Sorry guys, our donkey powered internet has been on the short bus to Struggle Town. Hopefully it uploaded correctly...

$500 for a true diagnosis and permanent fix of an intermittent problem sounds like a steal to me. Great job tracking down the issue.

Wow that was an epic diag, Wes! Intermittent issues can be an absolute bear lol. Definitely key to determine what conditions make the car act up, and test it in those conditions... Even in the snow or rain or brutal cold 😉

"The problem is extremely intermittent..." man, that is always such a pain... you are really good at what you do Wes! Respect to you! (and I strongly believe your thoughts about moisture are correct)

Fellow wrench thrower here. That spot is very common to rub through on the fuel rail and cause typical chrysler fire problems. Usually after the 5th or 6th hemi engine swap the tech will notice both sides doing the same thing. One of the wires in that loom is 12v Batt on a 20amp fuse... metal fuel rail, hemi tap, becomes hemi torch.

Naturally you get stuck with some of the toughest problems, cuz if it was easy, people would fix it themselves. Thanks for sticking with this one, Wes.

You know. Most people would just write issues like this off and just give up. Pay for wildly and outrageously overpriced new parts and harnesses. You’re a man’s man Wes. Putting up with it to find the issue, that, in all reality minus your time, cost dollars to fix.

You are 100% correct the dealer always replaces parts and then makes repairs if the new parts does not fix it. You saved him lots and maybe even the truck.

When you start to see your truck on Watch Wes Work ... you know it is time to buy a new truck. I hope you feel better sir.

I think i can safely say this ... We would NEVER bail on you Wes... No matter How hard it gets we will Stick with you throughout and do our best to Help You along the way . Although i cant help ya im an i.t guy but im here to Learn from the best :) Cheers mate .

Scotty was right. " The more complex the plumbing the easier it is to stop up the drain"

Wes, this one was epic. Intermittent electrical issues are the hardest and almost impossible to track down. You may have wanted to blow it to bits a few times but you stuck to it and did not resort to the parts canon. I would think an accel pedal sensor(s) plus a computer would have been easy to justify based on what was seen. Keep up the fantastic work.

Nice to hear the shout out's and acknowledgments to the other you tubers that helped or contributed to this complicated diagnosis. Wes is right dealer would have replaced thousands of dollars in parts and still not have fixed the problem.

The most often used phrase I have heard regarding electrical problems in my career is "It must have a short in it." Universal catch all comment. Heard it from customers, mechanics, managers etc. Sometimes that has been used to convey the idea that it can't be diagnosed, or it can't be fixed. Along comes Wes to really study the nature of the "short" and pick out identifying clues and details that blow away the camouflage and "There you are you little troublemaker"!!! Well done Wes!

I have watched this twice and will probably go for a third. At 83+ we had never heard of computers when I was being trained. I found this absolutely fascinating and it is so pleasing to learn new stuff - from someone 45 years younger! Well done , great job.

Wes when I was a younger man working at a friends shop he always told me that anyone can fix the easy stuff but when those types give up and take the problem to guys like you and him that take the next step diagnose before throwing parts at it , we saw lots of cars and trucks come in with lots of new parts , the parts throwers had thrown at it …literally hundreds of dollars of new parts and the same issues they had before all their check book had been spent . Barry would actually diagnose and confirm the problem with lots of times very little more spent . Thanks for being Barry .👍👍

Your skills never cease ro amaze me. Wish you were close enough to be my mechanic

Wes is like the Sherlock Holmes of electrical mystery. "When you have eliminated the impossible, whatever remains, however improbable, must be the truth?" 2 wires shorting against plastic, however improbable, must be cause by moisture, and must be the truth!

Wes I’m amazed at what you have to know and the electronic tools you need. I worked as a licensed mechanic in my own business in the 70’s. My diagnostic tools consisted of my ears, a stethoscope,

As a novice watching I have no problem following along with your explanation of the diagnosis. Keep up the good work you do. Those folks you help I'm certain are singing your praises to those around them.

