Yes check the fuse, it could be a bad connection going to the headlight which may also blow the fuse.

I have a 2003 Pontiac Vibe and my low beams stopped working. High beams, turn signals and fog lights work fine. We changed the bulbs, the fuse, and replaced the headlamp switch on the steering colum. Any...

When you say fuses does that include relays, they're the black boxes located in the fuse panel. I would check the manual and see if there is a relay for the low beams, and/or for the right-left side

Prius high beam lights work but low beam lights do not work?

On a 2008 Prius, If both High beams work but only one side has working low beams, then it is most likely a fuse. So before breaking your knuckles to change the bulb, check the fuse first. I found out the hard way as my mom distressed to me that her drivers side headlights were out. So without checking to see if low and high were working, I proceeded to remove and replace the bulb - ouch! There are 4 10 amp fuses that protect the circuits for low/high beam function. They are under the hood in the fuse box on the drivers side and they are marked on the box cover. Check them before changing the bulb.

I have a 2006 ford escape and the passenger head light low beam will not work. Tried replacing the bulb, and check fuses nothing is working.. what else can I try?

Both your low beam and your high beam is protected by the same fuse, so it makes sense that the fuse is OK if the high beam is working on the passenger side. There are 3 fuses for the headlamps. Fuse #13 in the Battery Junction Box (20 Amp). If this fuse is blown, the headlamp relay will not have any power and neither high nor low beam on either side will work (you will have no headlamps at all) Then there is Fuses #2 and #3 (15 Amp) in the Battery Junction Box. #2 goes to the left low and high beam and #3 goes to the right low and high beam.
The headlamp switch uses a SINGLE CIRCUIT to control BOTH sides at the same time, so if one side works, the switch cannot be the problem. The headlamp relay provides power for fuses #2 and #3 and we already ascertained that these fuses must have power since we have working lights on both sides, so the relay cannot be the problem. A replacement bulb has already been tried, so that pretty much leaves us with a bad lamp socket. (Most likely cause) or a bad connection at splice #S122, which is located in the main wiring harness near the breakout for the left headlamp. (RED/BLACK wire)

it is most likely a blown fuse,the fuse box is usually under the hood also check the low beam relay,it may also be in the fuse box,if you have a test light see if there is any power to the low beam at the bulbs,if they are H4 bulbs it is the center terminal,also check for any loose wires or connector plugs,,,,,hope this helps......cheers

There should be separate relays for the low and high beams. located in the fuse box, probably under the hood. they look like plug-in small rectangular black boxes.

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.
