In this video I have a look at a 2013 Chevy 3500 Duramax. The customer complaint is that it keeps blowing the cooling fan fuse. Pretty easy right!? Well in this case it was. -Enjoy!

    I'm having an issue on my LML 3500HD. Got a 400 miles to 65mph max with full DEF tank. Peeking around the stable and found a major wire harness from the ECU laying on the EGR housing. Not the greatest at wire issues but hopefully mines will be this simple also fingers crossed!

    Good job as always Eric….

    One sign of a lazy mechanic

    Customer: the fuse keeps blowing

    Lazy mechanic: nothings wrong. Just keep replacing the fuse. It’s normal

    How you can improve rising edge of clutch coil current to rise more sharply to give more realistic duty cycle?

    Experience wins again! Amazing

    A good visual inspection can reveal a multitude of "sins."

  14. Avataaar/Circle Created with python_avatars Andrew ROBINSON says:

    Hard to get a honest opinion. Hench i shall ask you. I am having a issue with my pajero i0 2002 it will not go into low 4wd. I am after getting a cheap /good diagnostic scanner but have been told many different things. Is it a mutt2 scanner i need. Regards Andy Australia.

  15. Avataaar/Circle Created with python_avatars WouterB76 says:

    I guess you could say that Eric is not a big fan of diesel engines.
    Displaying the great diagnosing skills as usual!

  16. Avataaar/Circle Created with python_avatars Doug Kubash says:

  18. Avataaar/Circle Created with python_avatars Shane Harrison says:

    Lol well they weren't squirrel enough bro that's why the dealership couldnt find it but you have the bloodhound to seek it out and squirrel enough to find that nut and mechanic enough to take it on

  19. Avataaar/Circle Created with python_avatars Dave Campbell says:

    Wow thats like a 5 hour drive one way

  20. Avataaar/Circle Created with python_avatars Rick Deckard says:

    Drs. And lawyers pay 125%surcharge.

  21. Avataaar/Circle Created with python_avatars J.O.A.T says:

    The other shop probably wanted to throw parts at it instead of diagnose it. Way to go Eric.

  22. Avataaar/Circle Created with python_avatars Andy Citarella says:

    These are by far the best car videos out there. This guy is so down to earth. He really shows you what it takes to repair something. Not a parts changer. Funny guy too

  23. Avataaar/Circle Created with python_avatars daddyphatsax304 says:

    Framing you F…..

  25. Avataaar/Circle Created with python_avatars Hola! David Hill says:

    A laser pointer would be helpful to see what you’re trying to point out.

    The “Magic Hands” working their magic again. I’d like to know the backstory why there’s some thumbs down. Ps. This comment is mostly for the algorithm.

  28. Avataaar/Circle Created with python_avatars Cory Lenihan says:

    well done

  29. Avataaar/Circle Created with python_avatars Kevin Shea says:

    If I can watch you I can do it

  30. Avataaar/Circle Created with python_avatars Kevin Haddock says:

    This sounds like the kind of problem there would be a TSB for

  31. Avataaar/Circle Created with python_avatars Shane Harrison says:

    Awesome seek and repair video I didnt see anytime wrong with the video or the repair

  32. Avataaar/Circle Created with python_avatars Scott B says:

    One man's anatomy text book is another man's wiring diagram. You might be surprised to learn how close your approach to diagnosis is to a good medical practitioner. History, physical exam, appropriate diagnostic tests, diagnosis, treatment. Your focus on how to approach problems is very helpful.

  33. Avataaar/Circle Created with python_avatars Nick Mitton says:

    Really enjoying your videos Mr O. 😎👍

  34. Avataaar/Circle Created with python_avatars John Vanlandingham says:

    you said whats wrong with this video, perhaps cheap cameras on Amazon? maybe a sony HD camera. I think the focus issues would go away, if not greatly improved?

  35. Avataaar/Circle Created with python_avatars Tom Gep says:

    Another winning performance!

  36. Avataaar/Circle Created with python_avatars curtis stewart says:

    On your Pico is that pulse width modulation?

  37. Avataaar/Circle Created with python_avatars Rip1202 says:

    Great job !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! your the best

  38. Avataaar/Circle Created with python_avatars Lone Wolf says:

    your camera is voice activated just like AvEs?

  39. Avataaar/Circle Created with python_avatars James Tobler says:

    How much you charge for that?

  40. Avataaar/Circle Created with python_avatars Midstate Const says:

    Nice job! I do a ton of electrical diag and repair and must say yes every once in a while you find it quick like that. But not always. Keep up the good work.

  41. Avataaar/Circle Created with python_avatars PastBlast says:

    Normally diagnosis seems to be the big challenge and then the fix is relatively quick. Seems it goes the other way around some times. Great video! Thanks for helping us learn to use our deductive reasoning and not to just shotgun parts at it.

  42. Avataaar/Circle Created with python_avatars 4x4Scout says:

    I know I thought about driving out from WA state to have you diagnose a car. lol

  43. Avataaar/Circle Created with python_avatars Christopher Barnes says:

    Did you use the liquid electrical tape on the bare wire spots in this repair just curious i started using that from seeing you use it in your videos.

  44. Avataaar/Circle Created with python_avatars jorge fernandez says:

    You make all the sense in the world with your approach. Great find. Those kinds of troubles you will never find unless you do it your way. Word is getting out how good you are. Let Mrs O run a bed and breakfast joint for all the out of towner's coming in to get their cars fixed right by you.

  45. Avataaar/Circle Created with python_avatars D N says:

    Seriously I'm just going to hop in my car today and drive 1,178 miles to Eric O's shop in New York so my rusting 04 Tahoe can be on his channel. Some peeps I tell ya…. Lol…. @Eric you're a friggen man to be worshipped !! I'm going to be just like you in my next life…. Lol… Keep em coming…. 👍🤙👍🤙👍🤙🤙🤙🤙

  46. Avataaar/Circle Created with python_avatars F Ober says:

    hello Mr O, I have been watching your videos for some time now and find them informative and entertaining. I have a question for you. I have a 2013 corolla and I am thinking of draining the Antifreeze. I have a new bottle of the stuff but it has been sitting around for 3 years, something like that, and was wondering if it is still good to use. I am not going to flush the whole system and was also wondering if just draining the radiator is ok or should I drain the engine block as well? thank you for you input.

  47. Avataaar/Circle Created with python_avatars Bill delete says:

    Great video checked what could be wrong then started to look for an intermittent situations which includes wire movement. Good job!

  48. Avataaar/Circle Created with python_avatars Ivan Olsen says:
