2011 Hyundai Sonata A/C not cooling diagnosis. - EGM Diagnosis #4 

Tip and trick: I have a 2012 sonata, and I don't put my sonata in drive during the summer, I go all the way down and shift the gears manually, I let the RPM's climb to 4000 and hold for a few seconds before shifting into 2nd, and repeat 4000 RPM's before going into 3rd. I don't shift past 3rd gear unless I get on the highway and it will keep your AC blowing cold. I've been doing this for 3 summers, and I've been searching for a real solution to this problem. Everyone on this feed is having the same problem. We should file another class action lawsuit against Hyundai. They really know how to suck money out of honest people.

I like the way you explain things.

What do you do with the recovered freon from the a/c system????? Is there a recycling center for this. Where????

Educated Grease Monkey, I got a 2013 Sonata 2.0T and wanted to know if the A/C shrader valve is the typical R134a core or JRA type? I got a leaky valve core and wanted to get the correct tool and part. Appreciate your help.

you right and Hyundai sonata AC compressor is weak mine is 2011 Sonata limited while driving is cold but as soon stop on the red light AC start getting little warm mean the compressor is going bad .

Awesome video

How much do you charge for this? I’m also in South Florida looking for a mechanic. My ac started blowing hot after putting Freon in it.

great video

Freon is not going into my AC pressure pipe but got clogged on the wrong pressure pipe. What is your recommended solution

I replaced, expansion valve compressor high pressure switch and office tube. This trash still blows hot after 20 or 30 min. I do notice when I disconnect the battery and connected after 5 min it resets and starts to cool. But only for another 30 min.

That is a clutchless compressor just because it’s turning doesn’t mean it’s engaged. The ECV has to be activated.

The ac control valve could also be the problem, they are sold sepertly and could save you money. The valve is located on the ac compressor it self.

Thank you for this. It's pretty much what I suspected but this just confirms it.

What about checking the fuses and relays for the ac ?

since your in Miami? how much do you charge to change out a compressor? I'm in Miami too

Did u replace it?? What kind of price tag job would that be?? My sonata failing also.

Will this work on a 2016 Sonata?

i had this problem for about 2 months the ac would work but all of a sudden it would blow hot air they check the freon it was topped off so they told me to clean the part that looks like the radiator i did that it worked for about a minute but what i noticed was when i hosed that lil radiator part the ac worked fine until the engine got to high temperature the radiator was topped of with antifreeze didnt need adding also the fans were working so the only thing i suspected was the car was getting somewhat hot because the catalytic converter was clogged went to a shop they swapped it out with another one as soon as i drove off from the muffler shop i noticed the ac blowing cold air again before you start spending money on ac parts check for a clogged catalytic converter first mine had 144000 miles maybe your asking what does the converter have to do with the ac well if the cnverter is clogged its not passing the hot air towards the tail pipe and the engine gets hot if the radiator isnt cooling right the ac wont blow cold hope this helps it sho did to me

I have same problems with my sonata 2013,any recommendations how I can fix,or any ideas what’s the problems ,thanks

I have same car - my a/c takes forever to blow cold ...then once it blows cold - it blows warm again ...any answers??? Thanks

I have a 2011 hyundai sonata limited, The AC blows hot air sometimes when the outside temp ~95F. it seems like the AC works intermittently. it seems like the compressor is just quitting sometimes. I checked the low side AC pipes and it is warm when the AC is not cooling. Do you think it is the compressor or anything electrical related?

Question, I have 2012 Sonata blows hot air! the freon is full and it still doesn't run I don't hear the compressor to be working. I checked the fuses as well and they seem to be fine any suggestions ?

If the expansion valve is trash it usually goes into vacuum on the gauge

hello carlos i am watchen you from saudi aribia and we have hot summer maybe 50° or more and i have sonata 2011 i chenge evre thing the comprisor and air filter and thermostat and the radeter but stell just hot air when i stop that ploblem i have it from 5 yaers without anser can you help me for slution !

Same problem on my wife's 2011 Sonata. Dammit Man those compressors are expensive.

my AC works going down the rd. but not when sitting still. what is wrong.

