Problem with right Crossing signal

Good morning I would like to know why in my tundra SR5 Crew max 2025 my right turn signal does not turn on, change the entire unit and still continue the problem, But I have my Tundra Vent Lights w/ DRL And this one does work well when I make the right turn signal so I think it shouldn't be the wiring since I connected it to the same cable. Has anyone gone through the same thing?

 

Turn Signal?

 

Yes the turn signal has problems I don't know if it's because of a fuse or some wiring

 

It’s a brand new truck. Take it to the dealership.

 

Noi buy this in a Car Auction and the title is rebuild so the warranty no longer has it

 

Did you install the vent lights?

Were turn signals working correctly before the installation of the vent lights?

 

When I bought it, the bulb was broken, so I bought a new one, installed it and the turn signal did not work As I had bought the Vent Lights I installed them at the same connection as the light and these are working so I do not know what may be happening

 

Do you have a voltmeter?

 

Yes i have

 

I guess the next question would be have tried to use it to track down the problem?

 

The dick didn't because I thought it could be some fuse but I don't know which fuse controls the lights or the turn signals

 

It should say on the inside of the fuse box lid.
It's basically a map depicting what each fuse does.

 

Ok I have 3 boxes As I understand 2 in the engine area and 1 internal, right? I checked each of them but I can't identify the fuse I will send the 3 photos to see if you can help me please

 

The vertical image is of the cabin



The picture with the L-shaped cap is on the driver's side



And the other one is from the passenger side

 

It should be the one under the hood but I cant be certain.
Does the Lid not tell you what each is for?
If not you should still be able to check the fuses even without the fuse map.
It's a simple matter to pull each fuse and inspect them visually.
Or use your voltmeter.
It'll be readily apparent either way.

 

And of course if you find and replace the offending fuse and it blows again soon after you have a short somewhere.
But finding the short obviously becomes much easier when you know where to look.
Just follow the wire testing continuity as you go and you'll find the location.
In most cases it's readily apparent when you spot it.

 

If the problem is just the right turn signal not working and the left does work properly, it isn't the fuse.

 

I think it's the new bulb I bought that came with the turn signal damaged

 

Are turn signals canbus? If so then you may not be able to just attach another light bulb load to the bus.

 

How do I know if it's canbus? I think it should have nothing to do with why the light didn't work before installing the vents lights That is, it should have worked together with the left light without any problems

 

The lights in gen 3 are canbus, including the turn signals. If they weren’t working before, the harness or circuit was probably damaged in whatever wreck it was in that produced the salvaged title, and was never properly fixed.
