headlights not working....
Hello members, i have tried every search i can think of and nothing is helping.
a few days ago my headlights stopped working. i know this because i was driving at night and all was well, i remember using my highbeams on a particular road. anyway the next morning (i leave for work around 6:15) i started the car aND put my foglights on (i did the foglight w\ parking lights mod AND disabled DRL's) and when i was geting ready to pul out flicked on D\L and nothing. Checked all fuses i could find and the bulbs are not burned out. Any help would be appreciated, before i take it to toyota. |

Check the bulbs first. It's not that likely that they both failed, but is worth a look.
Check the two H-LP fuses in the under hood fuse panel. Check the ECU-IG fuse in the under dash fuse panel.

ok i checked and it was one of the fuses under the hood. unfortunantly when i replaced it, the fuse blew again...
i think the next step is to rewire things to stock (Looks like someone was messing around underthere that wasn't me!) and se what happens any suggestions are welcome THX again |

The extremely difficult one to remove and put away. . Lol. If your standing in front of the car facing towards the rear, the left of the two you said to check.

That's the fuse for the right hand side (sitting in the car) headlight. The fuse feeds the black wire on the headlight directly, and then the green and blue wires are the switched grounds for high and low beam. Since you are popping the fuse, the short has to be between the fuse and the bulb.

Oh nuts you already checked. Would a beefier fuse solve this problem? CT? I'm genuinely curious |

NOOOOOOOO! Putting in a bigger fuse generally results in doing far more damage. Wires have a current rating and the fuse value chosen for a circuit generally is a function of the ampacity of the wiring and the maximum current draw of the device(s) on that circuit. Installing a larger fuse often results in exceeding the ampacity of the wiring, and if there is a direct short in the circuit, the now underrated wires will get extremely hot, possibly hot enough to melt their insulation and burn other things (or create more shorting points).

Agreed, i wouldn't think of using a larger fuse... and i did check to see if the bulbs are good, i can see both hi\low filaments, they are intact and the bulbs were less than a week old at time of origional post.
Thanks for the replys CT, but you were saying something about which wires to follow... if pictures will help i can have them on here tomorrow. |

Ok. So I am still battling this problem. The headlights come on now. But the driver side light is acting funny, both of the filaments are coming on and they are dim in comparison to the other one. Which works correctly. I don't know how it got to the state it's inn now. But at least I can drive at night. Any more ideas CT? Thanks again in advance

Thank you CT. unfortunatly that didn't fix it. And it's the left relay under the dash, because the middle one has five prongs while the other two have four. You are still very helpful. And I wish that fixed it, boo. I was so excited for that to work. What's next? (sigh)
