So took my car in for paint, got it back and now the tail/dash/licesnse plate lights wont come on. Let me explain The fuse blew, so I put in anouther fuse and it blew instantly, so typical me i was like fuck it and put in anouther one, It worked for around a minute. then blew. SO i have traced the ENTIRE wiring harness and not found a single short to ground etc.... their is no relays in the tailight circuit.

So my question is, *It's not a short to ground in the harness* what COULD cause the fuse to keep on instantley blowing ?

a bad bulb...take them out and look at them...

Have you just visually inspected the harness, or did you actually use a multimeter and see if there is a short?

Yea bulbs are fine. Umm visually inspected the harness and in did check with a voltmeter. Thinking it could possibly be the switch that turn on the head lights and all,. Because its one of the twistie kinds and on the first click its the dash lights ( which blows the fuse ) 2nd click it turns on the headlights and 3rd click the tail lights. so could pobbily be in their ? i hope

Pull the fuse, take out the bulb, and use the multimeter to check for resistance to ground at the bulb connection. Then track back from there, unplugging harnesses as you go to remove them from the equation. If there is a connector that disconnects that switch, unplug it and test the switch itself for shorts. That's the most direct way to go if you suspect the switch is bad, then you can either rule it out or tell that it's the culprit. You should do all of this without any power to the circuit, because you already know you have a short to ground so resistance is the most informative thing to check.

yea been trying keep hoping I can see the OL on the resistance check but iono im comming up real short on this one.
Its a 1992 toyota pickup 2wd 22re motor. Looked up the wiring diagrams and all and shit just isnt making a whole lot of since other than makko sliced the power wire to both license plate lights which is in the same circuit as the tail lights

well since they cut the license plate lightes...have they been reconnected??

if so...disconnect them and see if it blows the fuse...

yea okay so ive done a ton of work to it, And basically the problem should of been a 98% chance of a short to ground, but turns out it was the switch on my steering wheel, go figuere,,. THanks for the help and ideas .

dorydorydriftin

WAHHHHHHHHHHHHHH .... it's still not working ! lol. Okay heres the problem, narrowed it down to the fuse box under the dash. The problem im having is that from EVERYTHING i see, haynes manual, alldata.com etc... is that their is a tailight relay switch. But at autozone, napa, advanced < their is no such thing as the relay. How do i go about replacing a relay that doesnt exist in a way ??

Look it up on a site with Honda parts?
