2016 Chevy Silverado wt 2500 radio cuts out sometimes dash cuts sometimes no power beyond battery headlights Flicker alt power sometime reads low any help?
We need to see how you take off the Whole.fuse box and replace for a new one!
I noticed you had to remove that bracket in the corner to access the fuse box housing removal! Forgot to mention that?! It has four 13mm bolts.
Gm issues never end. My 05 yukon power locks quit working, only the locking worked. I was not able to unlock from any door.
I pulled and wiggled all the fuses and relays, under hood also and now it all works fine.
Also a bit of good advice to to all the Chevy owners to put a new ground on the engine to body. Mine was completely corroded off on the firewall.
Great video, my 2013 silverado has white powder corrosion under half the fussed and relays and under the fuse block, thinking of replacing it
Thank you. Ended up having the same problem. Wires chewed going to the ECM
And how do you remove the GM fuse box step by step , and thanks one again.
Thats what I was hoping he'd show us.
I was hoping for the same
Yeah, no. The magic of television. He just cut out the hardest fucking part. Prolly cause he swore a bunch and is shill and didn’t want to get demonetized
And the scary part is some of these new wiring harnesses are made out of organic material meaning the rats in mice love to eat the coating on the wires!
🤦♂️
05 yukon. I had major issues with parasite draw. Radio clock was at 12 everyday. Dummy me I replace the radio and that was a nightmare because other radios don't work unless you pull a tiny black on the bottom side of it inside.
I replaced the battery and everything works fine now. Even the parasite draw went away. Personally I believe the GM designed all this purposely.
My 2004 GMC Sierra Crew Cab SLE 1500 5.3 liter has been having problems with the key fob unlocking and locking all of doors. It started as a very intermittent issue and then it started being a constant problem where now I cannot open the doors with the key fobs at all. I have checked the fuses on the inside and under the hood but I do not find anything burnt out. I have also had problems with my passenger front door and now my passenger rear door giving me problems with the interior light not coming on or delaying coming on and now it is so confusing. I have replaced the batteries in the key fobs and have even replaced the push button pads but that has not fixed the problem with the Locking and unlocking of the doors. I was wondering if it had to do with the computer which I believe is also called the body control module but I may have to look under the front engine compartments fuse box to see if anything is obvious in the wires. Underneath the cover everything is clean except for a tiny bit of dust but I don't know about the underneath portion.
Hi Gents. The wipers on my ''11 1500 stopped working. Went to check fuse under hood, pulled the #36-25 Amp (I think) and half of it broke in the fuse slot (corrosion present). Any thoughts on getting the rest of it out? There is no exposed part of the fuse to pull on. Tried twitters etc. Tried to did it out, etc. Does the box come apart to allow access from the bottom?
Many thanks!
Do you have a link or anything to how change that harness that goes into the firewall
Our radio has been switching between the station and the satellite radio, without anyone touching the button. Last night when we returned home, the driver's side headlights went out. My partner checked the fuses quickly and made sure they were in place. We went back out quickly after that, then it sounded like a fuse blew and smoke started coming from that part of the hood. There was a tiny fire, he was able to blow out thank goodness. We're going to check later when we're finished work, and still have light. Hoping it's not too costly of a fix, as my car was just written off and it's going to take awhile for our new vehicle to arrive.
Do you have more videos on electrical issues for 2017 gmc canyon cc 4wd or similar
Is there a good video about the wire that prevents the transmission from shifting into fourth year? And I heard it’s pink can you show us how to get to it?
How do you remove the cover and fuse box. You kinda skipped over that part. Thank you for your very informative videos!
The cover just pops off.
I had the trailer brake fuse fail and melt the solder on the bottom of the fuse panel in the underhood box on an 04. It was driving me mad. The solder BB's would roll around in the fuse box and cause weird intermittent electrical issues. I NEVER pay to have my car fixed but that one i took to an electrical specialist and he figured it out. You can take the fuse box shake it and hear the BB's in there. Just a heads up for anyone having these issues. i had doors locking and unlocking going down the road, random no starts, lights coming on and off. it was like an electrical poltergeist.
My truck soesn't want to start every once in a while and the reverse lights stay on no matter what and my rear running lights absolutely don't work
Ive got the exsct same issues!!!
Hi I have a similar problem with my 2004 Yukon xl 1500 when engine gets normal hot I turned off and it won't start into after 45 minutes when gets cold starts. so I'm thinking maybe the fuse box is bad,but I can't find one to buy new do you guys sale that

