Chevrolet Silverado Problem , Trailer Running Lights Would Not Work - FIXED

[@chrispaulus4491]

Thank you for the help! In my case, every fuse tested as they should. However, the 15 amp fuse was physically the wrong size. Once we replaced it, the running lights worked! 😊

[@chuckclark7444]

Originally thought it was my trailer wiring. They were getting worn and brittle. Had a neighbor plug his truck into my trailer and everything worked. So I knew it was my truck was the problem. Came upon your KZbin video and that was it. 15 amp fuse. If it keeps blowing maybe my trailer wiring is a problem LOL. But you got me going in the right direction. Thank you

[@DeliB4]

Thank you! 10 years and your still helping people! After an hour of messing around that was it. A fuse.... lol

[@Ruth11]

I screwed with the trailer and the connection and had just made an appointment at a dealer to trace the problem in the truck when I thought I'd check U Tube. My truck was a bit newer than yours, so different panel configuration, but I found the relevant fuse and sure enough, it was blown. $1 fix. Thanks.

[@marshallcollins8634]

I didn't need this video but I know it would help anyone who is having trailer lt issues. Your a lucky guy to have a dad that 1)is smart and2) willing to help you. Please don't take that for granted. It is important to have a GOOD Father in a child's life, take advantage of that and always appreciate him. Glad to see he is rubbing off on you ,by posting this video.👍🏻👍🏻

[@masterplumber8610]

After a new trailer wire plug about 4 hours of scratching my head and this video my trailer lights work. THANK YOU!

[@peesmkr]

This was a very timely video. My company truck was having trouble with this same problem with our trailer lights and the next day while I was filling up with gas I checked this fuse. The dash fuse box on the drivers side has extra fuses and I replaced it and it worked ! Thank You !!!

[@GoldenPepperFilms]

I took my trailer to a boat shop; they looked at it but concluded that they couldn't fix it as they don't do that kind of work. So after watching your video I replaced the fuse, and then I replaced some wiring that got pinched and "Poof" it works great. THANK YOU!!

[@ups0913]

Does everyone with a chevy have this problem. I couldn't figure it out until I seen your video. The fuse is in a different spot in the fuse box on my 2000 chevy. But your video saved me so much time. Thank you, good sir.

[@brycegroening13]

MartinSeamusMcfly yes

[@brycegroening13]

Very helpful!

[@colonelklink510]

There's a KZbin for EVERYTHING! Thanks man. My trailer cord got severed when it got pinched on the ball last week and shorted everything out. After replacing the cord, I still did not have all my lights. I found a couple fuses in the panel on the side of the dash that were marked TRLR and one of them was blown. When I picked up my new trailer today, I had the same symptom you had. Turn and brake light worked fine but no marker lights. It's dark out now but I would bet a dollar that the fuse under the hood is blown and it will be a simple fix. THANK YOU!!!

[@timschuchard9626]

thank you for this comment

[@juanramirez5817]

I needed to do a delivery in the middle of the freezing cold night, I was striking out all day with just about everything. When I was ready to leave I noticed my lights didn’t work. I was like just what I needed and my dad suggested it was a fuse, I said no but looked either way on KZbin and bam found this and it was my exact issue and the exact fix. Thank you sir

[@jacobbeck1421]

Me and my Brother want to thank you, even though he has a 2021 this was extremely helpful to us, he checked for this fuse in the fuse box and this was the problem still! Replaced fuse and now the trailer is ready to rock! Thank you again for this!

[@KenWiggers]

Thanks, worked for me -- solved my problem with 5th wheel trailer lights not working. Replaced the 15 amp fuse on my 2004 Chev Silverado 3/4 ton diesel. A conductive wire connected to the "pins" at 11:00 a.m. and 1:00 p.m. on the trailer plug in turned the running lights on (indicating a blown fuse in the truck) -- the trailer has its own battery. Your posting showed me which fuse to pull and replace.

[@mikewendyssnoozyadventures5395]

If I could I would hug you!!! I was less then 12 hours from a camping trip and discovered my trailer position lights were not working. I also have a Silverado, found the fuse, replaced it and LIGHTS!! I figured it was a fuse but would never have found it so quick if not for your video....THANK YOU for making a video you probably thought no one would watch

[@chuben8160]

I appreciate this video of yours, my father was struggling with his 99 silverado he hauls a trailer every day and had to use the hazards at night but not anymore since today. Thank you sir👍

[@raven09r1]

Thanks a billion, if you’re still checking up on this. Worked for my 2021 as well

[@Garnasus]

I wasted so much time today tearing apart lights and checking other things..I never would of thought the running lights had their own fuse. Thanks!!

[@L1v3FrE3]

Your video is still helping folks out. I knew it was probably a fuse but you made it quick and easy for me to find the correct one. Had the exact same problem. Thank you.

