My left my left side headlight does not work the high beam work but the low beam does not work what could cause that

PAWEL IS A BOT. HE POSTS GENERIC ANSWERS. AND OVERLAYS NAME OF YOUR CAR. 82 GENRIC ANSWERS HIM
AND LIES ABOUT IGN SWITCH.
NOW YOUR CAR.! FACTS, ONLY, 1 CAR
LEARN TO USE THE DMM , CORRECTLY;
HEAD LAMPS ON.(SWITCH) NO KEY IS NEEDED FOR HL.
IS DRIVER LEFT OR RIGHT,? IN USA LEFT.
IS HIGH AND LOW BEAMS DEAD LEFT? No TOLD AT ALL.
PUT METER BLACK LEAD TO THE BATTERY NEG LUG
THEN PROBE RED TO ALL WIRES OF DEAD LAMP 1 BY 1.
12VDC IS GOOD 0 BAD
IF LAMP GROUND PIN READS 12VDC <<< GROUND FAILS.

LEFT LAMP USES GROUND LUG G101. IF R

CAR HAS DRL. SO DRL AND MANUAL LAMPS FAIL
HIGH , LOW , AND FLASH HIGH>? NOT TOLD
DOES ENGINE RUN? OMG NOT TOLD.
THIS CAR RUN HL RELAYS BY BCM CONTROLLER BRAIN


FUSE ARE ON THE OUTPUT OF ALL HL RELAYS
SO IF ALL FUSES INPUT(TOP) ARE DEAD,THAT MEANS
BCM IS FAILING. OR THE SWITCH TO IT.
OR FUSES BLOW TO BCM
WE SCAN THE PCM/BCM TO SE WHY.


HEAD LAMPS ON THE 4 FUSES ALL 4 RIGHT SIDE ARE
12VDC, IF NOT BCM IS MESSED UP, OR RELAY DEAD.
HE LOW BEAM RELAY RUNS BOTH SIDE
SAME WITH BEAM. A RELAY FOR IT.
DRL HOT ONLY IN DRL MODE.
DRL; HAS A SUN SENSOR (AUTO MODE)


BOTTOM HERE IS HEAD LAMPS.SIDE.

HEAD LAMPS ON USA WORK EVEN KEYOFF
SO DOES BCM TO DO THAT, MAIN BATTERY NOT DEAD

Check the wiring on that light. Also check the bulb with a couple of wires to the battery, or swap the bulb left to right to make sure the new bulb is okay.

I would check for the groundwire continuity

The high beam continues to work on both sides...I pulled the Driverside headlamp fuse and then both left and right beams lit up but very dim.

If you have standard halogen bulbs:

1. Burned out light bulb; or
2. Fried wires between the dashboard wiring harness and the headlight bulb connectors; or
3. Fried headlight bulb connectors.

If you have HEI emitters:

• Failed ballast.

Hi, check you bubble or replace it.

Check your connections at the wiring harness going to headlights for corrosion, sounds like high resistance somewhere, also make sure your ground wires are secure. It wouldn't be the alternator or the battery would be dead and not start the engine. Also shouldn't be any condensation in your head light assembly's or will cause bulbs to blow prematurely.

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 :-(

Power for the headlights on the Left side (High and low beam.) comes from the same fuse... The ORANGE wire and the ORANGE/BLACK are the same, they connect in the harness. If you only lack the 12v to make the light work connect them at the headlight assembly.

If your low beam also lacks ground the Left low beam ground is shared with the right low beam ground... Run a wire from left low beam DARK BLUE to right low beam DARK BLUE/WHITE.

If its not working now then your cursed, seek a witch doctor.

Try this to eliminate new bulbs for both sides:
With a partner behind the wheel:
PULL out the bulbs one at a time. Keep them plugged in. While you are holding the bulb - have your partner click and HOLD the High Beam Selection. This causes the Low Beam and High Beam filaments to both go on and stay on.
Check both sides this way.
While the bulbs are out, look at the filaments that did not illuminate. Are they broken, bent, or have indications they are burnt out?
You can also change to bulbs (left to right, right to left) and recheck using the above method of holding the high beam selector and checking the filaments.

Ill guarantee you have an electrical short on the left side of the headlight switch,circuit.From here its immpossible for me to go any further.Good Luck.,Get A Wiring diagram.
