extremely helpful video . brake light wouldnt turn on then caught this video and low and behold that 25 amp fuse was blown out never would have thought it had that fuse and the one inside the truck
You totally saved my backside! I had older LED after market lights that shorted and when intalling new ones couldnt get brake lights to work. Went through everything. Your circuit and fuse walk through helped me locate the 25a in the dash that was blown. (not to mention a few 10a) Thanks!
Fun fact. Screw that clips. I replace my brake light switch, installing the new one the clip was being a pain. Then it pings like a clip from an m1 garand and launched itself up into the inside of my daah. 30 mim later i finally found it in some part of the framing back behind the steering wheel. Pain in the ass. Do not lose that clip!
All of my fuses work I just bought a tail light power distributor and harness for the right side it fixed my turn signals but not my tail lights/ break lights. What do I do???
I have an 05 Sierra 1500 and my brake lights light up when the marker lights turn on. If the headlights are turned off the brake lights work normally. But if the headlights or marker lights are on the brake lights illuminate as well
I checked the fuse under the hood- good. I checked the fuses inside the cab on the end of dash- both good. I changed the brake switch on the brake pedal. Still, the brake lights don't work. The 3rd light on the cab lights up when brake pedal is pressed. All other lights work. What's next? Please help. Thanks so much, Roy
@@reygonza3740 Yes, look up your rear tail light circuit board. Very easy and cheap to fix. It's where all the rear lighting harnesses plug into. The inside pins rust or burn out. Let me know if that helped!
@@reygonza3740 Your comment about the parking fuses saved me a trip to the shop. I have worked countless hours replacing hiring harness cords, testing bulbs, and replacing fuses. I was about to start examining the master cord that transfers current from the hood to the tailights for any broken wires. Thanks for the tip.
Hey question as Im doing fuses in same make and model what goes in that empty space with metal sticking out you have nothing there now and mine is empty too but not sure if I need to put a rely there or what or no or whats it for?
I’m having a difficult with my Chevy so my brakes wont come on when I press it or when I put it in reverse my reverse lights won’t come on but if I turn my emergency lights on they all come on. i replaced my brake pressure sensor , I changed my fuses and I replaced my tail light combination junction block and still got no answers
Hey so I got back lights on and I got left and right turn signal but when I push the break pedal down the back lights don’t work for that tho..? You know why
So I have a 04 Silverado 1500 I checked fuses the top brake light will light up and however the left and right will not when I press the break fuses look good I will double check again but if it’s not that then is it what your changing out or could there be another problem
I have power to the two 10 amp fuses even when brake is not pushed. Changed brake switch/bulbs and still no brake lights. No reverse lights either. Help!
Ok but you u please tell me why only one side works well driving, both rear brake lights will come on when the brake is pressed just not the passenger side well driving, any help is much appreciated
There's also a circuit board (gray block) located at the end of the truck under the bumper on the left side. This powers all the lights in the rear. You might have a bad pin connection. Also the harness might be bad.
Ohm test, 6 pins in sets of 3. Two normally closed one set normal open. They should change by pushing the black button. Or the fuses are good and the lights don’t work. Switch or wires, that all that’s left
Question? I replaced my brake light switch on my 2000 GMC Sierra 1500. It looks exactly like the one in the video, same fuses, brake pedal and brake pedal rod. I switched out the brake light switch and now I have no brakes. The pedal is hard to push and basically will not stop the truck. The fuses are good, the switch is good and I replaced the switch correctly and even put the old brake light switch back in and still no brakes. It is like I need to bleed the brakes or they are air locked. The brake pedal is stiff and hard to push down. I can take the reservoir lid off where the brake fluid is and pump the brake and it acts like it is not pumping, because the fluid does not squirt out of the reservoir. Do you have any idea as to why it may be reacting this way? Help appreciated.
@@MrBlindMode yep, I figured it out and changed it; weird though, how changing out my brake light switch made my booster go bad. Still haven't figured that out.
I need help, I have a 2007 GMC Sierra classic every light works except for the right taillight and license plate light. The “broken” taillight works when the blinker and reverse light is on however the running light doesn’t, it is not the bulb and I have checked the fuses.I have also replaced the harness and junction box.
Why is when i put brake switch back on the brake lights stay on. I changed the brake booster and now the brake lights stay on when i put the switch on. I pull it off the brake pedal the brake lights go off . I changed the switch with another one and it does the same thing. Any reason why ? Maybe the new booster rod is thicker then the old one and pushing the switch in more when i push it all the way on brake pedal

What A Great Video.
I Got Screwed. I Should Have Seen This Video 1st. Thanks So Much.
I know this was two years ago... but would a switch be a problem if the center light on the back of the cab works while the others dont?
I’m having the same issue right now. Center brake light works but others won’t? Did you find the solution ?
@@9492ninodid you? Same thing for me
Did you find the solution I’m having the same problem
Did anyone figure it out
I guess not
Thanks man! Much appreciated!

