LED Fog lights issue

Bought some led fog lights to replace my halogen. They worked fine for a couple of days and then they just stop working. I put the old halogen fogs that were working fine, and those also stopped working. I checked the connector and i dont get 12v out of it. I found a schematic for a 2007 tundra and checked fuses and what i think was the relay. But it all seems fine
any help would be helpful thanks

 

Is the OEM connection still there? Is it corroded or damaged? I suspect your trouble starts right there.

Verify all four lights work right off the battery. Most of the higher power LED's out there are polarity sensitive and I'm sure you know that.

Yes, the relay can go bad but honestly they are pretty robust. If there is another in the fuse box just like it, swap them. Also look at the pins for tarnish and corrosion. Reseating them several times can freshen the contact surface. Clean with electrical contact cleaner, treat with dielectric grease. Same goes for the connections to the fog lights.

If all else fails, you need to test the continuity between the relay power out and the plugs at the fog lights.

Turned out to be the relay. Bought a few on Amazon and just replaced it and wouldn’t you know it lights came on. SMH ‍♂️

 

Curious is putting the old relay back in makes it not work anymore. I only say this because it’s pretty rare for a relay to fail but it can happen.

Good to know it’s fixed and working

 

I’m assuming the relay went bad
