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!

Well done
From tech to tech. Good diagnosis. Most people would be lost. Or throw parts at it or look for a broken wire, short to ground ect ect.
I swear you hit it right on the head I was just asking where can I get those pliers thank u bro
They are called kiwi pliers because they resemble a kiwi bird.
This is exactly what my 2007 Snotta is doing…and of course it chose to do it during the summer. time to break out the ohm meter.
There website is awsome
Hi Eric I have dodge caravan and the radiator fan fuse keep popping any idea to help out
Just FYI, but others have mentioned the time-current characteristics, but if you Google "littelfuse automotive fuse information" and then click in the mini fuse entry and then on the datasheet, you can see the time-current characteristics. At 135% (13.5A on a 10A fuse) the minimum time to open is 0.75 seconds, and the maximum is 120 seconds (2 minutes). As has been said, this is common operation for these fuses. Circuit breakers have similar time-current characteristics. (I just used 12 Volt for the calculation above for convenience)
Mines blown at start the car
I dinna see boy flinch when hand was raised for beating. Child is too brave and will grow up and go off to war unafraid. HAHAHA I hope not
That mean AC compressor fail. Time for new unit
A perfect example of why you should never increase the size of a factory fuse
Looks like 31 people got busted knuckles installing the belt🙊😂😂😂
Had same problem on a Chevy uplander. Turns out it was antifreeze from a water pump leak that got in the connection.
Thanks for the video 👍🏻👍🏻👍🏻
If someone was really good with electronics could he rebuild the field coil in theory?
Eric you need to get out of NY more off. The are called Kiwi pliers because the look like the wingless bird of NewZealand. Cheers Bob
Great information
Thankyou Eric to show this.thanyou much.
Great job again like always
Hyundai sonata ac problem
for the backyard mechanics without all this fancy equipment just unplug compressor if fuse dont pop boom then u know the compressor has grounded out
I know workshops that would change the 10A fuse for a 15A one, job done… 😢
"That's a really good 10A fuse."
Or a really BAD one!
To comment on your theory of rpm of compressor clutch..I recently had a Cadillac Escalade that was tripping AC fuse same way. After the vehicle was at operating temperature it would start tripping the compressor fuse. Coincidentally the vehicle was erratically displaying "charging system alerts" on the dash. Never had voltage or battery problems though. To isolate the AC circuit issue from the "Dash" message I hard wired the compressor with an inline fuse. I found the compressor would run and make cold air all the way thru operating temperature, however once at operating temperature if we raised the rpm of the engine and got the compressor to a certain pressure and speed it would then trip the fuse. It would idle indefinitely and keep power but once to that raised rpm and making a specific psi on the gauge it would trip on demand every time. This led me to believe that speed of the coil does influence resistance of the circuit. In contrast to what you were saying.
Great work ..thank you very much
Eric, this video is "de ja vú" See your May 14, 2017 video, Hyundai Sonata – No A/C Clutch Operation
Very hopeful thank you!!
If a 10A fuse allows 13.5A to go through – that's not a "really good 10A fuse", that's a really BAD 10A fuse because it will save itself and fry whatever it was supposed to say.
i’m having the same issue with my 2010 p7b crown victoria..as you mention it can go days with a fuse being blown or an hour later and some time the fuse blow soon as i turn the ac on..the fuse also blow while on defrost…once before i put the car into gear and the fuse blew and the ignition fuse blew also… ( the fuse is a 10a label AC MODE SWITCH) i have put a 15a-20a fuse in and blown both…i have had people say it’s an electrical short and even the blower motor resistor…
WILDMAN!
Lol @ hee-yun-day
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
Hi Eric, I had occasion to do exactly as this video last week, I know I am retired but I cant help sticking my nose in sometimes, this one blew a/c fuses without the engine running, the funny thing is I think they fitted two Patten pumps and it done the same….I said well has anyone measured the resistance of the clutch winding…..no lol, I measured it and in both cases it was 0.9 to 1 ohm, practically a dead short, so as you did I reasoned out by ohms law it was drawing about 12 to 15 amps through a 10 amp fuse, so it blew, you cant break the laws of physics Eric, I think they got over it by putting one on that had about 3ohms resistance…cheers great video yet again…from Fred in England.
Somebody in NZ needs to send Eric a kiwi bird souvenir….lol.
The reason that kiwi pliers are named kiwi is because they look like the head and beak if the kiwi bird
My car is doing the exact thing, now it wont blow at all and blowing a/c con fuse everytime we turn the nob for ac or heater
They're called kiwi pliers because they look like kiwis search it up
Great vid. Even I could understand it, mostly. Don't know who that handsome young man was standing there beside you, but considering he looks just like Mrs. O (thank God for that, eh Eric) I'd guess he is one of yours. God Bless.
Keep immediately blowing my interior ACon fuse on my 2006 Hyundai Tucson. Disconnected the ac control, still popped the fuse. Disconnected AC compressor electrical connection, still popped. Even though its interior fuse, would it still pop if it’s bad ground in engine bay?
probably didn't have any grey hair until you got married and had kids. probably asked God for patients so he gave you a family.
If I'm every near Avoca, NY and have a problem AAA is pulling me there.
Couldn't you have just put a 15a fuse in it? I mean, obviously that isn't the "correct" way to do it, but if a person is broke and still wanted to be cool?
The obvious solution here is to install a 15Amp fuse
current is expressed as "I" not "A"
sorry.
Great Video. The A/C is up and running! Beware of offshore 10 amp fuses! My old Fluke 87 has a 10 amp max current measurement, has an EXPENSIVE 15 Amp slow blow fuse. Use an inline 10 amp fuse in its own holder with plug in ends. Better to blow a regular 10 amp mini fuse than an EXPENSIVE 15 Amp slo blow fuse AND the meter!
You sure start those apprentices young!
Fuses aren't magic- a typical 10A ATO fuse might pass a 200% current (20A) for 20 seconds to 2 or more minutes and still be within specs. Different fuse makers use different test criteria. Point being that it will not necessarily blow at exactly 10A. There are differences in quality- buy from name brand companies if you need certainty.
Eric reminds me of the PBS artist Bob Ross