[@dougcollman3815]

Had a short on one of my sidelights - hot wiring to a sidelight when I connected the nonworking running lights. So I cut the wire to the sidelight, found the fuse you pointed out and it was blown :). Replaced it with one of the spare fuses in the under hood box, and, TAH DAH! Thank you so very much for uploading your video! Hope you're still around to get all these kudos...

[@Jim1468]

I recently bought a travel trailer but running lights were not working. I worked all day yesterday trying to figure it out, to no avail but your video got me going in no time. Thank you thank you thank you!

[@thomaslawrence3232]

I am so thankful people like you upload these videos.

[@PENNYATCAMPCOLLINS]

I was just starting to go down a rabbit hole with my 2022 Silverado then I played your video. It was kind of strange how all the trailer fuses were grouped together and this one was out in left field. I usually start with running the test light down all the fuses but of course this time I didn’t 😂. Great video, you saved my sunny afternoon chasing ghosts !!!

[@stevep1062]

Thank you so much for posting this. This was my exact problem. I spent about an hour with a multimeter trying to track down the problem and finally did a search for my problem and found this video. Thanks again.

[@scottphillips181]

Thank you! Spent close to 8 hours trying to figure out why I had no power for running lights. This has to be for safety reasons so you don’t loose all your running lights when a fuse blows

[@jessemiles2570]

Bro you saved me a lot of headache. Watching your video made me check mine because I had the exact same issues no running lights just brakes and blinkers. And surely enough my TRL PRK fuse was blown. Thank you. I also have a Chevy Silverado it’s a 00 2500 and it has a trailer brake hook up. Well worth the time watching.

[@lordapprentice450]

I just watched your video and went to the fuse and it was good. I started polking around and opened the relay 4 the parking lights checked it with a multimeter across the resistor and it clicked. Pulled the relay plate away from the transformer and let it reconnect my rear taillights work again. Hope it's helpful to y'all and saves you some cash

[@sknox102908]

Fixed my problem in 2 seconds thanks to this video. I forgot i was also messing with a power inverter and luckily had a spare fuse in the inside box. Much appreciated man👍

[@mario7mag]

Thank you so much for taking the time to upload a video like this. You really save my butt in a situation I was having. exact same issue, I needed to use the trailer ASAP and I couldn't figure out where that fuse was at but thanks to this video and your help I got to take care of. Blessings brother!

[@mikethomason338]

Fixed problem on my 2000 Silverado .. Was a 15 amp fuse but was located lower in the fuse box labeled TRL BU .. Was driving me Nuts! .. Thanks for the fix ...

[@tylersmith7054]

My dumb self had the test light out and took the junction box on trailer and plug on truck apart. A fuse.... A damn fuse. Thanks for saving my evening. My mood was declining quickly!

[@b.mcdaniel8979]

Thanks! Same issue fixed! I knew about the fuses in the cab fuse box, but did not know about the "trailer lights" fuse under the hood! I found a blown 15 amp fuse just like your video said it would be! Problem fixed! Awesome, thanks man!

[@russosborne3574]

Eureka!! Thanks SO much,been struggling for two months,why do my hazards and turn work but no running lights.you ARE the man!

[@codyowen9058]

Very very helpful, I have the exact same problem with my trailer, after buying two sets of lights, a new 7 blade to 4 pin adapter, and having the same issue, checked the fuses in the cab drivers side (2012 Silverado) all were good. Totally forgot about the fuse box under the hood, will be checking that fuse box soon.

[@markintx2628]

Great video I am on a trip 400 miles from home when I left my running lights weren't working. Watched your video problem solved thanks man Mark

[@drose4990]

Had this running light problem last night, my fuse box is played out a little differently but your video should me what to look for. Problem fixed, thanks for posting the video.

[@jamesmitchell780]

dude you are a genius!! just saved me $70 per hr to have some mechanic tell me i need all new wire harness!!! I love KZbin 🍻

[@shariecelanette]

James Mitchell yes, he saved me more hours,,, now that I know which fuse, I can find the problem in the trailer !!

[@lay1back]

Also, there is a relay that can keep taillights from working. It’s the large relay on the left. You can swap it out with the on to the right to check.

[@samloving8314]

Man thank you for this video. I was under the gun and had to fix the running lights before we go on vacation. I only know a few things about how to fix problems. After fixing a problem I knew I had I knew I was going to need some help to go from there. Your video sent me directly I mean directly to my problem. Bam Baby!!!! I went from uh oh I don't think I'm going to get this fixed today to Hero!!!

[@montezumameddie]

Thank you sir once again a youtube search and a more experienced soul saved me a lot of time and effort. I was looking in the right place but trailer park wasn't the words I was looking for in the fuse box. Problem solved.

