    You are # 1 mr Eric ..

  2. Avataaar/Circle Created with python_avatars Julian Perez says:

    Mr Eric you don't think the wiper motor is worn out and the shaft is shorting out when you wigle it ?

  3. Avataaar/Circle Created with python_avatars Julian Perez says:

    What if you disconect the wiper motor mr o ?

  4. Avataaar/Circle Created with python_avatars Julian Perez says:

    I say is a grounds stat with broten wires mr o..

    That was so great how you mapped out the correct path and didn't let the confusion and anomalies lead you to tear apart the cowl or access to the bodywork.
    The electrical problem was originally the A/C fuse and whatever you had now had to relate to the work that was just done before it came to you.
    That new GM wiring is a comedy of material saving and lightweight material in use and alot of plastic.
    It sucks. You can't just depend on anything like previous years were. So methodically, you had to arrive at the grip of the fitment as the cause. Under load a circuit has to carry the current and using less material reduces the surface areas of those multiple pins.
    Just the way they went about assembling could result in the cause. The way you repeated the operation resulted in the correction. It seems.
    The backfeed led to the wiggle test that helped you by the sounds.
    Bizarre was the right term.

    That plug you just plugged in got your good ground you can that plug can be plugged in totally 180° I did that been there cost me $1,000 or figure it out

  7. Avataaar/Circle Created with python_avatars Edward Demedeiros says:

    Wow! The things than can go wrong! Good catch!

  8. Avataaar/Circle Created with python_avatars Greg Smart says:

    Excellent Job in fighting that "floating/rerouted ground path" ;due to, the customer's poor installation of the Fuse Box. You gotta love the weird ones. Thanks for sharing!!!

    I would have checked the lug nuts first thing but I guess that's why you're a better mechanic than me.

    On my Eric O greatest hits list =)

    I chased a parasitic draw on a 2010 cobalt for a year and a half. The dome light bulb was blown and it kept trying to dim the light. Could never find it because door was open while testing. It took a week not driving to run battery dead. Every 15 minutes it would try dimming the light.

  12. Avataaar/Circle Created with python_avatars Charles Smith says:

    What do you charge for something like this?

  13. Avataaar/Circle Created with python_avatars Stardust says:

    My 2005 Cobalt only has 262,000 and still runs/drives great. Great pizza/DoorDash car.

  14. Avataaar/Circle Created with python_avatars Antonio Claudio Michael says:

    Interesting how a tweeked Pin Caused the Problem good Video Eric O @SouthMainAutoRepairLLC

  15. Avataaar/Circle Created with python_avatars First Last says:

    Just remember if Eric can do it you can’t do it that’s why he’s doing it

    The owner of the car was ordered to stay off haunted baby doll island…..they visited it despite the warning///now they're collecting their reward.

  17. Avataaar/Circle Created with python_avatars Chevy Girl says:

    Had the same ground problem it was not the grounds under the fill tank , the problem was the 6 grounds under the radiator hose , they was hard to see even pulling the radiator hose back , this video was helpful in some of the chase though thanks

  18. Avataaar/Circle Created with python_avatars William Morris says:

    Being from a construction background my brain works different . I would approach this from the, what wiring is connected to the cowl, or, what wiring is connected to things attached to that cowl

  19. Avataaar/Circle Created with python_avatars twwtb says:

    Thanks for the info about your wiring diagrams. Mitchell also offers a DIY subscription for a single vehicle which seems pretty reasonable.

  20. Avataaar/Circle Created with python_avatars PROPHESIED says:

    They have a recall on the ignition cylinder and the car can shut off while driving

  21. Avataaar/Circle Created with python_avatars Keith Knight says:

    What about the original issue about the AC which started the whole issue?

  22. Avataaar/Circle Created with python_avatars Darryl Rosswalter says:

    1st video I've seen of yours & hitting the subscribe button. You stay focussed & determined & followed the circuit to the culprit & fixed multiple issues. Hellofa job sir

  23. Avataaar/Circle Created with python_avatars Jon Miner says:

    Hi, Mr. And Mrs. O. I hope you guys are happy and healthy. It is great to see two such charming people banter on their own YouTube channel. OK, Mrs. O is more charming than Mr. O, but that is to be expected. I know this is an old video, but I don't care. Thanks for sharing! Stay Healthy!

  24. Avataaar/Circle Created with python_avatars Ben V says:

    Perplexing problem!

