well today my 4runner's signals stopped working today, checked the fuse it was blown, so i had some spares in my glove box and replaced it 3 times, as soon as i turn the signal on either way the fuse blows instantly, im not an electrical genious so i was wondering if anybody else knew?
thanks

 

Has there ever been an aftermarket trailer light kit installed? Most likely culprit.

 

not that i know of, i couldnt find any trailer plugs and theres not a reciever

 

Now will be a good time to learn to be an electrical genius

You have shorted wire someplace

I would check the back harness first

 

Have a look inside your rear bumper for any wires hanging out of the main loom leading to the tailgate assembly. You might have to pull of the reusable plastic "cowl" thingy... and maybe strip some electrical tape off. I had a short in a factory-installed trailer plug... not the plugs themselves, but one short section of wire somehow rubbed it's plastic sheath off and started to rust.

The best part? Mine only grounded out when it hit the frame... every 3rd or 4th bump would touch the two, then the next bump would separate them again and it would all be fine. What a b**ch.

The signal lights are easy to take off the truck, I would pull all 4 corners and have a look at the bulbs and local wiring. Good luck!

 

Ok well thats something to start with

 

have you checked your warning lights switch? the power for the signal switch runs thru there and it mat be shorted. my switch got stuck all the way in and shorted itself out. i would check that before tearing into you wiring.

 

Yea good idea, i checked the hazards and they work so i know the bulbs are fine
