Is there a fuse for trailer lights

I have a 2000 2.4 and I hooked my trailer up and the running lights lit up when I turn the lights on but the brake and turn signals won't work?

 

Yes there is a fuse (at least in the 2nd gens) but that doesn't sound like the problem. I wire a lot of trailers and I've had this happen before and it's usually the result of a poor ground or the wires going to the lights having a loose connection somewhere. First try wiggling the plug and making sure its getting full contact and then if that doesn't work examine the wires. Also, some lights have a separate bulb for blinkers that might be blown but if the brake lights are the same as running and not getting brighter try what I said above.

 

If it has the tow package, then there is a relay on the back wall behind seat, 3" square box w/wiring harness running into it from bottom. There is inline fuses there. Other than that there may be a fuse under the hood also, i dont remember.

 

You almost definitely have a loose wire somewhere, most likely a ground. If you have a 2.4 there's no tow package and you have some kind of aftermarket trailer light setup. Does your plug on the truck say Uhaul on it?

 

Nope it says Toyota on it I looked checked everything to my ability at a shop now ill let u know what it was. Thanks for the tips

 

If it has factory toyota trailer light harness there is a relay box somewhere. It has those fuses to protect the rest of the lighting system. Mine use to blow fuses backing boat into water until i switched to sealed LED units.

 

Ended up being a bad converter. Pep boys had a exact plug in replacement.

 

Where was it located on your truck? I said relay but it is a converter. Was just wondering if they mount them in different places.
