2007 GMC Yukon Denali Headlight Relay & Fuses, Fog Light Relay & Fuse 

Thanks for the great descriptive post. I had just one high beam that did not work on my 2012 GMC Yukon. I did not know there was a fuse for right and a fuse for left . I pulled out the one that was for the left and replaced it with a new fuse and it worked. Thanks!

Very helpful and detailed. Also, using proper grammar while explaining stuff is greatly appreciated. Thank you!

I got an 08 escalade. I get no power to the front turn signals but I do on the mirrors and tail lights. The two top lights above my regular headlights don't work. Checked fuses and all of it seems to look good tho. I'm stumped.

Thank you very much. I'm working on my uncles chevy Avalanche and this is exactly what I've been trying to look for. I thank you

Aloha have a 2007 Cadillac Escalade which fuse is the radio and the CD player. Thank you very much Sal.

I noticed so many people commented to you video and didn't reply to anyone

Hey do u know where I can find the Signal relay fuse.. my signals don’t work and can’t find the right video for my problem..

I have a 2007 Cadillac Escalade ESV. My problem is that when it rains my parking lights won’t shut off. I believe the fuses are #’s 25/26. If I take #25 out. The left side cuts off. If I do the same for #26 it won’t shut off. Anyone else have an electrical bug like this? And what did you do to fix it?

After a jump, due to weak battery as a result of long parking, my Cadillac Escalade 2008 (Exactly same as GMC you show here) does not show in dash backlight so I can't see any reading, at the same time, all four gadget levels are turning On and Off with blue light! Any suggestion as to what should I do?

Thank you! Saved my ass last min before work. Fixed in two min swapping relays for low beam. You rock

My neighbor had me test the left side low beam of his Cadillac now the led headlight doesn't work all the fuses look good any help.

Any idea why the lights go out when using the right turn signal? I just replaced the multifunction switch and still have the problem. TIA

Great video

My daytime running lights won't turn off ?? Where is the drl relay or module?? Located thanks

I have an 07 Tahoe, the driver rear blinker light works but not the parking light itself . Is there a fuse for this? Or would it be prong/wire related?

i have a 2003 denali and the fog lamps on both sides just quitworking the button that turns them on on the dash the little light comes on so its getting power i think. its jusy weird that both went out at the same time so i dont think its the bulbs. any advise of what to do to repair this issue

You know the fuse or relay for signal lights?

Can you show me where i might find my reverse fuse on my 2007 Yukon? " I have no back up lights.. the fuse i found is fine under the hood .. I checked bulbs over and over.. I'm afraid that it maybe the switch on the transmission which location is not found, I don't recognize it ... Or maybe a ground if it is ugh" where do i start ? Thanks,,

I have a 2007 Yukon my headlights don’t go off after I turn switch off and lock doors what could cause this

Do you have a video for brake lights?

Thanks for this. I thought the daytime running lights were the same as the headlights?

this simple relay swap worked! thank you!

I added led high and lows I kept checking after each install and in the last one my auto feature stopped working? Any ideas also got a p0113 but I think it's where I had the sensor unplugged for a few

muchas gracias amigo!!!

no one know where is turn signal flasher relay

Hello there I have a 2021 Chevy Tahoe z71 and my low beams are not working, I replaced both bulbs and they stopped working again and my high beams still work, checked relay and it’s fine , fuses both replaced any suggestions? Stuck with no low beams what to do? Thanks

Im geting a eletic shock from the cigerit litger

I replaced my bulbs with LEDs and I don't want to add Resistors to each Turn signal, do you know what kind of relay I should get for the blinkers for the yukon?

My daytime running lights are not working on my drivers side of truck. I have a 2016 gmc sierra 2500 and I cannot find any fuses labeled DRL.. I started by checking all of my fuses under the hood and in the cab and Nothing is burned out. Where should I look next? I cannot find any youtube videos related to this that can help me.

Ey my taillights don't work thanks

On my 09 tahoe low beams and daytime running lights wont work any suggestions

What's wrong if my low beam is out,my seat warmer and my window won't go down on driver side and my signal light all on driver side..2008 Yukon Denali

I have some HID headlights and the driver side isnt lighting up. The high beams are but the low beams arent. I check the fuse and relay everything is good. A while back i had a bad balace and replaced it but i think something my be burning out the balace (extra power source to light up the hids) could you have any idea what it could be?

Great video , is there a fuse for the parking lights ?

My gmc passenger light is not as bright as the driver side my driver is very bright but passenger side is extremely dim any reason why?