After seeing this video I'm realizing that maybe that's a major issue with my truck especially because it's really old how much does that cost would that run to fix it is it even worth fixing
Excellent!
+Randy Owens Thanks for checking us out!
Hi I have a 2003 Chevy Tahoe I found on top of the fuses where mice were making a nest and now my parking lights come on all by themselves and can’t shut them off unless they remove the fuses or unhook the ground cable from the battery any ideas? Thank you.
I have a question about the red battery+2 fuse what is it for? I pulled it out and my truck still started normally.. I changed my hvac resistor and now I have no power to it. I had it before. im stumped and need to get the problem solved so that I can at least have a blower for my windshield when it rains.
I like ol red he always point me to the right direction
Sonoma 03 . Some of the fuses inside that box ,in my truck dosent have power .i bought it 4 years ago and my lights always have been blinking since then ...if about 7 fuses dont have power inside that box could that be normal???? I used a test light
I have what seem to be a red heavy wire attached to the fuse box and labeled as glo plug 175 ot cluster 125. It ties into a wire harness and runs under the fuse box and ti the small fuse box side the bigger box.. any how the heavy red wore has alot of corrosion on it just before it goes into the wire harness.. any bad issues this may cause?
👍👍👍👍👍👍👍👍👍 and thanks for the video
And yes, my 15 thousand miles presently 2013 Buick Verano 2.4 Liter convenience trim was parked in the same remote parking spot for two and a half months October through December 2019 in cold weather without being started ever. And I am not sure if I can be guessing that a mouse or squirrel has chewed on the engine fuse box wiring for certain. I am observing the environment and heat from my engine and vibrations affecting my Buick so far like speaker audio and rear view camera images are not functioning properly about 10 percent of the time. I don't know if I can be careful enough to remove the engine fuse box cover and take a look at it. I gently tapped on the cover of the engine fuse box cover and the speaker audio and rear view camera images started to function properly.
chevy silverado 6.0 2006 . can a fuse avoid the truck to start? I have a new starter installed two weeks ago. thank you
I have a problem with my 2006 gmc sierra 1500 denali. No power to instrument panel fuse box. Truck starts and stays running but nothing working in truck like door locks, windows, ac, radio, nor headlights. Can you tell me what would power that fuse box so i can pin point the problem? Thanks.
how do I know which fuse is the one for the electrical plugin for my trailer that I tow?
Mine was fuse box under dash was gounding out and caused to melt
@1A Auto - Hello. I am trying to program a brand new replacement key fob for my 2001 Chevy Tahoe. As mentioned the key fob is brand new, with brand new working batteries. I have followed/repeated the entire insert key, hold down unlock button, turn ignition off/on twice, wait for the lock to cycle, press and hold lock/unlock on fob simultaneously. But the lock never cycles therefore the Tahoe never enters programming mode. As a side note, I know that the locks are capable of cycling. Because when I pull and hold the bright light lever while cycling the key twice to program my desired door lock/unlock sequence the locks will actually cycle, the same way that they should when programming the key fobs. Can you please share some troubleshooting steps that might help me diagnose why my Tahoe won't enter programming mode so that I can program my new key fobs. Thank you.
+E P We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
Hi.
About a year ago I had mice get underneath that fuse box and eat the wiring, beared some wires and they shorted out the circuitry of the box, so had to replace it.
Today the fuel solenoid fuse srarted shorting out again...... may have gotten some moisture in the engine compartment.
Do you have some suggestions as to where to look for this short?????
Have you scanned it
Hey, I have a 97 Chevy Silverado k2500, Vortec V8 5.7. I was checking my fuses for the first time in a while, and I just happened to notice there's an A.I.R relay that's missing. I looked on Google I've asked friends and I have no idea what it does. Any help is greatly appreciated. 👍
How much should it cost to replace .. my trucks is slimy as well.. and wipers go off randomly and now the starter runs on....
Any suggestions on 06 Duramax diesel getting small voltage to starter when I turn my low beam knob from auto to on position? It has a remote starter installed by best buy techs. Headlights dim on driver side. Some taillight issues and rear door locks don't unlock fully when the button is clicked. Seems like power is being shorted to multiple relays almost...

You asked us HOW we were going to get to the wiring underneath. Obviously you dont know or you would have told us. I need to change the fuse block and have managed to loosen all four junction block bolts but the wiring junction blocks refuse to come out. any suggestions woud be helpful
My 2007 GMC Sierra 1500 4wd the thermometer in the mirror doesn’t work. Does that run off a fuse and which one?
For months I’ve been dealing with the issue of my driver side door not locking or unlocking. I drive a 2003 Chevy Tahoe. Any ideas or tips on what the problem may be?

