Bad Headlight Fault… Need help.



  • When I picked up the MX-3 it had a headlight bulb knackered so I replaced it.
    However now, when I switch to main beam, the lights drop down to side- lights instead of up to mains.
    Flashing main beam works fine.
    Also, if I am driving along at night, I can lose my dipped lights down to sides for about 30 seconds then they come back.

    The latter problem sounds like some kinda wiring defect, but what could the first problem be and could they be related?????

    Help much appreciated.



  • Hi there,

    Had a fault very much like this on my calibra, turned out to be the Main beam selector switch on the steering column was fooked.

    Could be worth checking the connectors to the main beam selector switch and using a multimeter check the continuity through the switch itself.

    Question, was the fault present before you changed the headlight bulb and does the fault occur on both sides?

  • No idea if the fault was there before.
    It happens to both sides so the switch could be a good bet.
    Is there a relay involved as well???



  • There is a relay, looking at the circuit diagrams it swiches on both normal lights and main beam at the same time (it is second from right in the main relay box) so that would explain the lights dropping down to side only.

    This Relay is before the switch in the circuit so it could be the problem and certainly easyer to check than the main beam switch.

    Added, when you find the fault, let me know what it was, this ones got me intrested now.

    I certainly suspected the relay for the reasons Mutts details above.
    Mine is a '93 1.6 4-cyl.
    Could you let me know how much, where etc???
    Thanks



  • im all the way in nottingham mate.

    Relay will cost you nothing.

    jsut pay for postage.



  • Many thanks.
    Bit far to drive for a relay :lol:

    Bit of trust reqd then.
    Without knowing how much it will cost, would you be willing to send it down and I'll send you the postage by return?
    Or you could come up with another plan ??

    Cheers,
    Phil
