You're a great diagnostician, Eric, but you're an even greater person. God bless you, Eric.

I'm a Mechanic by trade myself, I love to see and learn issues I've never ran across and even gain more knowledge. I appreciate what you and God Bless 😎

My wife Malibu is literally doing this right now and stuck at my job. My mechanic and I are really trying to figure this thing out. I'm going to show him this video cuz this video magically showed up in my feed. These phones really be listening hint hint 👍

You have saved me hundreds if not thousands of dollars and valuable family time that I would have spent replacing damn near every part on my truck until I came across your video and the fuse box issue and it put me in the right direction in fixing my issue. Thank you very much!

Love the explanation and detail with the wiring diagram. That stuff right there is gold for DIY's like myself.

I’m so glad I came across this video after the car was in the shop for about a week and a half and they could not figure out what was wrong with it. My sons car is a 2012 Chevy Malibu and the mechanics could not figure out what was wrong with it. It was the same issue. No crank no start but you could jump it to get it to start. We ended up purchasing a new fuse box, direct from the Chevy parts dealer in town. When we took it in for service to Chevy, they did find the exact same code, but they said that the fuse box was on national back order. We were able to go directly to the parts department and pick it up the next day. The parts guy had it brought in from Arizona within the day we picked it up and took it to the service writer. He was stunned that we were even able to get this part. I guess service dept and parts dept do not talk to each other at that location. So if you take your car in and the service writer tells you a part is on national back order. Just call the parts department on your own and do your own research. The part was almost $500 and it was just around $200 for them to install it. We took the old fuse box apart and found the fractured copper wiring. Thank you so much for this video.

I never got a code but had no crank no start after warm up. Took fuse box apart heated the wiring and checked continuity on all wires. Identified discontinuity on one wire ,magnified and found broken wire,soldered and so far so good 👍 thanks

You SMA and Ivan are the ones who "fix" the problem. Great tech tip with the heat gun! I've used mine in the past to locate a problem. Another way to temporarily repair it would be to run an external wire from the relay socket to the wire going to ground. Not the best way to repair it, but better than having an intermittent problem until a new box is available.

I applied what you taught me on a pin-drag test for a Silverado ABS problem, similar year to yours. It cost me 0, abs is back in business. It's a similar story as to the fuse box issue. Thanks a million.

Nice job. Should be a recall and a free dealer repair. Difficult diag, intermittents are the worst.

I'm the dealership tech and thank you very much. Have caught a lotta fuse block blunders but this one has me in circles. Thank you sir and God Bless 🇺🇸😚🙏

You are very good at this. I can see most of things you do is electrical work and flood cars. Most mechanics don't want to bother with electrical stuff, but you do. It just shows how competent you have become over the years. you inspired me to learn wiring diagrams after Tundra Fuel pump video. Thank you, awesome content.

I used to use Heat Guns and Freeze Spray when I used to repair Medical Equipment back in the day. I had Patient Monitors that would stop working. I would heat up the capacitors and the display did not work and when I hot it with the freeze spray the display would work again. So I was able to repair unit with a couple of dollars of parts instead of replacing entire circuit board. Great catch on your part with this issue.

Your wiring diagram explanations are at a different level than anyone else, thanks for taking the time to include them.

Awesome diagnosis! You did a great job explaining everything too. You're a natural teacher. Thanks!

This is the kind of diagnostic video i wanted to watch. You show everything in detail! Thank you.

Bro you’re top notch and super smart I wished I understood electrical as much as you I’m working out it. Thanks for inspiring.

One of my favorite diagnostic tools for intermittent issues. My wife’s blow dryer

That generation of Malibu’s are terrible cars. Even changing a headlight is an extensive task. Excellent and detailed video, keep it up.

This has been super helpful- I sent to my mechanic after an intermittent no crank no start issue. My mechanic found several cracks in the fuse box leads, and we now await a new part with a way forward to fix the car! Thanks so much for this info and a great video.

Talk about finding a needle in a haystack. Hopefully a talented electronics person sees your video(s) and decides to design and sell an improved replacement fuse box circuit board for this common problem. Thanks for the nicely detailed video!

Many starting/drivability issues with the malibu stems from the faulty fuse box. Great diagnostic !

Eric it is problems like this that makes you an exceptional tech among your piers.