[@barbiegalli]

Great video helped us in the middle of a road trip from getting a ticket or in an accident. Thanks so much!

[@jamesmcdaniel38340]

Thanks A Lot Buddy! I was fixing to run a jumper wire cause I had power all the way back to the harness tee's off and then lost it...looked at fuses on inside truck but not under the hood. After watching this went and looked and my GMC Sierra 2003 is exactly like yours and sure as the world it was blown! Not sure why but it was! Thanks buddy! James

[@etgrider77]

Wonderful video. Saved us a 4hr trip to return a brand new trailer.

[@gerardolugo7697]

Thank you! Not the problem on the trailer hook up, but on regular tail light running lights were doing the same. I didn't know the fuse would be under the hood or how it would be labeled.

[@williamwalls4857]

Brother thank you!!! was killing myself trying to figure out my issue! Couldn't have done it without you!

[@HarwantPannu]

Thanks for sharing the information. My 2010 GMC Sierra fuse box looked different. But your video gave me the idea on what to look for. It helped to fix the issue in about 15 minutes, something that I was putting off for months.

[@emilykennedy9603]

this video saved my life man. thanks for being so simple and straightforward

[@kevinrhodes3208]

DUDE THANK YOU!!!! There was wiring to a salt spreader on the back of my truck i didnt even know about, it was tucked up under the bedliner.

[@richmatoushek8340]

All I can say is Thank You. There was no fuse in that spot and lights working now thanks for the post spent a couple hours checking wiring.

[@Jshab121]

I have a Silverado. I tow a horse trailer. The directionals and brakes work but the running lights do not so I cannot haul after 5. Thank you ill give this fuse issue a try! Thanks for sharing

[@taylorh5287]

Thanks could not figure out why my trailer running lights would not work on my 2006 gmc yukon xl . This was it!

[@mattsrepair10]

Good share! Had me scratching my head and checking plugs and wiring til I found your vid! Thanks!

[@danakennard7727]

Thank you so much! Had the same problem on my 2005 Chevy Suburban and could not figure it out for the life of me!

[@brandonyeager4217]

$hit!!!! Mine hasn't worked for a long time!!! Just seen this video cause I searched and you're right!!!! That dang fuse was blowed on mine!!!!! Now all my running lights work on my trailer!!!! Thanks man!!!!!

[@racenascar]

Thank you for your post! my owners manual stated that my secondary fuse box was located under the primary fuse box under the dash in the cabin to the left of my stearing column. I couldn't find it! After watching your vid I went out to my truck ('06 silveradao) and not only located the fuse box under the hood but had the fuse replaced in seconds! problem fixed - thanks!

[@killeenyarda]

No word's to describe my gratitude brotha, I was totally stumped til I saw this.. THANKS so Much..I owe you a 24 pack🙏🙏😁👍

[@pamwhitney3425]

Awesome! I also, did not know about the trailer lights fuse. I found a blown 10 amp fuse. Thank you, you probably saved me $75 at the chevy place.

[@bilytaylor253]

This pointed out the only place I didn't yet check. Ya saved me a lot of hassle, thanks and God bless you.

[@danasampson818]

Thanks! My problem was the fuse also. I almost spent money on a new plug receptacle. It would have been nice if the owner’s manual described all those fuses.

[@russellmeszler4432]

This just helped me out - thanks! I did not realize there were trailer fuses.

[@SumLozerUNvrHeardOf]

You are a life saver! I was out with my dad trying to see what was the electrical problem with our trailer! Turns out that the TRL PRK fuse was shot and was of 20a, not 15a. Replaced the fuse and BAM! we took off for our vacation shortly after. You are awesome!

[@mrbojangles9841]

Your dad must be a sweet man for taking you on vacation.

[@Vgk36]

Hell yeah!! Same exact problem!!! Related to a 5ty wheels plug shorting the fuse out. Thanks!!!!!

[@BADBAMA323]

Thanks man. After 1 year of not being able to use my trailer this fixed it.

[@tomtravis1627]

That did the trick for me. Thanks for pointing out the fact that there was a fuse.

[@magicmikebangin15s64]

It worked for me. On my 08 suburban and a tire blow out and it ripped the running fender light wire out and grounded out and blew a fuse. Thanks for sharing I would of went nuts trying to find the problem. For reference on 08 suburban it's the TRLR PRK FUSE which is #25 on the diagram under under hood fuse cover

[@joshuafowler6775]

Perfectly timed! I wonder why these Chevy trucks blow this fuse. I had all three trailer fuses blown! Thanks!

[@robertkirk8007]

Thank you. Just spent two hours chasing this problem. Should have come here first. Thanks

[@jeep_freek1640]

May 12th 2023. Thank you this worked for me

[@86pmk86]

Just had this exact issue. Solved it with your video in 2’. Champion! Thanks man.

