Hazards Not Working

Hello all! I have a 2021 Tundra TRD Pro. Recently my hazards or flashers stopped working but my turn signals work without issue. When I press in the hazards, I don't hear any clicking at all.

I've located both fuse boxes under the hood but I'm unable to locate any fuse that is labeled as hazard or flasher. I also don't blatantly see any hazard relay labeled.

Anybody have experience with this?

Thank you!

 

Welcome to the forum from OKC!
There is a second fuse box with mini or micro fuses up above the parking brake. Way up under the dash you will see a black cover about 2"x4.5" it snaps on/off. Fuse diagram in manual.

 

Extremely helpful, thank you. I was able to locate and inspect the 15A hazard fuse but that's not the issue. Anybody know if there's a separate relay that possibly needs to be replaced? Again, when I push in the hazard button, there's no audible sound nor clicking.

Thanks!

 

The relays on these are built into the instrument cluster. Not exactly great. Have you had a trailer plugged in with bad wiring? Have you checked all of your bulbs? Did anybody put in led bulbs?

 

Check your brake light and trailer light plug fuses too.

 

Could be a bad switch if you don't hear any click when you activate the hazards. That's a pretty low use item though, so that might be a long shot

 

Good call! Not low use for everyone, I can see someone in construction or pilot car possibly using frequently.

 

Welcome to the forum

You could try connecting pins 1 and 5 in the J127 connector and make sure it isn't the HAZ switch.
J127 is the plug for your climate control

 

Thank you so much for the suggestion; I'm quite new and oblivious to what you're referring to. Can you please be more specific as to where this is located?

 

Thank you! I've tried all brake and trailer lights, haven't had any issues. No LED bulbs nor any bulbs replaced recently.

 

Thoughts or input as to how to access or test? I was just informed that water may have splashed up against the dash but quickly dried out. All other lights, climate control, seat heaters, etc. are working without any issues. Again, turn signals are all working without issue.

 

You'll need to pull your climate control panel under the radio..
Remove the climate control panel, and it just pulls out.
Video starts where you need it.
I usually pull the bottom panel out first, it pulls out as well.

Use plastic tools to pry it out.

 

Pretty sure I had this issue and it seems like it was a trailer light plug or brake light fuse. Did you check the trailer plug fuse? I can tell you whatever it was, it was in the small fuse box. Might be able to pull and check all of them since so easy.

 

I checked the brake light fuse, in good shape. Where is the trailer light fuse, I don’t see that here? Photo included of my interior fuse panel.

 

Honestly, my memory sucks and it has been like 2 yrs. Maybe just çheçk them all?? Not hard. I think I read that they tie into ignition so maybe ign fuse. Sorry, bad memory and not a big life event. Might be under hood.