This is amazing. Back in the 90s I used to own Ford Tempo that had similar issue. After engine heated up it shut down. It was intermittent issue. Mechanics couldn’t figure out what the issue was. It became process of blind part replacement that costed money. Now, that I see this video it was eye opening how it is truly easy to misdiagnose the issue. Thank you Eric for sharing all these valuable information. 👍

You should have your own shop.. you are worth the dealership price. Nothing worse then going to the dealership, who you think should know how to fix issues like this, paying high price diagnostic only for them to give you a dumb response, hold your car for weeks then end up having to return it for them to charge you more money. You a real hero... you should post a wallet tag so people can donate money to you... not cause your doing it for money but cause people like me really want to show you how much we appreciate you.. im literally writing this while sitting in my 10' malibu that WONT crank and furstrated of why I cant solve this issue... then I come to you tube and my hero (you) save me with knowledge.. appreciate you .. 🙏 YOUR FAMILY SHOULD BE PROUD... YOU REALLY ARE A HERO

Great diagnosis. Your explanation of the wiring diagram was excellent, too.

Couldn't agree more... Comments stating how much a video helped someone, is a motivational reason to make more videos, and gear them towards the DIYer. Excellent explanation as alway Eric!

Great video. Your troubleshooting skills are right up there with the best of them.They are so good that they can be applied anywhere. Thank you for sharing your knowledge.

As an ASE master tech since 1978, working on everything especially electrical. I used 4 home made jumper wires to connect the relay to the fuse / relay center. At this point, I can check voltage drop across 30 & 87. I can check the coil side to ground to see ground or ground plus drop across the coils internal resistance. You are correct in the way the computer spends 4-5 minutes checking each circuit. But if good when cold, it passes the test and moves on to next. TBS are generated by a high fail rate, parts sent in and engineering looks to find the root cause. It they have 40-60 dealer techs per day calling with a similar problem, they will give then 2,3,4 items to check. Once again, if a tech finds this issue, then they are sent a replacement and shipping label to get the fuse / relay center assembly sent back. If the get a number, then it is re-designed, new part number for the part and included into the “TSB”. You can use a jumper wire to bridge the break as that would stand the expansion & contraction. But call the dealer, ask for the service manager and be honest about having video, VIN numbers and ask if the regional service manager can call you or speak to the technical hot line. Now, there are more than one dealer out there, just like customer service at any company from Ford to Summit, sometimes you get a person that is good and will to help, sometimes they act like you are bothering them, and get no where fast. Also, the back of the owners manual has a GM customer service number and they maybe able to get you to the right folks. I worked on contract labor for Raytheon but was in the field as an ACDelco service rep. We had the power to make phone calls, send photos or video into the department that handles fuse/relay boxes. Locally, you will have a warehouse distributor that sells Delco parts to the dealer as well. They to know how to get an ACDelco service person who may take interest in your finds. I know it’s a lot of work on your behalf and no one at GM is going to send you a new Corvette for finding this issue but don’t give up!!! ACDelco ex-Market Area Service Manager, but one of 56 nation wide who did hands on classes and held technical seminars for shops the warehouse distributors invited to attend. Yes, some of us were ASE Master Techs and had L1, P2 as well and owned a tool box and made our living once fixing cars, but not all are the same. It is hard to find someone to spend 243 days per year in a hotel holding seminars, teaching and dealing with returns. Plus, they have cut most of those jobs! Great video and just remember that using a headlamp bulb that draws 4amps May heat that circuit better than a heat gun. I will tell you, Thanks for your efforts!!! Parts on national back order as it is being redesigned and beefed up perhaps. So the 2013-2016 did not have this problem! DK, Omaha, retired!

You’re amazing ! GM owes you a big reward for finding this problem.

This should be a class action lawsuit. My line was cracked at the same location. And paid for multiple parts and it never gotten fixed until i watched your video. I bought another fusebox on ebay and checked it thoroughly. I looked at the old one and realized it was already repaired before or remanufactured because the sleeves weren't square at the top. It's a common problem. I would get no crank after the car would go into reduce power. Oh i used a socket extension and hammer to knock the 4 bolts out on a secured platform 5 minutes top. Then i used the bolt on the opposite side to push the sleeves out with an extension and hammer.

This guy is indeed a professional and! Thames for all your help,awesome work.God Bless

Super video, sir. I just watched PHAD vid where a module with bad solder joints would result in no crank no start. Reflowed the solder to create a good electrical path and everything is good. No Parts Required!

Thanks again I bought a new starter and new battery. My car is doing the same thing. The electrician could not fix the problem....

Eric I could listen to you all day!!! Great info thank you!

Eric si es chingon, encontrar ese problema no es nada fácil

I remember that video. I always keep it in mind because my youngest daughter drives a Chevy Malibu and you never know with this model fuse box. Thanks a lot.

