Nice job Glen finding the leak. Like you said, I have gone to hydraulic shops for hose repair too. Thanks and take care

Nice work and I enjoyed the information you shared about the system.

I've had issues with hoses before. Good work.

Awesome video man. Thanks and keep up the good work. I appreciate the troubleshooting steps.

Great work Glen! Just a few tips I picked up over the years. I always use blue Nylog on o’rings as it seals and lubricates although the refrigerant oil is fine too. Fill the system with nitrogen at 200 psi and use ultrasonics as it’s a great way to find even very small leaks. And I always hate leaks especially the one where the entire system is empty. It’s a guessing game of how much oil to put back into the system. Have a great evening! 😀👍

Great summary and good find! It always surprises me how often one can fix problems, with a little common sense. There are many videos here on RU-vid, some by professionals, explaining how to do AC repairs wrong. The most common errors are to put compressed air into the system, and inadequate vacuum after the system is cleared. Both allow water into the system, which slowly messes things up by freezing and thawing water in the wrong place, caused by the normal huge swings of pressure.

Very well explained with lots of detail Enjoyed the video Thanks for sharing

Great job Glen

I'm glad I'm not the only one who talks to hardware. Nice when it works (like the 10mm hex that didn't fall) because you seem less bonkers that way ;)

This video was exactly what I was looking for. My 2013 Santa Fe had the same issue. I have worked on my own cars for 45 years and this is the first time that I have had an air conditioner issue on one of my cars. The oil leak on the hose was not obvious and I thought it was just road grime. Even with fluorescent dye, it wasn't really obvious. However, the oil/dirt was on the hose and I replaced it. Mine has the 2.0 Turbo, so the hose is a little different. It was not very hard to start the nut back. I would strongly suggest, since it was something that I didn't do, is to spray the connection at the compressor with cleaner or compressed air. Dumb move on my part, but I was thinking about the rest of the job. When I pulled the hose out of the compressor, mine had a some "gunky" stuff fall on the floor. Took me a bit longer to ensure that none had fallen into the port. CLEAN THE CONNECTION before removing the hose. I also used orange thread locker on the upper and lower nuts when I put them back on. Ran a vacuum for 1 hour and then closed up the system and still had -28 psi on the closed system 45 minutes later. Charged it up and system was putting out 44.5 degree air with outside air @ 92 degrees. Thank you for the time that you spent making the video. Saved me a lot of time!

Nicely done Glen ✔

Thank you for clarifying that it didn’t even need a single dugga

I do a lot of Auto A/C work myself. Great video.

Very helpful.. I have the same car and I got the same problem and just ordered a new discharge line.. Did you add oil to the system after changed the line?

Good job, my friend I have problem on air condition it’s coming high I can’t to make slow. I checked for fuses and still no change for that. I go to many mechanical air they didn’t finde the problem. My car is azera 2016

The AC swith and Air blower in and out is working fine but the problems all the small lights related to these boutms are not lighted and Ac working with out it when I press it.also the passenger window lift side is not working . (SANTAFE 4WD 2015

Thank you for sharing. I have problem with 3rd row AC doesn't work. Can you share idea how to fix it?

That suction line off the compressor was so common on these, along with the Santa fee sport and sonata. I lost count of how many of them I’ve done

Thanks for the vids. I need to recharge my 2014 Hyundai Santa Fe Sport, so I went looking for the connectors. The H connector was right where the video showed it, but the L connector was back on the firewall, not down below the alternator-I was lucky to spot it I only mention this because it suggests a tube of a different shape-people may have to specify that to their jobber Any comment?

Now comes the the fun part of how much oil to put back in.

Thank you for your detailed videos Glen. I am in the middle of doing the same repair and had a quick question. For the lower 10mm bolt, did you remove it while under the car or use a ratchet extension and get it from the top? I'm having a little trouble getting in there and every video I come across skips the actual removal of the line haha

Buddy I have a 2009 Elantra with the same fitting by the high pressure port that I can not get apart like it is seized. Any tips? Heat maybe?

First-time viewer. A few diagnostic steps and info I would have given in the video, you did not seem to raise the idle while sitting in the cabin to see if vent temps would change. When seeing 5 PSI you did not mention what PSI you are expecting at the current ambient temperature. Thanks for the diagnosis and repair on the line. Have you thought to make playlists based on the Manufacturer of the vehicles?

Hi I'm your new subscriber, I would like to ask if it is normal to experience the Lower Pressure line sweating during A/C operating?

Are all r134a low pressure nipples the same size for all makes? Is ford r234a nipple same as Hyundai?

My 2005 hyundai accent does not have a A/C the garage said A/c was not put in 2005,s car,is that true?

Hi, i have a 2010 santa fe. The charge is ok and compressor is spinning. But the air coming out of vent is not cold. I touched the suction line under the hood heading into the evaporator and it's not cold. Can it be a bad expansion valve? Thanks

My AC sometimes blows cold, sometimes blows hot. Any suggestions?

❤❤❤thanks

damn good video! thank you sir

Why don’t people trust aftermarket? My thinking is that if OEM part fails then we know it’s trash, so we definitely don’t want that one again, so why not try a different brand? As their ones could be better… excellent video anyway helped me a lot!

Greetings for u from Iraq

Was this a 2.0 or 2.4 engine?

Its crazy this newer car would have ac issues..

Another method is check the Hyundai part number with Kia. Many of the parts are the same and slightly cheaper.

It blows for 2 hours and then it stops blowing