Did you find a solution for this? Having same problem
@@AlexMartinez-wc3gu yes it turned out that my left brake light bulb was the incorrect bulb
Ok will that switch be messing only one side or both??Cause mines is only the driver side the other three

Thank you
Hey this is prob going to help a lot but I need to know if one of those fuses are for the taillights as well
My third break light still works and the fuses are still good that’s means it’s the break light switch or what
I have the same problem third brake light still works and not he back taillight brake lights tried replacing the bulbs it didn’t work
Same here I have the same problem. If anyone knows what’s wrong please help
I’m here for the same problem since I got aftermarket tail lights
Anyone solve this problem yet??
I’m having trouble with getting power on the red wire going to electric break box. All my fuses are good. Do you have any suggestions.
Thanks good stuff did not about the three fuse
I don’t have turn signals at all , or brake lights but my flashers work and my running day lights any pointers u can give me?
Thanks.
My break lights are not working I just change the fuse but my third break light is working just fine
Hey question as Im doing fuses in same make and model what goes in that empty space with metal sticking out you have nothing there now and mine is empty too but not sure if I need to put a rely there or what or no or whats it for?
and the other empty rely spot too this is on the drivers panel Im talking about
So I have a third brake light working, but rear brake lights don’t work. Replaced my BLS, circuit boards…… what do you think
I’m having a difficult with my Chevy so my brakes wont come on when I press it or when I put it in reverse my reverse lights won’t come on but if I turn my emergency lights on they all come on. i replaced my brake pressure sensor , I changed my fuses and I replaced my tail light combination junction block and still got no answers
Hey man im having the same problem did you ever figure it out ?
God bless you
thanks man!!
Hey so I got back lights on and I got left and right turn signal but when I push the break pedal down the back lights don’t work for that tho..? You know why

Best video I have found for replacing this switch for my truck. Great lighting also. Not sure why you cut the wires though LOL
Thanks brother. I cut the wires so I could more easily film the video with one hand.
I have power to the two 10 amp fuses even when brake is not pushed. Changed brake switch/bulbs and still no brake lights. No reverse lights either. Help!
Ok but you u please tell me why only one side works well driving, both rear brake lights will come on when the brake is pressed just not the passenger side well driving, any help is much appreciated

My brake light work but cruise control dont so hopefully this will solve my problem
Did it solve it ? Same issues
Yes
What fuse is for the reverse lights, my reverse lights don’t work
My third brake light stays on while being plugged could it be a faulty brake switch ?
Do u have one on the running lights not working
Wouldn this b the same as a 2001?
I have an 01 Yukon xl they are the same because I put one on mine but the brake lights still want come on. Fuses & bulbs are good.
I just replaced mine 2x now again not working. Mine is 06
I done all this my rear lights work but do not brighten when pushing brake but my tail light does come on
Same! Find the solution????
how do you know if the brakelight switch is bad?
Ohm test, 6 pins in sets of 3. Two normally closed one set normal open. They should change by pushing the black button. Or the fuses are good and the lights don’t work. Switch or wires, that all that’s left
Already change the brake light switch and it still ain’t got brake lights
Same for me I change it twice fuse check wire check what else?
Im guessing wiring or bulbs. My 3rd (on back of cabin) light works just not my 2 main brake lights.
@@kevinaguiar1332 i will Check The wire but when I got a trailer the stop brake light work on the trailer but not on the truck...

Thank you very much for the video, it helped me a lot ..!
Does this fix the issue with only one side of my taillamps working?
Mine is the same only one side work did you get yours fixed?
@@ashliemoy8814 did you get yours fixed? If so how
WTF. pulled all the fuses.. 3rd brake light is still on
I spend a LOT of money on the stupid GMC factory printed paper shop manuals, they are huge and 5 volumes. It says "remove the clip." THANKS GMC NOT!!!
Part number ?
Didn't make a difference ☹