[@bobbyka1980]

Thank you I found the fuse you showed and it was blown. Popped in a new one but don't have a trailer to test it but hoping it was just a bad fuse. Again thinks for your help.

[@Locust13]

9 years later, still helping people.

[@joshm.628]

Thanks a lot! Saved me a lot of time figuring out the problem - worked for a 2018 Silverado 1500. 20A mini fuse.

[@Riddlemethisgaming]

Just got a bass boat and everything was working not the running lights..thanks👍 fixed it in 30 seconds 😃🐟🐟🐟

[@GeekyMushroom]

Thanks helped me find my trailer marker lights fuse amist the hundred or so fuses, would not guessed that is what they called it. Different year truck and build, but still a GM/Chev

[@toddsoutsideagain]

Thanks for the help! This should most definitely be my problem. I looked at the fuses inside the truck as well as under the hood but didn’t see trl park. I must have missed it👊🏻

[@BigjermsGarage]

Glad it helped! I can't believe how many people leave comments saying this video helped them. I did not think it was that big of a problem.

[@mood5736]

This was exactly my problem, blown fuse. Just didnt understand why brakes lights and turn signals on trailer worked but no running lights. Thanks

[@williamfroese6626]

I had the exact same issue I couldn’t find my TRL Park fuse I researched it, and for some reason I overlooked it That fuse was blown as well Thanks for the video

[@kennyw101]

Thanks...I was looking for a "trailer running lamp" fuse and of course there's no such thing. I was pretty sure it was a blown fuse but I didn't want to start pulling them all. You saved me some time and aggravation.

[@WhosVuya]

Don’t usually comment on videos but this fixed my problem, thank you very much!

[@phcopathicstrage666]

Thanks to you and modern technology! Fixed in 2 minutes in a Walmart parking lot at 10:30 at night

[@jcohen8956]

Great, succinct presentation. Went right to fuse, problem solved in under 3 minutes THANKS!!!

[@dc112675]

Like everyone else, I started at the back with the wires...I don't know why I didn't think to check the fuses. Anyway, thank you for the video!

[@ronaldperkins5645]

Oh my god ! Thank you for posting this ! I spent all day trying to figure this out ! After this video it took all of 2 minutes to fix ,thanks so much !

[@natebonebusta]

Totally fixed my problem on my 2000 z71. Fuse just in a different place. Thanks for doing this video, I've been looking for a fix on the running lights on my trailer for years.

[@timdykes8422]

Thanks for taking the time to make the video, offers another option to troubleshoot.

[@DrHarleyWilson]

I found some really good video tutorials on Etrailer.com that affirmed this videos pin-pointing the fuse based on the symptoms. After watching this video I went out to my Chevy Tahoe (in my PJ's, no less since it was 10p) and pulled out the "TRL Park" fuse to find it was blown. Great job to the author of this video.

[@coreybrwn839]

thanks for the tip, same thing was happening on my '14 gmc Sierra. Fuse was the last thing I thought to check.

[@didanvdo]

Letting you know your video is still providing results! Thanks!

[@heretohear8662]

Thank you! Thank you! Thank you!!! This is exactly what I was experiencing. I had finally got both Brake and both Turn signals working, but NO running lights. ...Long day under my boat trailer! You just saved me alot of time.

[@brentseagle47]

Thanks! As simple as a fuse. Completely rewired my trailer to no avail--then I viewed your video!

[@bryanlyle]

Thank you. You saved me HOURS of time on this!!!

[@crxtfr]

Thanks for the help, I just wish the under-hood fuse panel was as easy to get to, in the Chev Express 2500 you have to hang by your heels to get to the fusebox !! FUN

[@israelalonso2447]

Thank you for making this video I was going crazy in my head try to figure out why my running lights wouldn't turn on

[@brodyb8331]

great video ! I just replaced both side and think the old set caused the fuse to blow. Thanks for sharing!

[@mitchrippe3145]

really helped a lot, i only found fuses for right and left brakes/blinkers at first... thought maybe i wasn't getting a good ground and it was backfeeding through the brown wire or something and assumed TRLPRK was for electric brakes on a trailer, guess i was wrong, thanks for the video

[@stanfrank2879]

Awesome thanks a bunch I checked every wire I could think of..you saved me a trip to the shop

[@benrogers8204]

Thanks for posting! I was pulling my hair out I'll have to check the fuse.

[@rickyrivera4288]

Simple fix lol I should have know better but I was working on an old camper and nothing would work except one turn signal. Turns out the truck had two blown trailer fuses. Just figured it had to be the old trailer but nope, thanks for the video

[@jimtraveler4073]

How does this get as thumbs down? It's spot on, thanks bro!

[@jeromesolomonwashington1135]

Thank you so much for this explanation. You helped me fix a long time problem of mine. Thank you!
