet connecter is most likely the culprit. Look for blackening or melted/burnt plastic

Are you sure bulbs are good? If low beam are running lights as well, might be set in series. If one bulb goes out, no light at all. This was the case for a 2003 toyota camry. Was wired in series.

Ok look under the bagtterry tray, there is a black box bolted to the body, it is the headlight ground and has a really bad tendency to corode due to the design.

SOURCE: High beams work but low beams do not. Fuses seem to be good

Hi

I would start with the dimmer switch if you know the lights are good dimmer switches do this you will lose your high beam or you will lose your low beam when they go bad.

SOURCE: high beams dont work

Could be that your high beam light's are burnt out and need to be replaced. When you say the the switch is new you mean the lever on the stearing collum is new right?? Good luck

SOURCE: low beam not working but high beam is-Pontiac Vibe 2005

I have heard it could be the Daylight Running Light module located under the dash above the brake pedal. The module controls both the daytime running lights and the low beam lights. The high beams are independent of this module.

I have the same problem. I am trying to buy a new module.

Is there any fuses or relays that are not in the fuse box on a 2002 buick rendezvousfor the bright lights

The high and low beam lights use the same power source, so if the low beams work the high beams have power.
There is a low and high beam relay controlled by the dimmer switch.
If the low beams work and the high beams don't, and the bulbs are good, check the dimmer switch and the high beam relay.

The low beams dont work but the high beams do. we have changed the bulbs and nothing changed

Hi, it might be a fuse that is blown as the high beam and low beam work on 2 different circuits because of the current that each circuit use. If all the fuses are fine you should look for power on the light socket where it connects to the bulb. If there is no power you will need to see if you have power from the switch. If the switch does not give power to the wire leading to the relay the switch can be replaced. If there is power from the switch to the relay, but not from the relay to the lights you need to replace the relay otherwise it might be that you have a bad connection or broken wire

My headlights dont work,.all other lights are fine though,.is it the fuses or the bulbs? im not sure what fuses they would be,.there seem to be different ones for the same thing

do your flash to pass lamps light when you pull the stalk towards you? If yes, the bulbs are ok.
Do the hig beams work?
Your headlamps have sepaerate fuses for each headlamp and you have a low beam relay and a high beam relay under the hood in the black box.
If everything is out, I suspect a bad headlamp switch.
Check car-part.com and look on page with * for cheapest price.

Your owner manual will identify fuses & relays.

PS, You did not recently instal high current bulbs did you? If yes, put originals back in.

HEADLAMPS

The voltage is supplied to the lamp switch through a fuse. This fuse is located in the central junction box in the left-hand footwell.
When the headlamps are switched on, a voltage is supplied to the high beam/low beam switch and to the low beam relay. The relay for the low beam is located in the battery junction box (BJB) in the engine compartment.
If the high beam/low beam switch is set to "low beam", then a voltage is supplied through the low beam relay to the low beam part of the headlamp assembly. The left and right-hand low beams are fused separately. The fuses are located in the battery junction box (BJB) in the engine compartment.
If the high beam/low beam switch is set to "high beam", then a voltage is supplied through the high beam relay to the high beam part of the headlamp assembly. The left and right-hand high beams are fused separately. The fuses are located in the battery junction box (BJB) in the engine compartment.

05 Jeep Wrangler High Beams Work, Low Beams dont

There are no relays for the headlights. Your problem could be from the headlight switch. You would have to check and see if you have power coming out of the switch on the low beam side. Check with a test light.
