Thread: Headlight won't turn off - ideas ?

    I replaced one of the 2 headlight relays. Now I have both daytime running lights come on when I turn the headlight switch to "on" and both go off when I turn the headlight switch off. Both daytime running lights also go off if the ignition is turned off.

    But now I have no headlights period. And the blue high beam indiciator on the dash stays illumainated all the time regardless of what position the headlight switch is in. Both 15 A headlight fuses are good, but just to be sure I also replaced both with brand new fuses.

    Do you think I should replace the other headlight relay as well? I am a bit worried that there's a bigger problem, it seems odd that both headlight relays would fail at the same time, unless the failure of one relay then causes the other to fail for some reason? This entire situation is getting very aggrevating. Thanks for any advice guys.

    Well...just for the detail....which one? low beam or high beam? relays.jpg

    SInce those relays operate the ground side of the beams (rather than the hot side ) there are a lot of bizarre consequences experienced and predictaBILITY is, well, quite random....so lack of details makes it worse...

    UPDATE: Replaced both headlight relays and the wand/headlight switch. All brand new parts.

    Same problem. Headlight on passenger side stays on regardless of switch position and driver's headlight blows the 15 A fuse. Also no high beam.

    I really hate these electrcial gremlins. Anyone have any ideas ?
