- Kia Optima Issue with A/C working and then not working. I do believe it is FIXED finally, and I did it myself. Swapped out the Compressor Control Valve. This specific one I purchased from Amazon and all the tools I needed from Harbor Freight ( the vac pump and AC manifold ).
Thanks a bunch my boyfriend is not a mechanic and I found your video and showed him and he fixed it. Thanks for uploading this video...♥️♥️♥️
Tracy Jackson HECK YEAH! Great to hear! Our AC is still going strong.
Pro tip for anyone trying this at home: rub some PAG oil (or whatever the Optima's compressor is supposed to take) on the o-rings before install. This ensures that the o rings won't get pinched or roll during install. Also makes install a little easier. You can find the correct compressor oil at any part store.
Thanks… as someone who also makes little DIY videos to help others out, I appreciate it! Most of all you proved that you don’t have to take off the compressor which some other videos advised.
Your Welcome! And your right, there was zero reasons to remove the compressor, it was so simple to do it without taking it off. I’ll check out some of your videos.
Thank you for doing this, gave me the confidence to do my own daughter's optima!
It held up and worked for years for me, we just sold my daughters Optima and it was still cold as ice. Your welcome! People help me all the time, the least a person could do is pass it on.
Great video. 2012 Optima ac works great after replacing the compressor control valve. Thanks!
Update: This repair has made all the difference. Air is super cold and has not shut off once!
I need to find the valve. Where did you get yours?

It worked, thanks a bunch, stay safe and God Bless 🙌🏽.
Heck YES! Awesome news! Have a Great Weekend
Thanks for this! I'm having issues with my 2012 Optima's AC and I believe this could be the solution!
I researched and researched, I found several people locally that had the same issues with their 2011/2012 Models and both of them took it to the dealer and they told both of them the compressor had to be changed and it was major $$$$$$! So with that thought, I decided to replace the pressure valve with a newer style that had larger orifice openings within the valve. It's been over a month now and hot as heck and the system is still working perfect. $28 part..... priceless! Good luck!
@@jmaverick wow! thanks a lot. Do you have a link to order the part by chance?
Nvm I see you provided the link in another comment. Thanks again!
J Golden My 2012 will work then stop then seems to start again every 5 minents. is that what yours was doing?
Nick Knepper it did that at first then it was just very random. The blower and all keep working, it was just cold one min and hot the next minute
Thank you so much. I all ready did new fans expansion valve. Hopefully this fixes it
How did you evacuate the refrigerant? Don't u need a vacuum pump
I had a friend pull the refrigerant out and I did use a vac pump to pull vac on the system before I added new refrigerant back. I used a digital scale to measure the correct amount when adding it back.
Those “auto repair guys” on TH-cam that have done a thousand 2013 sonata videos say you have to take the o ring off the new valve and place it in its groove inside the compressor, they even show themselves doing it. Why do you think that is? I know O-rings get stuck behind and you can double up by accident, but your factory one looks like it was actually placed in that groove, which makes me think they were right.
I have no idea why they do that, but you should ALWAYS check your parts you remove to ensure the O-Rings came out with it and put it back just like it came out. I work on hydraulic cylinders and much more that use O-Rings and I stand by the way I did it. Just ensure you never put an O-Ring in dry! Lube it up somehow.
I have same year model car.
The ac issue is the same as you described. The local shops quoted anywhere from $ 800 to $ 2000 to replace compressor.
I will give this a try. Thank you.
Btw is your Kia burning oil as well.
That’s another issue with kia cars manufactured between 2011 to 2015 I believe.
Kyra, I have found out that there is a “recall” for some AC wiring extension, not sure if that is the actual culprit that ends up causing all of that but I would check into it and possibly get Kia to fix it for free. But probably not since most of them just wanna make a quick $$$
Oh, and YES! It’s burning the heck out of the oil. A whole lot of oil. It’s my daughters car and I actually had it in a Kia dealership last week for 2 recalls ( AC wiring recall, and a vapor canister recall ). Anyway, they just said it needs a new engine AGAIN and they just happened to have one. I said no thanks but thanks for trying to scam me. It’s gotta be a known issue with KIA
@@jmaverick
Yep i hear you. You gotta watch these dealerships. They will scam you plus do everything not to stand behind their warranty. Its a shame really. Probably the last time i buy Kia. Never again.
When adding refrigerant do you need to add oil with it for the compressor?
I didn't because I only changed that valve and thus all the oil should still be in the system.
Nice fix! I may give this a try. I've got a 2011 that the AC works well sometimes when driving, but not always. It almost never works when the car is stopped. It's very intermittent, but when it works, it works well. Question... Do you just vent the coolant? When you recharge the system, do you need to add any oil back to it?
