I was a tech before these newer compressors (80's) and had to learn about them after my Hyundai Tuscon had a cooling issue with high low side pressures. I chased it until I found these type of vids. Replaced the valve and it brought the pressure back to normal and cooling was back to normal 46 degrees after being stuck at 60 prior. Thanks to you for doing these!!!! Saved me a ton of money doing it all myself.

Another visual check is to see how clean the condenser is. I just did one that was almost completely plugged with bugs dirt dust cotton etc. I actually pulled the radiator out (didn't want to crack the AC unless absolutely necessary) so I could thoroughly clean all fins on both. Starting pressure 30/270 @80°. When cleaning was done it was 37/175@ 77° blowing a nice 42° in the cabin now. If I hadn't thought to check and clean it, I would have done a orifice, dryer, and flush, and I doubt it would have fixed anything.

wolf2351 you can’t trust mechanics anymore, the world is so fucked anymore and you can’t trust or believe anyone. I told my Dad his mechanic was robbing him. For years I kept telling him, but he was like naaaa, he wouldn’t do that he’s a good guy, bla bla bla. Then he went to get a noise looked at and they said he had to replace his axles and power steering pump, 1200.00. But eventually dad found out when he noticed his power steering pump wasn’t changed and I got to say I told ya so. I’m sure he didn’t need, or get new axles either. Fix it yourself people, it’s not hard unless you lack time like a lot of us.

Most people just look for a click out of the compressor and think it's not the issue. This shows that even if the compressor clicks on, it could still be at fault (Compressor control valve in this case)

Well, here it is two years after you posted this video and my wife's 2015 Nissan Altima is doing exactly what is happening in this video with very similar readings. I'm doing this job now however, (like you said) a bit hard to find the replacement part. I think NAPA may have it. Lots of people have complained about AC compressor failure's on these Nissans. I'm guessing its this little part like in your video that may be at fault however, Dealerships and repair shops just see an opportunity to swap out entire systems and make a little more off folks. I find it a little odd that this fails and the car is only 5 years old with about 60k miles meanwhile, we have a 12 year old Hyundai Entourage with just under 200k miles and it's AC system is still original and going strong. Anyways, thanks for the video. Edit follow up 8/5/2020: It was the control valve for our 2015 Nissan Altima SV. NAPA did not have the part like I thought. AutoZone said they could order one for about 85-90 dollars, (part number MT3452 ) from Santech. This part only fits 2013 through 2017 2.5L Altima SV & SL models only. I found one on ebay by typing in the part number for 26.00 dollars and free shipping. Took a chance and it seems to be working for now. Not sure how long it will last as the part is made in China. If it get us through the remainder of the summer I'll be happy as it's better than replacing the whole compressor. Good luck to anyone dealing with this.

I don't want to use pliers and more force since I have seen on other videos that they use pliers and they break where the connector plugs in. If it breaks, the rest of the valve will be stuck inside the compressor and YOU will have to remove the compressor and if you cant get the valve out you have to problems. I don't want use any w40 or other stuff since I don't know if the AC will get contaminated. I will keep trying to see if it comes out, wish me luck.

Is this a real question? Are you questioning the machines manufacturer or are thinking my valves are defective or I faked something? The hoses go inside the machine to the manual vales on the control panel for which the pressure gauge is tapped into. This way you can view the vehicles static and running pressures without allowing the refrigerant to flow into the machine until you are ready for recovery.

Unfortunately, some older A/C compressors use internal mechanical control valve and there isn't any sensible way to fix the control valve if it's failing. Instead, you have to always replace the whole compressor if it cannot push the low-side pressure low enough.

Great video! I have the same exact car with the same exact readings and the same mentioned problem. I went and had an evac done and that control valve replaced, but it didn't resolve my issue. I ended up paying the shop to change the valve I bought on eBay while it was in the lift. Question, should any oil come out when you replace this valve? Because I didn't see any. Just curious. Also, since my issue persists, is there any way to test the new valve I bought is working? And if this wasn't the fix I needed, what else could cause these pressure readings? I noticed you ended up changing the whole compressor. Could it be that my compressor is just bad. I feel like I've heard others complaining of Nissan compressors prematurely failing. I assume buying a new compressor includes this valve? Thanks to anyone that might help me here!!

you can test the valve with 12v applied carefully at terminals, theres a another video that shows the difference between a good an bad one.

Hello, thank you for making this video it gave me some ideas on where to start diagnostics aspects. I have 2012 Altima and my AC issue is that on a typical hot day when I first turn it on it blows hot air for quite some time until finally turns on. I usually have to mess with the AC on off button which I’m sure not good for clutch plate but it does helps. Also when is on it’s not blowing a lot of cool air like it should be and in AZ heat it’s pain in the butt. I do not have any leaks since my father check it every summer. Could you kindly tell me what could be wrong with this AC system?

I have a PT cruiser it has a low pressure shut off switch and a high pressure shut off switch is thst the same as the control on the compressor,?

What if the high pressure gage is vibrantes at 200 psi. Does it mean that the compressor failed or the valve in it.