I have learned so much from watching your videos. You do a great job at explaining and it helps me understand what’s going on keep up the good work

Genius craftsmanship, a true practitioner.

impressed that you found time to not only read but also answer my comment . I didn't think of the wire under the relay pin because i'd be worried about over flexing the female connector in the fuse box but if you were going to replace the fuse box or for a road side emergency I could see it.But it would suck if decided to solder it and it didn't work right because of a lose pin fitment problem. Great work I regularly watch south main auto and fordtechmakuloc because of their knowledge and thought processand I'm going to add you to that list. THUMBS UP EMOJI

Fantastic diagnosis, Eric! I'm sure you are helping a lot of folks who are having this problem.

Hello. Thank you so much for your video. My granddaughters needed their car for school. We were at wits end. My husband changed the starter and checked the battery and the relay. Nope...that was not it. My granddaughter was stranded for 45 minutes before the car started. I decided to look on Google and ask questions and guess what I came across your video. Thanks so much. Continue doing God's work. God's work comes in all kinds of ways.❤ OH, and by the way you made it so simple I could have done that.

You helped another one years later thanks so much keep it up much love....

HI, YOU ARE # 1 IN YOUR TECHNICAL APPROACH BLESS YOUR HEART FOR THAT. THANK YOU.

Thank God for your video I replace the starter on my car thinking that was the issue it wasn't!! Here in Texas it's so bad I get one start and then that's it you've helped so much with this issue I have thank you it will be fixed now

I thinks that is the problem on my car on It has ruined my life and job prospects and bankrupted me Thank you so much !!!

Eric, God Bless you, and the guys that do this on U tube, It's such a great help to some, an educational to the rest of us. Knowledge is Power, Be safe and thanks.

You are right , you are an excellent technician and even a guy like me can not explain as clear as you did and really took the Time to show us in detail s , where to look and what to Do to solved the issue . Many many thanks .

Just came straight from watching Pine Hollow Diagnostics video "Lincoln MDX 4 amps parasitic draw" Ivan's channel to watch yours. KZfaq offered at the end. I'm going to continue while I am making lunch! Great content Eric, Cheers!

😊😊 first of all I couldn't find anybody to sort that wire up under the junction block but I ended up having to buy a new junction block AKA fuse box and that exactly what it was KEEP DOING WHAT YOU DOING MY 2011 CHEVY MALIBU LTZ RUNNING LIKE IT'S BRAND NEW THANKS AGAIN YOU TAKE CARE!!!!

I absolutely love ❤️ how you and your beautiful family have grown and how much you improved since you started KZfaq. You are doing an amazing job here’s to 2022 👍🏻👍🏻👍🏻

Nice video and thanks for taking all the time to show the fault.

This was a very interesting problem Eric! Good to know this seems to be a fairly common problem. Thanks for the video and instruction. You are a very good teacher!

Great work man, reminds me of my college days with diagnosing circuit boards

That's really smart of you to know the power probe was too sensitive! Thanks alot. U the man yo!

Thank you for your good-hearted desire to help. And, you are very helpful, with complete, understandable explanations. Thank you, my Good Man.

Great diagnosis Eric! Thanks for taking us along. Cheers!

If I was the car owner you would be fixing the box , really good video !

Bought a new fuse box solved the issue immediately, did it in March 2022 , still running strong

Very well done diag. Experience is a great educator. Will keep this in mind if my 2013 malibu exhibits any symptoms.

Eric, I cannot thank you enough. If I had your zelle I would pay u. Between this video, and ur first, it helped me out so much. I do hvac by trade so please if you ever come across something in that field message me! This is the kind of tech u want working on ur stuff. You really know your stuff and took your time diagnosing. Brilliant video thank you again!

Thank you, my wife has, 2014 malibu I know this problem is coming I just purchase Top don phoenix pro I just want to say thank you I work on my family cars, and I would have bought a new fuse box and that would been very costly I been working on cars more then 20 years and you are never too old to learn something from younger generation. God bless !

Great Job, Eric! I remember watching your original video with the fuse box issue. It’s disappointing that GM doesn’t acknowledge reoccurring design flaws, especially with electrical. For that reason, I’m sure a NEW replacement fuse box will fail the same way. Your customer is probably better off paying you to repair it. Thanks for helping the community of professionals and DIYers!!

Great video as always Eric, and big up for you going back in time to remember the first problem and linking it to this issue. Keep up the good work as always Eric, keep the videos flowing, really look forward to them, always great content.

