    Turn, reverse and brake work just no running lights hence no tailights sorry if it wasn't clear I was pretty pissed and cold last night.

    Yes just no tail.

    I just go this rig home lol.
    Yeah just no tail/running light whatever you want to call it.

    No power to the taillight wire that is my issue here and I can't seem to figure out what the hell happened.

    OK so if the trailer harness is working and it’s on the same fuses as the tail lights, I think that narrows it down to something going on at the rear of the truck. Am I wrong? My next thought would be, does the trailer harness run all the way up to the fuse box or does it splice into the tail light wires at some point on its way to the rear of the truck.

    I'm almost a full pot in, almost time to temper that a bloody Mary. I could be totally wrong but I think the headlight switch is the culprit. If brakes and turns work but no tails and now no fogs, all of that is contained in this one multi-function switch. s-l300.jpg

    I'm sick of this snow it's been horrible this year and the shit they put on the roads does not help. And being negative temps all night doesn't help either.

    I was thinking the same but he said it works through the trailer harness. That’s what’s throwing me off.

    Try giving the current headlight switch some reasonable contortions and see if any functions return.

    I initially disregarded the switch, being that his truck is so new. But he’s got a lot of miles on it so you guys may be right.

    True, but we have to be somewhat creative too.

    Very true. I'm just going off of past experiences. I recently changed one out on a Chevy Malibu where it only killed the left front turn signal and one on a Dodge Dakota where all of the light functions are in the stalk like our trucks. On the Dakota when the column clicked the left turn off, the left brake light wouldn't work. All fuses were good in both. Too bad we all weren't closer, today would be a good day to contemplate this over bloodys and beers:D

    Everything else works besides the tails and the fogs. But my trail light plug still works. Which is whagbus confusing me here.
    But it's worth a shot to try out

    183k now lol. Kinda shitty if little things start falling apart now.

    It's been a good truck so far. Only blown out an axle seal. One wheel bearing. Radiator had to be changed. Alternator went out. Blower motor went out once. Main seal is dripping a little bit and now the tailights went out lol.

    I'm gonna find the part number and order the the multifunction switch for my truck and we what happens.
    Well I'm Minneapolis lol you're only the state next door and I don't think 10 am is to early to start drinking lol.

    I’d be in! I had strange problems with my Chevy all related to the ignition switch. It would go into limp mode at random. I would start the truck and it would be in limp mode. I would shut it off and try again, while delicately trying to position the key in such away that would finally work. All this while trying not to take a hammer to it! Once it even just randomly applied the brakes while I was driving, to the point where it wouldn’t even move. I had to shut it off in the middle of the street put it in park and restart to get the brakes to let go. Changed the ignition switch, and all was well. It just didn’t make sense to me because with older cars, this would never be a symptom. I had to change my thinking.

    I would love to have some beers and try to figure this one out.

    I had an issue about a month ago where my steering column was locked and my key wouldn't unlock it. I figured out my key was a little bent lol. But I got it going to get myself home lol.

    It’s strange to see you have so many issues but you do have a lot of miles. I imagine most of those are highway. You definitely use that truck!

    Was that when you tried to lock the tailgate with the key?

    Don’t know if this has been covered, but check the ground points, they may be a loose ground somewhere , these trucks have ground points everywhere around the body and engine compartment.

    If the tail lights work on the trailer circuit, I doubt it's the multi-function switch, but that could possibly be a reason why the fogs don't work. The truck tail lights and the trailer tail lights should should be on separate fuses. Remove the tail lights, find the tail light wire, grab a test light or volt meter, and start following and testing that wire working towards the front of the truck.

    I believe it got bent from.locking and unlocking the tailgate so many times.
    I don't believe it could be that since everything else works but I'll give it a shot.

    I know there's no power to the wire from where the tailights hookup.
    I just have to find the correct wire under there and trace it after I unthaw my truck out. It's pretty packed with snow right now.

    That's exactly my thinking as well. If there's no power to that wire, then follow it back.

    Little update,
    My fog lights will turn on but then shut off after a couple seconds. This leads me to believe there is a ground issue somewhere.
    I ordered the multifunction switch so hopefully that is the issue with my taillights I'll follow the wire back this weekend to see if it's damaged somewhere I believe it might be. and the issue with the fogs is just a bad ground.

    I’ve seen relays do weird shit like that before.

    Same boat here. Fuses are all good, checked both visually and with with a voltmeter. Fuses are getting voltage to them, but no power back to the tail lights, fogs, license plate lights. I was hoping to pull some power off the trailer plug as a temp fix, but no power there either. Just bought my 08 (4th Tundra I’ve owned tho), and previous owner threw on some LED tails and different headlight housing. Slowly trying to bring it back to stock so I can find the gremlin. It’s somewhere between the fuse and lights. Replacing the relay might be my next thing to try so I can rule it out. Is it just the fog relay? I got a Haynes manual in the mail so I need to go chase the system down still. Just been trying the obvious first.

    I swapped the fog light relay with a different relay and it didn't make a difference. I'm gonna throw the truck in the shop Sunday and see if I can figure it out.

    Lost track after #1.
    You check the fuses under the dash on the driver's side?
