Hyundai Sonata: Keeps Blowing A/C Fuse

In this video we have a look at a Hyundai Sonata that keeps blowing the "Air Con" fuse in the underhood fuse block. It doesn't take to long to track this one down. -Enjoy!

THANKS A MILLION!!

Kiwi is a bird with a bill that looks similar to the pliers. Thanks for sharing the knowledge! Funny seeing the young fellow with his hair combed like that. It's the same way I combed mine well over 50 years ago. Interesting how styles come full circle.

Another AC repaired by one of the coolest repair guys on the internet.Way to go Eric O!

[ozzstars_cars]

I brought myself here. Excellent explanation Eric on your thought process for a proper diagnosis!

[sharedknowledge]

Sustaining 13 amps for a while on a 10 amp fuse is to be expected. If you're curious look up fuse data sheets from fuse manufactures. They show graphs of overload currents vs time to blow. So what you showed is exactly what I'd expect.

Gavin, Evan, and Trinity all have looks, brains, and heart. Better have that talk with them early and often. Excellent diagnosis and thumbs up video.

[andrewwilson]

I swear you hit it right on the head I was just asking where can I get those pliers thank u bro

[ALZ]

Good diagnosis 26 years HVAC tech love watching your videos.

[wyattoneable]

It's nice when the customer is easy to work with. Love these diag videos.

[garysgarage]

Your videos are best on the web. I do see you get some thumbs down and I am very curious why they don't like your videos. Have they ever left any comments to why they gave you a thumbs down? I can't see anything you could do different to make them better. Thanks Gary

[EldoonNemar]

thank you for drawing on the wire diagram. I have a hard time following you with those, generally. made it much easier.

[davidwilliams]

great call on the a/c compressor i would have drawn the same conclusion myself keep these great videos coming

I had a similar issue with the same type of circuit you diagnosed but it was on a bus of course, lol. Had a TK Intellegaire 1 unit that would blow the clutch fuse after about 5 minutes of operation and just like with yours the coil current would build over time and then blow the fuse. However in my case it was not the coil that was drawing too much current I had a frayed and corroded wire that was touching the frame of the bus and acting like another load in parallel, so when you turned on the circuit it would draw more current and then it would take about 5 minutes to blow the breaker due to the length of the harness. The harness was about 20 ft long, so it took a bit to build the extra heat to blow the breaker. From my experience when you have a short to ground if the fuse blows immediately the problem is close by and if it takes longer the issue is further down stream. Good job Eric.🙂
I also saw your article in Motor Age, very good. You should put some material together and submit to some trade shows and instruct, the industry needs more Techs like you being involved. Have a good day my friend.🙂

I ordered those Kiwi Pliers about 4 hours before i came here. I went on Google and this video came up in a search result for them. Fancy Vantage Pro you got there Eric lol. I'm stuck with a hacked Modis that is behind on updates but just use it for the 4CH scope. But if I really wanna get into any computer I have a pretty neat Autel Tablet...

My man, I am so glad I found your channel. Electrical diagnosis has always been a weak point with me, but the way you go through and explain it makes it seem so simple. Because of my experience I picked the compressor straight away when you said it took some time for the fuse to blow, but looking at the graph and seeing the amperage being that high sort of makes it even clearer in my head of why it is doing it. I will definitely keep watching your channel and hopefully get better at this type of work. I plan on starting my own mobile mechanic business soon and because I specialize in Toyota and Lexus I was a bit hesitant to branch out into all models. Mechanical work comes easy to me but the diag is where I need more practice and training.

[trentputnam]

Love your quality breakdown on every repair you do, really wish every shop had your skills and knowledge... Eric O. for president! Make America's cars great again!

[comingundone]

How does he get thumbs down on his videos. All methods are tested. I love this channel.

[fieldsofomagh]

The labscope comes in handy for a lot of faults and really shines in time v voltage or amps. Job well done.

[Eric_the_Hiking]

Those pliers are called kiwi because they look like a kiwi bird.

[TheShop]

Very educational Eric. This was a great one. You should have your own TV show. Best channel on YouTube.

[HayabusaRydr]

They make several different types of fuses. Some have a buffer built in and some are considered slow blow which is what i used to use in audio competitions back in the day. Just a bit of info i can give you Eric since you give us so much