Excelente diagnostico Eric gracias x compartir tus videos.son de mucha ayuda.👍

I don’t even have a Malibu, yet I watched all 30 minutes of it. Oddly therapeutic. LoL Great Job bro. Hopefully customers don’t try to low ball you because of your knowledge.

Excellent diagnosis bro very thorough explaining things!...I can't say enough about ur skills ...keep up the good work!

I have no doubt at all that your videos have helped tons of people. I have a lot of respect for you and what you're doing here on KZfaq. Cheers.

Very informative and thorough. Thanks for taking the time to lead us thru.

Wow! Thanks a lot. I already wasted $230.00 for ignition switch replacement and just ordered a starter ($70.00). I looking for where the starter was located and how to replace although I didn’t think it was the starter. Then I came across your video and I’m so glad I did. After watching your video, I realized that every time my car would not start was after sitting in the hot sun all day or after a long drive on a very hot day. Now I am going to try the heat gun test before I change anymore parts. Thanks a lot.

Very useful and helpful .thankyou for so much headaches and pain and aches. You saved the day again. 💪

This is info on hand is well needed thanks brother

Grade A explanation and breakdown, Your videos are the best out there!!!!!!

Good points! I’m working on one as well and it’s doing the same thing. I will test the box . Thank you for this video!

You are a genius mechanic 🧑‍🔧🌹

Very nice work finding a non-obvious fault. Few shops are skilled enough to find intermittent electrical failures, especially something as subtle as a cracked wire in a fuse box. My sister-in-law's car is having a crank but no start problem and perhaps this will explain the problem. I'll try some of your suggested troubleshooting tips. Thanks.

Wow! I am so impressed by your diagnostic abilities and your detailed explanation of how a relay works in relation to the ECM and what it does internally, how a fuse box looks like taken apart, and so on and so forth! Needless to say I subscribed to your very valuable channel!

Stellar video ! Dang , this fuze box issue , has been such a thorn in my side ! Replaced it , car started working again, after disconnecting the battery today, after pulling a fuze , it wont turn over . Crazy engineering ! 🤬

I have learned a lot from this channel!

Great video! I don't often see modern GM vehicles with faulty fuse boxes

Your the best man. Thanks for being honest and reliable. Your the best . God bless

Great video. At the same time it makes me sick to see such a problem. I have a 2012 with 95,000 miles on it and it hasn't had this problem yet! Fortunately I had a career working on electronic equipment and I did surface mount soldering on circuit boards under a double eyed microscope. I hope I don't have to use my soldering skill on my car.

Going through the same thing on a malibu my gm buddy looked at a diagram and said Ignition Switch is hardwired to the bcm that sends a signal to the pcm that finishes to the relay that powers the signal wire to the starter which I have no power to the trigger wire but all fuses and relays are good and said it's either the Switch bcm or pcm so ill definitely check under the box highly appreciate the video thanks 🍻 the box is cold and still doesn't start so it may be broken beyond temp control I hope soldering can fix it its a rough vehicle but all they have for now and doesn't have much money

Thank you for making this video! My son has a 2005 Malibu and has this issue.

Great job explaining the issue, Great work!

Very very nice diagnostic with good explanation

From rio grande city tx 956 🌴 today you made my day 👌 just fixed it my self after a week with out car ...

This is probably the best video I've seen on KZfaq..I've watched 1000s of them and this is the 1st time I ever left a comment..matter of fact I didn't even know how to leave comments..you explained it so well and didn't fool around with the neighbors dog or here comes my wife Jane etc.etc..I don't even know why I watched this video because my problem is with a 2015 buick lacrosse with a no start that is making me crazy..but anyway thanks again and keep up the good work!!

Excellent demonstration!

Very good explanation and demonstration appreciate your skill level great 👍👌💐🙏

Great video. Usually videos like this get confusing at times but you made it very clear to understand. Keep up the good work! Subscribing to your channel for sure. Thanks bro!!

this is very informative and excellent explanation well done

Wow , Very educational , and good hearted . You could have keep it to your self but instead shared it with the rest of us diyer

Thank you very much for this video I completely ripped out my starter and tested it and it was fine thanks for the heads up

Great Video, I will keep this in mind for my 2012 Malibu.

Best car channel on KZfaq 🙏

Your amazing bro and thank you for this cause it’s what I couldn’t figure out in this Malibu !!! Your the best keep up the good work

Good job! Best fix is the same as Mopar fuel pump relay. Take relay out of fuse box. New relay & socket separate from fuse box.

Very well done eria gm knows the fuse box is crap some one needs to take them to court. Thanks eria very well done my friend. Sam

Your amazing, dealerships are scary, I'm impressed