I have a problem with my Chevy Silverado 2000 it won't shift out of low gear and I know it's electrical problem but I don't know nothing about the electrical stuff can you show me how to fix it somebody said it's the pink wire might be chewed off or something but it won't shift it runs good but it won't shift out a little gear
How to fix a blown fuse. I was getting a jump and the cable slipped down and touched a metal part on the battery and made a spark. Now the gauges don’t work, the steering e controls, the window locks and up/down controls and the volume u can’t hear from the radio can’t turn it up or down, can’t see how much gas I have, the battery light is on it’s never been on before and the ABS light? Is this fixable in a 2006 Chevy Tahoe
+Rachel Martinez We're always cycling through common cars. We'll add this repair to our list! 1aau.to/m/Shop-1AAuto-c
How do you replace the fuse box
We have removed two different 15 fuses that run the orange light in my 2016 yukon xl Denali
Head light and the driver side light still
Stays on and blinks after removing the fuse. It’s slowly draining the battery and we cannot figure it out
Ok, so if I'm going to play around with fuses and electrical, and computers, should I disconnect the power source???????
I was having issues with it saying i had a bad ignition relay. Also my tail lighys and driving lights quit. Smelled like urine under the cover. I had to use about 5 flat head screwdrivers and remove every relay and fuse, but I got to the circuit board and found corrosion, also found bad circuitry between the top and bottom of the board. I believe I can repair this board, but there's a bunch of little white relays on the board itself , and wonder if these will present issues.
Sounds like you have the same problem as I do.I’m about to tare into it now.did you ever get yours back together?
My trans went out, it sat for a couple months. I guess a little critter made it it's home. Now I guess my fuse panel is fried. Was doing fine, then started giving me these random issues. Started with the tail/running lights going out. Found the relay lost it's ground, jumped the headlight ground from one relay to the next. That problem went away. Then some goofy ignition relay issues, then a code for a high voltage then a low voltage ignition relay or whatever. Swapped around relays no difference. Then the whole truck went insane, and crapped out. Hopefully it didn't fry the computer too. About a hundred codes!
My tail lights won't work either . I put a fuse in the spot and they worked until i turned the truck off then never came on again. Where is the relay for the tail lights?
Hi i have a Chevy Colorado 2005 and my issue is that i don't have any power to 3 fuses that control the park and rear lights. I have changed the fuse box but the problem remains. What do you Think that could be? Thanx for the Nice video. /Daniel🇸🇪
+Evil Genius Garage There could be many reasons why you are experiencing this problem, and we would suggest getting a diagnosis from a reputable local mechanic.
what was the cost to have this changed?
I got a 2011 Chevy Silverado pick up truck the other day at the light on the turn signal on the left-hand side up on the dash did not come on so I went and bought a new switch but the screen wheel off but the new one on identical put it back to the other same thing Went through the fuses on the side there’s like 13 amateurs 30 holes all them were good then I went out I need the hood pulled out up and it was a corrosion city and so Autozone told me told me do you spray this carpet cleaner on it and there’s electronic spray on it battery cleaner I mean When I got the fusions coming out we got two of the drop off of one down inside have you ever split that you know so you can see into the bottom of the fuse is itself fuse that you push you can see the bottom of it have you ever done that can we do that
You didn't show how to take the cover box off, that's what I needed.
My question is: How do I go about protecting that fuse block from the "Invasion Of The Rodents, Etc." while also preserving access to the components that may require preventive maintenance/replacement????
+K7DFA Thanks for watching! The best thing you can do is to check under the hood more frequently. This will usually happen when the vehicle sits for a while, so if you drive it frequently and check more often you should be fine!
Dryer sheets. Mice hate them.
So who can we go to to get a new fuse box installed?
And what if they had chewed up the ends of the harnesses as well, replacing that box isn't going to fix all of it, and my truck now has all sorts of new cool features in it bc of the electrical issues in it 🐁
I have a 99 GMC Sierra, the ctsy fuse keeps blowing, all dome light are out, before dome light work fine. I notice the E-brake wire was expose n fix that but the ctsy fuse still blowing out. What is the issue for this.

i have 1988 Chevy siler i have no power to the top of courtesy box under dish help
How much does it cost to replace the whole thing all the wiring how much would it cost me
Why can’t the mouse ever be there? I once went to buy a coolant reservoir tank from a junk car. When I opened the hood got the scare of my life. An Opossum opened its mouth to expose its sharp teeth at me. It was actually in a lying down position and nursing its babies. It didn’t jump because that could mean the death of the little ones. I needed the part because my car’s was leaking bad. I slowly opened the hood again after dropping it and put the hood bar up. I slowly removed the reservoir as it was comfortably to the left of her. I then slowly lowered the hood and left. Man, when you need a part you do what you gotta do.
Not many people know about this 👍

This might be the problem with my Trailblazer
The cover comes off easy enough and I see a couple of tabs, maybe holding the top of the box to the bottom...BUT IDK. ALSO for a replacement part. "FUSE BOX shows NOTHING for my 2004. Maybe mine is too old to fix with 150,000 miles on it
Do you sale theis boxes.
+Alfred Emerson Thanks for watching, but we do not carry replacement fuse blocks for this vehicle.
My gmc yakoon get cut stop at road
Just popped my fuse block up. Acorns an chewed wires lol
You didn’t show how to get the circuit board off of the wiring harnesses.
I think Chevy and GMC truck have transmission issues
Can this cause a car not to Start ? Because mine doesnt and I checked the fuse box and gave it a gentle hit and it started on but then again it wouldnt again
Did your figure it out my truck just cranks but doesn’t turn over unless I put starting fluid into the throttle body
Headlights don't work fuses are good relays are good balls are good connectors are good
No Mice in my 2013 but lost my wipers, now seat belt restraint system no signal, Truck has gone into limp mode in wet weather a couple times. I think its related to the Fusebox. I hate to throw parts at it but what a POS design