What if your fog lights won’t turn on it’s not a bad fuse and it’s not the bulbs on a 2011 GMC Sierra

I don’t seem to have power to my night beam fuses any suggestions?

Only my driver side won’t turn on I replaced the bulb

Thanks, good video. I have a question for you. I have a 2010 GMC Sierra. The high beams come on but the low beams don't. You won't be able to help me what the problem will be.

I recently just took my dimmer switch out of my Yukon and cleaned it because you know how they get some times I also installed new fog lights and they're acting in tandem with my low beam,and parking light switch I'm not sure if I missed a part when putting my switch back together or what happened I had no idea they were wired in together but something's going on wonkey

Thanks a lot for your good Video. I have one question. Booth DLR and Tail Lights want work on my Tahoe 2007. I was checking this to 15A Fuses for DLR and booth are ok, but if I turn the light on or start my car, there is no 12V on these 2 Fuses. Could it be that the Headlight switch is defective, or is there another part (like a relay) that could be the problem. Thnaks

My Headlights were working fine on my 07 ext escalade and I run it threw the automatic car wash... now the lights won't automatically come on however if I turn the switch manually they work....

Good vid bud. Question.. Im running into some issues with the puddle lights on my 09 yukon. Does the puddle lights have a fuse as well or is it intermingled with the dome lights. Thx in advance.

I'm not getting low beam on driver's side. Which wire in the harness controls it. 08 Escalade

So my lights on a 2016 denali turn off do u know what could be the problem. They turn off n I have to turn the button to turn back on every 2 minutes or so. Can u please help? Thank u

Hoping you can help, I installed h13 LED's in my 11 Yukon and I've normal high beam functionality is there a fix???

I know this is for the GMC would you know were the relay is for a 2007 esclade esc ?

I have an 07 Yukon Denali all my lights work tail lights turn signals everything but running lights and license plate light my fuses are good try to replace relay getting ready to replace tail light circuit board any other suggestions

Great video and very informative... I have a 07 Ext Escalade... Drivers side headlight went out... checked my fuses all good... changed the relay.. I still have nothing so changed the headlight bulb and the ballast and it still doesn't work... I don't know what to do?

Thank you so much

Any idea why is my daily and night lights are on all the time on a chevy tahoe 11?

i have 2007 Yukon Denali i did every thing i know lights is dim any idea what to do how to fix it?

My dash lights don’t work. Where are the fuses for that?

I have a problem with me 16 Denali 1500. My fogs won't turn of they will dim and flicker

Thanks for your help.

Thanks for the video! I have a 2008 Yukon Denali, both low beams just went out. High beams work. Swapped relay and checked both 20 amp fuses, all seem OK... could both bulbs have really burnt out???

I have a 2006 GMC Yukon, she runs great she's in real good condition, even still looks good, but last night I noticed that when I hit the button to let down my windows up,or down, my headlights went kind of dim, then when I let the button for the windows go,they brightened right back up, I've never noticed that before so I'm not sure if it's always done that, is that something that supposed to happen or is there something I need to do to fix that

Thank you very much you help me out a lot

#30 fuse inop but other fuse working for drl and drls wont turn on...any help t.i.a

2003 Yukon--- High Beams come on when I engage the right turn signal

Great quick video, question though. My Yukon has both left and right front signals out and when I put the blinkers on it is very fast…is there a fuse for the blinkers? I mean, the chance of both bulbs going bad at the same time is highly unlikely right? Thanks!

Location of fuse for all the interior lights

How about gal's?

I have a 2006 duramax. No high beams. Both fuses are ok. Swaped relay but problem is still there. I can hear and feel the relay clicking. Im NOT getting 12 volts to the high beam fuses. Any suggestions?

What fuse number is your Fog Lamp?

Any advice on why my lights still aren’t working after replacing the relay and swapping all fuses involved?

Can you please help me???? I have a 2011 chevy silverado 5.3 4x4 and I don't know what to do or what to check next. All of my lights work except my high beams! I changed fuses, hi/lo headlight relay, multifunction switch, bulbs. No power at fuses. My indicator says the brights are on but nothing... Please help. Thank you!

Life saver!!!!

Thank you 🙏

One of the best to the point videos I’ve ever seen!

I have a 2012 Tahoe and the backup lights don't work. I check the #15 fuse and it's good. The bulbs are good too. On the wiring diagram it shows a relay but I can't find it. Is it one of those that's part of the fuse block that you can't see?
