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.

Low beam head lights not working - The low beams, both stopped working. The high beams work fine. I checked the fuses and all 4 are good. I even swapped the low and high beam fises just in case. No...


if the fuses are good then you need to check for power and ground at the headlight plug that attaches to the headlight bulb if you have a good power and ground there and the connections are good then the bulbs are both no good.or if you can tell the bulbs are burnt out by looking at them then you don`t have to check powers and grounds.you also can directly feed power and ground to the bulb and check both the terminals for high beam and low beam as you cannot tell which is which by looking at the terminals

Low beam headlight are not working. high beams and fogs lamps work fine. is there a fuse for a controller?both low beams stopped working at the same time so i don't think it the fuse for the headlamps.


The problem could be the headlamp switch.
You are right about the fuses.There is one for the LH high/low and one for the RH high/low.
Have you tried turning on the lamps manually with the switch?

My low headlight in my envoy 2002 is down i checked the fuse and still no luck


If this low beam is on one headlight only, I would say that the light is burnt out. Both hi and low beams are on the same bulb.The bulb has 2 filiments, one low and one hi. If you get just one light out , it is most likely a bulb. If you get both sides not working at the same time, it could be something else. You have checked the fuses and deemed them to be o/k. Then you should be checking for headlight bulbs.

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.

Low beam headlights not working on 2004 Pontiac Montana extended


You headlight lamp have a diffuser mechanism which allows it to flip between the hight beam and low beam feature of the bulb. In fact, you high beam will function even if the low beam is not working.

I would recommend the purchase of the new headlight lamp. It would cost you you any where from $15.00 per unit to get a replacement lamp