That sounds like the problem we were having exactly, although when ours decided to work it would work somewhat when stopped. As far as venting, for the environments sake, your supposed to capture the Freon that's in it, but most people at home doing this don't have the ability to capture it and just let it go. And just replacing this valve doesn't require you to add oil back to the system, the compressor is retaining all the oil it already had. Good luck! And if you do the repair, please come back and post your results!
I strongly suspect I have a bad solenoid valve too but I have no way of confirming for sure. I want to be 100% sure it is the valve and not the compressor. Normally I wouldn't mind wasting $40 for the part but in this case it will be much more than that because I will have to evac/recharge the whole system twice
I have a 2013 with AC problems. It started with not blowing cold enough, so it was pressure tested, then drained and refilled. But since then occasionally it just doesn't blow cold air at all, only warm, no matter if I drive it or not. Then I shut down the engine, restart and hope it works. So far, it happened only 3 times in 4 weeks... Could it be a pressure switch only? Or is it the same as in your video?
Ron Swanson that’s how my issue started, and it sounds as if it’s the same exact problem. I found forums where people reported the same symptoms from years 2011-2014. Most of not all repair shops will want to change out the entire compressor, and I didn’t want to pay multiple hundreds of $$$. Try the fix I did, it’s easy and saves quite a bit of money. The pressure switch is really cheap. Hope this answer helps.
@@jmaverick From what I see you replaced the valve control. Have you tried replacing just the pressure switch before? (977213K000) They say I don't even need to drain the system to be able to replace that so it seems an even easier attempt... But again, I'm no expert in fixing, just expert in researching :)
Ron Swanson I did not replace the switch, just the valve. I don’t remember where I read it, possibly a Kia Optima forum, but I had read where several people tried the switch and did not have success. What I ultimately found was a video or post ( been too long to remember ) and this person who posted had stated that from their opinion the OEM system was built and tested in a climate that didn’t have the extreme humidity present which changes the nature of the system. They had some tech bulletins and other stuff posted as reference material. Log story short, the replacement valve along with the valves that are preloaded in replacement compressors are of a different design and their orifices are slightly larger. I’m not a technician nor an engineer so I took a gamble after all the frustration with a system that works one min and not the next min. And lastly I was tired of paying people to do work like that so I purchased the tools and learned how to do it myself ( for a few $$$ less than paying someone and now I have the tools for future use ).
Having a similar problem where it will work on and off going down highway will blow ice cold but going through town stopping and what not will be hot .. but I noticed clutch on compressor isn’t kicking off when the ac is turned off .. it’s spinning constantly
Carter Juarez . I can’t speak to that issue, I never actually looked at my compressor while the AC was off but the car was running. You may be better off in this situation to seek a professional for help. BUT - as I recently did with an older square body S-10 I have, I found a random person in town one day with a similar truck and just approached them and asked them if I could look under the hood and checked a few things to diagnose my issue. The totally random person was a huge help and never hesitated to help. It’s worth a shot to ask a random person with a similar Optima just to see if their compressor clutch keeps spinning.
J Golden thanks for your input I’ll have to check it out thanks again !!
Sorry if this seems repetitive, but with my 2012 It blows extremely cold at highway speeds but in town/ stop and go traffic the air feels hot/ humid. I can be driving on the highway for about an hour, turn the car off for maybe a minute and then once I start her up itll be so hot, like it had been sitting for hours.
I took it to my Pep boys and they said something about a high hose needing to be replaced? Sorry I forgot the right term but If it was torn wouldn't it just blow hot air all the time? They're asking around $600 , I am nervouse to pay and it be another issue.
Jaime U well that’s very similar to the issue I had, not exactly. But I will say that the part where it does work and you shut the car off and get back on and it’s not working, that’s exactly what my problem was along with many other people that have messaged me. I did ask my daughter since it’s her car, she did say that it wouldn’t work in the drive way but at highway speed it was cold and stayed that way until she turned the car off. BIG CLUE - According to many Kia forums that I found, the issue a lot of people had In common when it came to AC issues was that they lived in very hot and humid places. The replacement valve I used was designed for more flow In hot temps, and I’m just saying that based on the orifice sizes on both sides of the valves and the manufacture specs of other valves for hotter and humid climates. Maybe I’m crazy, but it makes sense when you consider what the AC system does with the air to make it cold.
As far as Pep Boys, I’ve never heard of the high hose being bad and yet the system still works at high speeds. I’m not a certified tech, just a guy that will spend 20hrs reading and learning how to do a 5 min repair just so I know how to do it. The valve don’t cost that much compared to what pep boys wants to charge, maybe it’s worth a shot?!?!? And remember that you can rent the tools you need to vac suck the system down, check pressures and recharge it, just study the method and be careful.