That was fantastic. Watching an engineer who is also a mechanic troubleshoot some of these issues is .... well, no words. Your combination of an engineering mindset combined with experience as a mechanic allows for some of the most intelligent automotive troubleshooting I think I've seen anywhere. Thanks much, man. I really appreciate you on my Sunday mornings.

Good job. Even back in my day, an intermittent electric problem has always been the bane of a mechanic. In the analog day, you sometimes had to make your best guess.

Awesome job, Wes, similar to a recent SMA episode where the dealer wanted the customer to buy a $2000 harness and Mr. O traced the problem down to a bad alternator. Except in your case a new harness would have fixed the problem.

amazing diagnostic skills Wes. you're right, a dealer would have fired the parts cannon. this is why we watch your channel.

Great fix. Rewarding to figure something difficult like that out and then find the smoking gun. Great work Wes.

Retired wrench 5 years and just went through a reduced engine power situation on my gsons 06 Sierra,multiple U codes and throttle control codes , 2 weeks with my 140.00 amazon scan tool here's what I found, a corroded ground wire to the Under hood modual, u code fix and a flat lined downstream O2 sensor causing a emission concern putting the truck in limp mode, wow I feel your pain, am in salty Michigan as well. Your channel, Eric O.and Diesel Creek are my favorites, always good info.

The absolute best part of this is that you reached out for help with the problem. Nobody knows everything, and we all need help and should help others. Great job in finding and fixing the problem. Thanks for sharing.

If ya' can't reproduce it, ya' can't fix it. A fundamental truth, and it applies to software debugging too (lifelong professional coder here...) Kudos on your persistence and insight.

Thank you for bringing us along on these sorts of frustrating investigations. These sort of videos are where I gain the most insight!

WOW, I am impressed with your diagnostic skills. I was a Avionics Electrician in the Navy back in the 80s and chased wires on F14s and and seen all sorts of crazy stuff that sea water can do to wires. But that was crazy and outstanding work. Great job Wes.

Second comment - the way you got the shot of the wire rub area (back of the compartment, tricky to light, inspection mirror and manual focus) was superb. And putting the relevant diagrams and error codes "on screen" during the video edit must take you a lot of work. Easy for the viewer to take for granted. I am grateful.

Really like the way you stick with it until you find the problem. That kind of perseverance is what makes you stand out. Well done.

In addition to wiring tug tests and such for intermittent issues, maybe we now need to spray water along harnesses and connectors. Great job Wes!

I like these hide-and-seek problem diagnostic videos just as much as your wrench cranking videos. I'm just sorry you had to go through all the headaches.

Gotta love it when the invoice reads parts 5$, labor $500. Just got through a simple brake job that turned into a whole front end rebuild.

WES, Ya lost me at APP1, ! At 67 years old, I learned points And condensers , leaded gas carburetors and manual transmissions from... Motor Manuals! YOU my friend are at a different level with mechanical abilities! Computers in vehicles and Computer diagnostics! Hats off to you! I can't fix this stuff, nor even want to try! Good stuff!!!

That was an incredibly interesting video. I would never have figured that out in a month of Sundays. That customer did well to find you!

"Intermittent" is a dirty word in the repair world. Good work Wes

Another excellent diagnosis Wes. I always learn something from your videos. Invoice: 2 butt splices $1 Knowing where to put butt splices $499 😉

Your deductive reasoning(?) is beyond me. I would have never figured it out. Mostly because you're a genius and I'm an old school freak wishing for more knowledge. Thanks for taking the time to teach us.

Wes, your dedication to this repair is incredible. Don't ever give up, there is always some logic behind the problems!

Love the tech stuff, I could continue to listen to you hours long. Love the videos.

wow !! Fixed the old chevy truck carb and still find a needle in a haystack and know what caused the sensor differences in app1 and app2. No one could have done any more for such a hard to find problem. I'm glad someone is happier finding the problem instead of just throwing parts until its too late. Being able to diagnose these type of problems enables your "fix it" power to be about the best around. Keep it up , and don't let those corp people tell you different

nicely done. Crysler products used to be noted for not starting when wet. They used to say a dog could pee on the wheel and they wouldn't start. Good vid.

