Trailer Lights ....

Left/Right turn signals work
Brake Lights work

Running lights ...Do NOT work ?

All connections seem to be tight ...I am no electrician though

 

Checking for a good ground is usually the place to start.

 

Check the ground first and if not then see if there is a chaffed wire touching metal. Are u sure its the trailer try hooking it up to another vehicle. This stuff sux I have a landscape business and do this weekly ha ha so frustrating!!!!

 

I had a similar thing. It was a fuse in the truck.

 

You need one of these! http://www.sears.com/tekton-12-v-continuity-tester/p-SPM2092196603P These things are worth their weight in gold when it comes to wiring and fuse troubleshooting.

 

also look at the bulbs. If you have a double filament, one might be burned out. I just had this problem today.

 

Is it a Dodge? I have a similar problem. It's my left turn signals that don't work. It's not trailer lights... but the truck light connections. I have 2 plug ins.... both fail on the left turn signals. I just have to take the time to have the garage wire me up a new left turn signal wire. My garage guy says it probably is a problem with the fuse box. I don't see that as all else works.

 

Thanks for the suggestions still gotta check it out . And its a Tundra David

I don't know if Tundras have the same style connection or not, but my Toyota had a wiring box for trailer hookups that went out.

 

It's the dark brown wire. Running lights are always the first to corrode. Check the back of your plug. Wouldn't be surprised if the wire is busted or nearly broke. I'll see if I can track down a diagram.

Okay I am definitely reading Tundras use a trailer light converter box just like the smaller trucks. They do go out and cost about 30.00 or so dollars. If yours is bad, you can simply check with a meter to find out, buy one with the LED lights on it so you'll never have to guess again as to whether or not it is working.

The running light circuit was what went out on mine. It is simple to change.

 

I got one like that. It blinks does that mean its a fuse in the truck?

What blinks? I am working from memory here, but I seem to recall the turn signal LEDs blink with the trailer lights, the running light should be on steady. If the running light LED is blinking, that would indicate a loose connection to the box or a failed circuit component inside. Maybe someone else with a rice burner can look at theirs and answer this? I can't remember for sure.

 

The adapter piece on my truck that the prongs plug in has LED indicator lights it blinks on the brown wire which is the running light wire. I just can't figure out that means or how to correct the problem

Check out this short video. This should help you get it fixed right up. Hopefully you have the adapter that plugs into the existing vehicle wiring blocks. If not he explains what to do.

Gonna watch that a little later ..just pulled the adapter out and tested the prongs I don't have any power running to the one labeled tail lamp ...this sucks. They just worked in March?

Also checked every single fuse. None blown.
