    Greetings, This is my first post! I ran across this forum searching for fog light fixes for my non-functioning fogs on my 03 Tundra SR5 Access Cab. Last year I installed ebay LED's in both the headlights and fogs. They didn't work very well and eventually the fogs stopped working. I later switched them back to the OEM bulbs but still nothing. Two weeks ago I nailed a deer at 5:30 am on my way to work and never saw it coming. I've repaired the damage but want the fogs to work again so I can see these critters better! My Haynes manual isn't much help but I bench tested the relay and it works. The 15a fuse is good but I have no power to the fuse. Bulbs are brand new. Where do I need to go from there?

    Welcome from CO! Did you try bypassing the switch on the stalk using a universal type switch temporarily for troubleshooting?

    Not sure on a 2003, but on the newer models there's always power, the stalk switch just completes the grounding process if memory serves me correctly.

    I was going to recommend the same. Also you could run power directly to the battery temporarily to rule out a problem with the lights themselves. Usually a 9v batter will power up smaller LED lights too.

    Where can I get a wiring diagram for an 03 w/DRL's & fog switch on the turn signal stalk? My Haynes Manual doesn't have the right one.

    Thanks for all the replies! Had a few minutes last night to tinker with it but still not fixed. I'm leaning towards the stalk mounted switch based on the schematics. I may go ahead and pull it out and bench test it asap.

    az chip, where did you get that electrical schematic? I need the whole set if they come that way! Thanks again!