So I finally got to replace the part, and I am relieved to say it works great now!
Thanks a lot for sharing your knowledge with us! We owe you a steak dinner lol
Was it necessary to put negotiate pressures the system to change the sensor or can it just be changed?
You must drain the system for sure. The refrigerant flows through this valve, so it must be relieved of pressure to remove the sensor/valve.
So I went to a shop to get the control valve switched and the one they gave me that they stated was the old one still had the little grey/clear piece sticking out the bottom. And I’m just wondering how would I know if they changed it or not ?
Zahlinr my original and the one I replaced it with looked different for sure. The only way you can know for sure is if you had a picture of the one you purchased to compare it with or if you saw them change it out personally. If you purchased it online, go and see if you can find a picture of it for comparison.
J Golden it looks about the same but my a/c is colder but i don’t know if that’s just because they drained the system and added Freon or because of the piece being changed
Zahlinr I guess time will tell then. My valve I replaced was obviously different, so I knew for sure. Good luck my friend!
Hi by any chance did this being bad affect engine performance?
No it did not
Hey I bought the compressor valve but before I do all this I need to know If that's exactly the right move.
My A/C is not blowing at all
Would this help turn it back on?
David Mena if it’s not blowing at all the. That isn’t the issue. When you say “not blowing at all”, does that mean the blower isn’t working or does that mean it’s just not cold at all?
Blower is not blowing anything. On low or high (1 through 4) it won't blow out anything.
At some point it only worked on high (4) but now nothing is coming out.
Thanks for the video! I believe I'm having the same issue. When I start my car it blows hot until I start driving for a bit. And even when I accelerate fast it will stop blowing cold for a bit then blow cold after a minute so if I could have your input I would greatly appreciate it thanks!
Also I've had the same issue with the bumper cover falling out any recommendations for keeping that on?
jfogal22 what part of the bumper cover? Center lower grill?
jfogal22 hmmmm....... have you had someone check the actual Freon charge and make sure it has the correct amount of Freon in it? My issue was either it was cooling or not, seldom any in between. I would go and have it checked. Or if your handy with tools and can understand and read dials, you can google / TH-cam information on what the low pressure side should be reading and what the high pressure side should be reading and then go to Autozone or a local parts store and rent a set of AC Manifolds to hook up. It’s pretty straight forward for the most part. You can add Freon with those manifolds also if it just needs a little.
@@jmaverick Yea it's the center lower like in your video I was just thinking about throwing another on there and sealing it with gorilla glue
@@jmaverick I've checked the freon myself with a gauge from autozone and it said it was fine so I thought it was the clutch on the compressor like they said it was on my older car
Im having a problem with my ac got it checked im supposed to change the ac high side line
Keara Reed Are you having the intermittent working/not working issue?
@@jmaverick that's the problem i have on my 2011 Sonata 2.4 Limited. When you turn the AC on is hit or miss, sometimes it works sometimes it doesn't. Is that the problem you had ?
CSorin Yes, that was our problem. It didn’t make sense when it worked and when it didn’t. We could jump in the car and it would blast cold air, drive 15 min, pull in, turn the engine off and get gas or just go into a store for 5 min or less and turn the car back on and the AC would blow warm or hot air. No rhyme or reason.
J Golden thank you so much. I already ordered the piece from your link even before you answered back to my comment. Thanks again sir. The only thing that I didn’t really understand is how you removed the thing outta there ?
CSorin well obviously you will have to evacuate the system to take the pressure off, but once you do get the pressure off there is a Snap Ring that is holding it in. You can buy snap ring pliers at any auto parts store, they are relatively cheap. Once you get the snap ring out then you may have to pry on it a little to get it moving because it’s been in there under suction and there are O - Ring seals in place that just need a little nudge to get them moving.

This is the valve I used, and they are available on EBay also
Hey where did you get the valve? I'm having a hard time finding it

I'm having an ac Issue now as well...it blows air it's just not cool air... wonder if this would help.....
Joey Calvo have you had the Freon charge checked? I would start there if you haven’t. I personally haven’t had anyone with the problem of just not blowing cold air ever, this valve typically fixes the random cold/hot air situation.
Condenser. Just changed mine
What was the original symptom?
Scott Welinski A/C Intermittently cold. Cold one minute, blowing hot the next time you use it.
Do you have to drain out the freon before you can put the compressor in ?
Zahlinr yes, it has to be drained. I had my system drained right before and i still used a hose and bottle to catch anything that was left.
J Golden then once the process is finished you would just proceed to recharge the A/C with Freon ?
Zahlinr yes. Make sure to find out exactly how much Freon your specific car requires and charge it