Every new vehicle confirms to me just how superior old school mechanical systems are.

Props to you for having great patience and restraint to not deploy the parts cannon on that truck. So many people immediately fire the cannon at issues like this and say it's "fixed". Only to end up with the same problem down the road.

Dude, that is some ninja level diagnosing there. If the customer complains about that very reasonable charge, fire the customer because he doesn't deserve to be able to come back. Outstanding work there, Wes!

I have been an electronics guy all my life (and I am old) and consider myself to be an excellent trouble shooter. What impressed me most about your skillset is not once did I hear a mistake in any terminology or the logic you used during this entire video. That is incredibly rare even among skilled electronics techs.

Hang in there Wes, don't let it kick your ass. It's bound to happen from time to time. Keep the videos coming.

Much respect. My father who started as mechanic in the 1950's, hated electrics with a passion, when there were only a few wires and the most complex part fitted was either the voltage regulator or the dynamo. I'll get him to watch this with me soon and I'll add what his reaction is.

Mind blowing the things modern vehicles need to operate. I love me some intermittent can bus problems on the heavy equipment. Might spend 2 days trying to replicate a problem and still never have it happen.

My father was a computer systems engineer for IBM from 1961 thru 1991. He frequently stated that it is WAY more desirable to be lucky than good when it comes to intermittent problems! ;)

Tenacity, experience and a mental attitude that will not be beaten. Thanks for taking us on the journey. Customer lucky to have you onboard.

Great job Wes. Like the old man said in the movie "Little Big Man", You must endeavor to persevere. That is what you did.

It's these kind of videos I learn the most from. Diagnosing tricky problems like this is a real art and not something everyone can do - firing the parts cannon and turning wrenches is pretty easy by comparison. Less satisfying to watch maybe, but no less valuable especially to your customers.

this is the kinda stuff that separates a good mechanic from a GREAT mechanic. fantastic as always man.

Man you are good! that was very interesting..Humidity does weird things, I had Fax machine years ago that would 'ding' the outside phone bell whenever it rained or was foggy..turns out a spider had got in and died with its legs accross the phone wire terminals and in damp weather dead spider became conductive lmao .. Great chanel Wes.Thanks for sharing your pain with these jobs.

Love seeing these kinds of videos. Troubleshooting and diagnosis is a skill we share and I love seeing how the pros do it. It gives me ideas for how I can improve my own processes when working on problems.

im so incredibly grateful for posting these hard diags, i get the knowledge without the night mare. if i ever stumble into you, i owe you a beer wes!

I watch several channels similar to this one, most of the viewers here probably do also. This is probably the best diagnosis with a scope video I've seen, ever. There's other great ones, but this one is outstanding.

Outstanding job, the fact you’re willing to ask for advice shows how good you are. You also asked Eric who I was thinking about when the video was just starting. He thinks he’s not that smart, he’s just plain wrong. 😉 He has such wonderful skills at narrowing things down. You taught us all some new here too. Your price seems plenty fair as you eliminated many parts and extra hours of labor so for the customer it’s a huge win!

Wow, Wes, just WOW! Man you are incredible. 🤟

An old mechanic friend once told me that the definition of Dodge is “to avoid.” I own a couple and have chased electric issues all over my fathers Town and Country. Great diagnostic work!

That's actually pretty common but none the less your diag was spot on and for 5 hours worth of time that is money well spent. He got an honest diagnosis and not one part cannon was fired. Great job!

Incredible detective work Wes. Moisture makes the most sense because after the moisture evaps due to heat the problem would go away and explains the intermittent issue.

That was pretty awesome to watch Wes. I compliment your dedication and I’m impressed.

I have one of these trucks and I am immediately going out and inspecting that wire harness!!!!!

Wes, in diagnosis, time is never wasted, it is invested, there is always something gained to be used later.

wooow... i wish my mechanics were even able to hook up a lab scope in addition to a OBD interface... huge respect

Your videos are super informative. I did an apprenticeship as a mechanic in the late 70’s, I would be lost trying to diagnose modern vehicle electronics. Keep up the great work, Wes.

