Lighting systems only one main beam headlight works

SOURCE: no driving or high beam headlights

Hi,

To my knowledge a 2003 Toyota Camry uses a dual filament halogen bulb, either by Osram, Philips or Sylavania. If on the dashboard, the blue indicator lits when the switch is moved to bright or the passlight is engaged but no headlight, then it could jut be busted bulb (or part of it since you still have driving/low beam). In some cases, it could be the relay that supplies power direct to the bulb. At other times, it could be fuse(s) assigned to high beam. At certain instances, it could be also a loose, corroded or burned connector.

Corrective measure for your concern would be to check the 2 bulbs. This is performed by removing the rear covering (rubber or plastic cap) of the headlight assembly from the rear. The bulbs are held in place by a spring clip that needs to be unlatched from the base/holder. Carefully remove the bulb taking care not to touch the glass envelope. The filaments would be readily visible and cut/breaks would be apparent. If determined that one of the filaments (high beam) is open, replace the bulb(s).

If the bulbs prove to be OK, you need to work yourself backwards tracing the wiring harness. After the bulb, check the 3 prong connector for any corrosion or scorching/burnt marks; clean as maybe required. Next to check would be the relay that provides the +12VDC and then the fuse.

I doubt if the dashboard or steering wheel components involve with headlights may be at fault.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Go through all your fuses, Dim lights run on a separate fuse.

SOURCE: high beam headlight does not work properly

it more then likey a lose wire or bear one. run the line down. i think that the high beams run on diff. fuses. you can try that!

had the same problem on my 92....check under the hood on the drivers side,towards the front,there is a "junction box" with all of the lighting wires connecting from the switches to the lights.My wires were all corroded inside,so I cleaned the ends and bought a new box from the local electronic supply store.The problem has not come back.
