Check your relays to see if the left/right sides are controlled separately by their own relays. If so, swap the L/R relays to see if the problem moves with the relay. If not, put them back and try again since this kind of problem can be caused by corrosion on the blade contacts or their female mates. Relays may not draw enouigh current to keep the contacts clean.

High beams work for both lights, 1 low beam does not


Check for power with a test light with the light connected. If you have power then its the ground. If no power then you will need to trace the wire back to find break. As I recall they did have seperate fuse for left and right headlight high & low beam. Also did you get a defective new bulb?

I have a 2006 civic SI. DRL indicator is on, driver side low and high beam ok. Passenger side low beam ok but DRL and hi beam not working. Any help is appreciated.


When either the high or low beam light is out in either side, DRL (daytime running lights) indicator will come on. When one bulb goes out, that's a clue the opposite bulb will burn out soon, so its best to replace both bulbs. If it was a fuse issue, both left and right side would be out. If driver side is OK but passenger side is not, then its a bulb issue. A 2006 Honda civic takes 9006 (HB4) low beam bulbs and 9005 (HB3) high beam bulbs. Cheapest is online from Walmart site-2-store. After procuring, wear latex, vinyl, or ANY gloves to keep your (corrosive) oil skin from coming in contact with headlight glass bulbs. Your skin oil will chemically react and cause shorter life span on glass bulbs. Instruction don't tell you this, so you handle with your hands, then need to replace bulbs 3 years later instead of 5 years (or more) in the future. With gloves on, pop the hood and look behind each headlight. Turn counter clockwise to unlock headlight bulb holders. Its a quarter to half turn to unlock bulb holder lock. Replace one bulb at a time so you don't confuse high beam from low beam. The wire has a tab you need to lift to pull out & disconnect wire connector. You might need a slim narrow-**** (NOT phillips) screwdriver to lift the tab; or use your house key. Snap the wire connector to the new bulb, then twist into headlight housing to secure bulb holders, then move on to the next bulb to repeat the procedure. Pict below, 9005 high beam is on the left, 9006 low beam is on the right. Handle by grasping the plastic base, not the glass bulbs. The raised potrusion on the bottom center is where the tab locks onto wire connector. Replace all 4 bulbs now, but in the future, its likely the low beam will wear out before the high beam. In the future, replace only the pair, not all 4. The factory installs inferior bulbs that go out sooner, hoping you'll take to dealership and they ******** you with higher parts-n-labor fees. As opposed to Walmart online site-2-store, it would cost you AT LEAST triple in parts & labor from dealership to replace all 4 headlight bulbs :-(

I have a mazda 6 that has a headlight problem, low beams do not work and high beams do. It started with one light goning out and next time i started the car the second one went out. Also front makers went...


if your vehicle has H4 headlight bulbs fitted you will find that they have both high & low beam filaments in them,what has most likely happened is that the low beam filaments are blown & the bulbs need to be replaced, also you may find that high & low beam circuits are on separate fuses, & also the front markers may have there own fuse check the fuses as well.......hope this helps......cheers.

Hello, I have a headlight problem on a 2004 chey calvalier. All of my lights work except low beam on drivers side. Fuses on left and right headlights are good. I've switched bulbs as well and nothing...


I would focus on the connections going to that head light for the low beam. I agree, it is not the switch, otherwise other side low beam would not be working. It is most likely bad bulb inlet( if it i separated bulbs for high and low) or it is the connection going to the low beam that operates it. Hope this helps. Don't waste your time on switch, it is not that.

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)

For Audi A4 the fuse box is located on the left side of dashboard behind a plastic cover (for left hand steering wheel vehicle). On inner face of the plastic cover you will find the fuse diagram.
First fuse on first row from left upper corner is Fuse Nr.20 = F20 (15A) - RH headlamp low beam, headlamp adjustment.
First fuse on second row from left upper corner is Fuse Nr.21 = F21 (15A) - LH headlamp low beam, headlamp adjustment.

98 volvo S70 low beam bulb replaced still no light


Easiest way would be to go back to where you bought it and make sure the bulb is installed that you bought....and show them. Ask if you can get a new bulb and change it in front of him. Call the dealership and talk to parts, ask if, indeed the hi and lo are interchangeable.
