Question about 2003 Mitsubishi Montero Sport

1 Answer

Head lights went off while driving.

My wife was driving home (after dark) and the headlights went off. She pulled over and tried the switch and still no lights. All other lights work but the headlights.

    It turned out to be the altinator. The altinator caused the voltage regulator to go bad and burned both headlights out.



    I appreciate your trying.

    Both head lights went out at once. Fuses are good. Flood and running lights work. Cant seem to find the problem with the headlights and why they both would go out at the same time.

There is a Relay for the Headlights and Fuses also. Check under the Hood in the Fuse Relay Box and the Fuse Panel on the Inside. They should be Marked as HL or RHL and LHL. Also just check Really Close for Blown Fuses. Let me know if you need any Further Help. Please Rate my Response, I need all the Help I can get! Thanks!

Headlights stopped working


I think it's either the headlight switch or the dimmer switch. I would get a manual on your car. Head light switch you have to take apart the colum to replace it.

The switch is bad >
Each headlamp is individually fused so that battery voltage is applied to the individual lamps at all times through circuit 1640 for the LH headlamps and through circuit 1740 for the RH headlamps. When the headlamp switch is in HEAD, the ground is applied directly to headlamp switch through circuit 1750. When the headlamp switch is placed in LOW, ground is applied to the low beam headlamps through circuit 1201. When the headlamp switch is placed in HIGH, ground is applied to the high beam lamps and to the high beam indicator through circuit 1200. The high beam indicator is fused so that battery voltage is applied at all times through circuit 640.

The box you hear the click in is the daytime running lights control module .
Do you know how to do electrical testing using a DVOM- digital volt ohm meter or a test light ?

Flickering headlights


This can be caused by a bad fuse, or a fuse with corroded or poor contacts, or a faulty headlight switch, or a problem with your wiring. Start with the fuse, then try turning the headlights on and off a few times to see if that helps. Otherwise, into the shop ...

Headlights don't work why?


Test the headlight switch as follows.
  • Move your car to a dark area, such as waiting until night or moving to a dark garage, to test your headlight switch.
  • 2Turn on your car, so you can see your dashboard lights. Note whether some of your dashboard lights fail to illuminate.


    • 3
  • Turn on your car's headlights. Note whether your car's headlights illuminate.
  • 4Press the high beam lever to activate your high beams. Note whether your high beams activate.
  • 5Put your car in "Park." Move to the back of the car. Note whether your parking lights are illuminated.
  • 6View any remaining driving lights, such as lights above the license plate. Note whether these lights come on.
    If more than one set of lights does not activate when you turn on the lights, you may need to replace your headlight switch. If only one set of lights does not turn on, try replacing the lightbulbs in that set and then retesting your car. If the lights still do not illuminate, you may need to replace your headlight switch.

    What started this mess? tailights, fog lights, brake lights....


    The relay has nothing to do with the tail lights, but replacing the switch sounds like a good idea. There's a nut holding it in place, see http://www.skandix.de/en/spare-parts/electrics/switches/switch-headlight/1027524/ to get an idea of the construction. And the price. This is not worth fiddling about unreliable workarounds...
    In addition, if fuses 15 and/or 16 burn frequently there might be a problem with the tail light cabling.

    Good luck