  25. Avataaar/Circle Created with python_avatars Paul Spickernell says:

    Been watching loads of your content, that was one of the best. Wish you were in the uk, had to scrap a merc slk. convertible recently due to electrical issues, no one had a clue, They said moisture in fuse box, engine starts can’t turn off, every light on dash came one at once. Loved that car

  26. Avataaar/Circle Created with python_avatars scotts01Z71 says:

    It could be nothing… my first thought, or it could be everything…lol.

  27. Avataaar/Circle Created with python_avatars Mentology Health Awareness says:

    Wasn’t the cobalt a revamped cavalier? I had a rust box cavalier with a bad gas gauge. Bad oil sensor. And went through 40 rebuilt steering pump (they all leaked). Until I paid for the genuine new part. Hated that car. No power. Nothing. Was my very first car many years ago.

  28. Avataaar/Circle Created with python_avatars Adam Buttner says:

    I know there’s been times where I had to remove those fuse boxes on gm cars to do certain jobs and after putting them back together I’ve had them not start or have other weird issues. Every time the fix was to unplug the box and plug it all back in and they were fine and are still fine. I could never figure out exactly why I had to do it because all the connections were seated right with no bent pins. Those gm boxes are just finicky lol

  29. Avataaar/Circle Created with python_avatars John Dickerson says:

    It's easy to say "Bad Ground". But it takes a good Technician to actually find the bad Ground and repair it. Great job bro.

  30. Avataaar/Circle Created with python_avatars Joshua Hutchins says:

    I was on the edge of my seat, no idea how the problem occurred great video series

  31. Avataaar/Circle Created with python_avatars Robert Grimley says:

    Do you have a multi-meter? When tracing electrical circuits it is an indispensable tool. You had an improperly connected ground connection causing your power circuit to search for a ground. It found a ground through a key on/run power circuit (through the power circuit in the wiper motor). When the cowling was flexed it disrupted the ground of the wiper circuit causing loss of ground to everything. I did electrical diagnosis/repair for years.

  32. Avataaar/Circle Created with python_avatars LeewardStudios says:

    What about the blown AC fuse set to 25 amps? Still no AC? Sorry just my OCD. I wouldn’t trust sending it back to have them smoke another fuse box and blame it on me.

  34. Avataaar/Circle Created with python_avatars john doe says:

    I have one for you 09 cobalt will start fine run 20 minutes won't start set 30 minutes to start up fine?

  35. Avataaar/Circle Created with python_avatars Tyler DeBoy says:

    Casually a WWII Air Warning at the end of the video 😂😂

  36. Avataaar/Circle Created with python_avatars Scott Farris says:

    Yeah, I know I’m late but being an electronic technician I’m wondering how the ground side of the relay made a path to the wiper motor. It had to be shorted to there and it had to be shorted at the fuse box circuit board, through some kind of consecutive debris. When Eric tilted the fuse-box sideways, whatever conductive debris was shorting the traces on the circuit board, fell off.

  37. Avataaar/Circle Created with python_avatars Eduardo Garcia says:

    If watching with the captions on, Everytime a car passes the shop it says [applause], and sometimes at the most hilarious times of the video. Nonetheless, great video Eric! Thank you for posting, I know this video is older, but I watch your channel every chance I get.

  38. Avataaar/Circle Created with python_avatars daniellma says:

    The wiper 'fix' actually was misleading…but an interesting sidetrack. I have seen this several times with other connectors, the bent pin would not allow the connector to fully seat…even thought it was tight
    it was not fully seated…therefore the f2 pin was not making contact.. It used to happen all the time with computer connectors,

  39. Avataaar/Circle Created with python_avatars Tyler Durden says:

    my office is right by a lunchtime alarm too but they let you know its lunchtime and blast it for at least 2 minutes. I hate it every time.

  40. Avataaar/Circle Created with python_avatars josh bishop says:

    You talk about diagnosing and focusing on one problem at a time. I had a writing problem with an 06 Cobalt and I can confirm, considering all the problems as common and finding the cause based on that went nowhere. The solution was to focus on one at a time. There was some hackery in the fuse box I never figured out, but at least I got the car functioning and legal. I hate when someone else has already been into the wiring.

  41. Avataaar/Circle Created with python_avatars SJL8006 says:

    IMHO. I've had trouble with damp fuse boxes. Any time they are apart, I give then a spray with fluid film or the like. Keep it dry, keep the green away
