Daytime running lights

My Tacoma drl aren’t working properly.
When only drl are on driver side is normal and other side is very dim.
When fog and drl are on they are both fine.
When all lights are on the driver side is dim and other side is normal.
Anyone else had this problem? Any advice would be great.

 

Electrical gremlins... take to dealer if issue is easily repeatable. Could be anything from an internal switch short to rodents eating wires.

 

That’s all controlled through the BCM. Hopefully you’re still under warranty

 

Got an image?

When headlights are on, both DRLs should dim.

 

Don’t have pic yet. But one is bright and other dim.

 

Mods?

 

My advice. Warranty!

 

I'm not saying the "T" word yet.........

 

No mods to lights. Just cosmetic stuff.
