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.

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!

And how do you remove the GM fuse box step by step, and thanks one again.

[joeymondillo]

Thank you. Ended up having the same problem. Wires chewed going to the ECM

[davidfry]

How do you remove the cover and fuse box. You kinda skipped over that part. Thank you for your very informative videos!

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.

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.

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?

I have a 96 Chevy pickup I need to replace fuse box. Due to sitting and corrosion. I will be giving you a call to order

[juanmoreno]

Do you have a link or anything to how change that harness that goes into the firewall

[crazycanadian]

[lorrainevalencia]

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

[brianfox]

Thanks for the great tip for the fuse box and keep the great videos coming

[robbw]

I just had this exact problem on my Silverado. It completely died on me while driving and would not restart. It would crank but not start. I had to have it towed back to the house. The mice had been making my fuse box a home. I ended up replacing the fuse box, it isn't hard, and it fixed the issue. Now, how do I keep them out of there????

I'm having issues with the driver side low beam headlight I've changed light bulb and tested fuses fuses are not blown but not getting power to a few of the fuses that say highbeam I'm stumped I thought might be a fuse box issue but it's only the driver side low beam headlight 2015 gmc terrain 2.4 motor
