2018 Tundra fog lights not coming on.

Is there a secret handshake to get the fog lights on? I have the factory LED headlights and LED fog lights. Tested the fog fuse and that was good, not sure how to test the relay. Truck has 2,000 miles on it and this morning was the first time I tried to use them. Any help would be much appreciated.

 

Take back, under warranty

 

They only come on when low beams are on. So be sure to check that their switched on as well as headlights, and it's dark enough for the headlights to be on if you're in auto on mode.

There are a few modifications you can make to change that but from the factory that's how they work.

 

Were your headlights on? If so, were they on high beams by chance? They won't come on without the headlight switch in the low beam position.

Yes, headlights on manual setting and low beams on. still no fogs. Dealers are 2.5 hours away.Not a fan of them working on my junk anyway.

 

Does anyone know how to test the relay? I have the tools but I am by no means an electrical wiz.

 

I'd try just replacing the fuse even if it looks good.
Also this is the relay try just pushing it in l, maybe its slightly out.

 

Just swapped out the fuse, no go. I looks like my relay setup is a little different than yours but I did make sure they were seated properly. Thank you.

 

It actually looks like you're missing the fog light relay unless the fuse box varies significantly from year to year

 

Well, that’s not cool.

 

Would anyone with a 2018 with fog lights mind sharing a pic of your fuse block ?

 

Did this ever get fixed? If so what was the issue. I have a 2018 CM and the fog lights worked when I bought the truck. They worked when I put new Rigid pods in and now all of a sudden they dont work.

 

I did get them working again, It ended up being a bent pin in the remote start harness. Good luck getting yours squared away.