Mines cools whenever he wants

hi there thanks for the video i have an issue with ac so the thing is in summer when i opened the ac the cold air goes only from driver's vent and the passengers vent comes a hot air i charged with gas it's back to normal then after 2 days its coming back again this issue now we are in winter the driver's vent blowing hot air (switch to hot ) and the passenger's vent blowing cold air whats is the problem ?? i live outside usa my car is hyundai sonata 2011

When i drive around for sometime, it would cool. But now mine is staying warm after when I expect it to be cool. Is that a freon issue, you think? I think my compressor needs looked at cuz your demonstration is how mine is acting.

You never said what you did to fix the sonata . You said could be 3 things then your on the gas an it's fix

Don't know if this is an old wives tale but I have been in the habit of turning off my air-con about 2 minutes from my destination with the fan running till it's blowing warm. My 2011 Sonata has 170k and air is still running pretty good here in Florida. Hope it helps.

So I live in hot Florida as well, my dashboard actually just cracked a couple months ago. I’ve been struggling to figure out my A/C issue, it only blows cool air when it’s raining or if it’s night. I’m also a woman who knows little to nothing about cars so watching this video really confused me and idk what to do, just tired of sweating in my car

Hi Carlos love your videos. do yoy think once you repair the ac concern you can put a thermometer so we can actually see the temperature. thank you very muc.

32k ON IT. TODAY MY A/C WORKED REALLY COLD FOR ABOUT 40 MINS (LOCAL TRAFFIC STOP AND 50 MPH AT TIMES) UNTIL I GOT CLOSER TO HOME AND GOING ABOUT 20-30 MPH. ALL OF A SUDDEN THE AIR COMING OUT WAS NOT COLD -ANYMORE BUT ROOM TEMP, NOT WARM. THIS HAPPENED ONCE BEFORE THE EXACT SAME SCENARIO. HOW CAN I TRUST I WILL NOT BE TOLD ITS THE COMPRESSOR OR CONDENSER ($$$$$) WHEN ITS SOMETHING MUCH LESS EXPENSIVE TO FIX?

Mine blows hot on drivers side a cold on passenger

Low 20-40 High 150-200 max If higher then expansion valve blocked by ice( moisture in sys)

Where can I get the same rims?

Awww man... When I did my search, I was hoping to find how to properly charge the freon in my 2011 Sonata 2.0T, thinking a recharge would do the trick. What do I find instead? A whole bunch of other Hyundai owners going through yet another frustrating issue with their Sonatas. Smh. I'm so f**kin' tired of Hyundai by now... It's hot as ballz, and I'm having the same problems with my AC... intermittent cooling for weeks, now I get up to go to work this morning and have NO AC at all. I'm not even gonna finish watching this video as, judging by the comments, it offers no solution. Thanks for trying, though.

The A/C in my Hyundai Santa Fe 2008 was blowing hot so I recharged the system. During the recharge the compressor kicked on and the A/C started blowing cold. But I noticed a light continuous smoking coming out of the grill area where the charging ports are located. The car blew cold the rest of the day in 92 degree weather but the next day it only blew hot again. What is going on with it?

Are you still a mechanic in miami, I’d love to connect.

You gave no answer here if you replacing everything you never figured out what exactly was the problem

I have same issues with my sonata 2012.

The headlights on this model are trash too. I replaced them with LED's and nothing.

H OW MUCH WOULD ALL THAT COST IF YOU GO TO A MECHANIC? i UNDERSTAND THAT THE COMPRESSOR IS HARD TO GET TO?

He doesn't mention to CHECK YOUR A/C FUSE FIRST. You could end up spending a lot of money replacing a compressor when it could have been your air conditioning fuse. A couple of bucks vs. nearly a thousand to fix. Cool video though.

Are you in a hurricane?

Bad diag, that compressor has no clutch... Problem is the ECV, a bad expansion valve or compressor would show you on gauges.

umm wtf... I have a 2012 GLS and it is NOT push to start, nor does it have a big ass display. I feel scammed ): is this a different version? Like the limited or something?

my red knob broke off my AC tester from Harbor Freight as well. UGH

Same issue here with my 2011 hyundia sonata I see this is a very common issue with sonatas smh 🤦🏿‍♂️

Why don't you buy a German car or a Japanese car? It's strange…

How the heck do you expect us to hear anything your're saying with all that super loud background engine noise!

Sorry, those wheels are hideous. Why do people waste money on that crap??????????????????????????????????????