Your patience, logic, fault finding and electronic talents are amazing

You are smart enough to know that each problem must be looked out from all angles and then the proper problems be dealt with. You sir do not load a parts cannon, fire it, charge a ton of money and ship it. No your integrity and humbleness to search for answers from others is loud and clear. This is why people trust you and respect you. Thank you for the lessons in fixing things and the lessons in honesty and integrity. We appreciate you. And your respect and acknowledgment to everyone who helped you is exactly what I am talking about. Have a great Easter.

With everything I've seen you do, you're more than fair on the pricing. Anybody that would do these crazy difficult jobs for less isn't likely to do a very good job. The dealer or a shop with an aloof attitude would have charged thousands and thrown a bunch of un-necessary parts at it. And it still might no be fixed. You do thorough work and when it's done, it's done right.

I love these scope/extremely difficult electrical videos. I’ll admit, electrical problems are not my forte, and I’ve given up on a few of them. Great job as always. You fix some nearly impossible problems.

Wes there must be something special in your DNA that needs to be analyzed!

Wes you are the Colombo of mechanics. Always figure out who the bad guy is in the end.

man, your diagnosis skills amaze me. wow. just, wow.

Great job Wes! Incredible problem solving skills.

It is always good to see someone figure out the real problem and not just not throw parts at it, hoping something fixes the problem.

I have had a high admiration for your diagnostic skills but I believe this one takes the cake.

Amazing work Wes. You have a real talent. Well done mate.

Wes, you are God damn BRILLIANT! I hope I will eventually be even a fraction of the diagnostic genius that you are, but I’m not sure I’ll ever be that good!

Wes is like a terrier, biting into the problem, shaking it until cames apart! :-D Thx for showing! :-D

Goddamn this is the most satisfying channel on YT. I felt physical relief when he showed that rubbed through white/brown stripe. I pray I can find a dude like this in NW FL

Hey Wes, love the variety of your content. i dont ind the more technical "looking at computer screen" type of videos Not to mention your sketches and hand drawn schematics are top shelf even though a bit "SKETCHY" lol keep it coming!!!

Dear wess you absolutely kick ass!! Your troubleshooting skills are on a whole another level that I've never seen myself. As always another great video by The Almighty diagnostic King.

Bail??? Who's gonna bail?? Like it or not Wes, you're stuck with us. Great bit of detective work there. If the floor ever drops out of mechanics, you can always get a job working for the Police as an investigator 😁🤣😂Oh, and get well soon Wes 😊

Very nice job Wes. Electrical diag can be time consuming and frustrating but when you find the problem its SOOO satisfying.

Wow man. Impressive diagnostic skills. I need to get me one of those scan tools.

That was impressive detective work. Great job.

WOW!!! FANTASTIC DIAGNOSIS! So many places would have not duplicated the issue, loaded / fired the parts cannon for a new gas pedal and computer, billed the customer $1,000 plus, and the problem would still be there... VERY NICE.

Am enjoying this channel immensely. You and Eric O are my favorites to watch and enjoy. I do enjoy others, but personalities and sense of humor really add to the experience. thank you for sharing your time Wes.

I love these deep dive investigation videos.

Good info on the redundant systems for pedal, nice find on the chaffed wires. Another truck out the door!

After watching you for years I can say you get a lot of those oddball problems. You do one hell of a job diagnosing love to watch

Brilliant work! The number of people who could have ever figured out that diagnosis has to be fairly small. Wow.

The NAG1 transmission in my Jeep was going into limp mode whenever the Jeep got moist. I eventually had to test all of the wires in the harness and run an overlay between the TCM & Transmission. It was a frustrating but rewarding fix...still works 5 years later. It takes about 15 minutes to reset the codes and took a month to sort it out so lots of time sitting on the side of the road doing resets.

As always Wes mind boggling

Eric O is very proud of you. And remember, if He can do it, you can do it.....

You are the man Wes. I think you and SMA need to open an online school and train mechanics all over the country in proper diagnostics.
