Hi All

I will really appreciate if someone can help me out on this. On a hot day when I need the AC most following issue happens:

1) AC works perfectly fine in the beginning. Then gradually less and less air comes out from the vents.
2) The air is constantly cold... and what little air that comes out of the vents after it stops blowing is still very cold.
3) Turning the fan to max, I can hear the blower engage and blow air harder. But hardly any air comes from the vents.
4) Turning OFF the A/C unit for 5-10 minutes, and then starting again seems to fix the issue but the the whole process repeats again within few minutes of driving

I took to the car to two different dealers and they both said they cant reproduce the issue and don't know what to fix. I am not sure what to do now, even tried calling Nissan USA but they said if dealer cant find the issue there is nothing they can do. Car is pretty much unusable at this point for long drives on a hot day.

I'm having the exact same problem with my 2014 rogue SV. Exactly identical.

I just dropped it off for the third time at the dealer this evening. They can't reproduce it either, but happens to me more often then not. I'll let you know if they come up with any solutions.

Current fix attempts were resetting the vents and did not work. Hopefully third times the charm!

Is the cabin filter clean?

Wouldn't be the cabin filter as air still gets through for a while. Almost feels like the vent sacking in air from the exterior closes (in my case) stopping the air from flowing into the cabin

Your evaporator coil is probably freezing up. This causes less and less air flow as the ice blocks the coil. Air is still kind of cold but not quite as cold as normal. Turning ac off and running fan for a while melts the ice and air flow returns for a while until ice builds up again. The cause is low pressure in the evaporator which makes your coil run at an internal temperature of probably less than ten degrees F and sometimes even negative degrees F. A leak or a blocked/faulty expansion valve is usually the cause. If it happens again pull into the nearest parking lot and run your fan without ac, look under the car and see if there is a surge of water flow from your drain pipe, this is your ice block melting and coil freeze-up is your issue.

If this was the case, wouldn't it happen all the time as opposed to intermittent?

Temperature, humidity, engine RPM, length of trip, all of these have to be just right for coil to freeze up. A short, stop and go hop to the supermarket may be fine, but a long highway drive in full recirc might be enough to build up ice in a system with low refrigerant. The original poster mentioned long drives on a hot day. I myself suffered loss of air flow and wimpy cooling on a long six hour drive from NY to MD. The day was hot and muggy. No problems on the return trip, different day, cooler and less humid.

Got it! I just put in a call to the dealer who's doing the work on my Rogue. Will update with their findings.

I have the same exact issue, dropped the car off for an oil change and they also couldn't replicate the issue. went on a road-trip right after and it happened once. All i have to do on mine is to press on the A/C button, wait 5 seconds and press it again and all is good. They better figure out what this is cause it sounds like many of us are having this problem.

You may be onto something, but the dealers have told me that they ran the cars AC for > 30 mins(sitting in the garage though) and still can't reproduce the issue and since the car is in warranty they will not replace anything until the issue is reproduced.

Even I tried running AC on a colder day on full blast and it seems to be working fine for around 15 mins drive, this problem seems to be more persistent on a hot day.

Running the car at idle will not reproduce the problem. My Rogue runs an evaporator pressure of 35 psi at idle, but drops to 10 psi at 2000 rpm. The coil is at 40 degrees F at idle, but drops to 7 degrees F at 2K rpm. The coil temperature sensor is located up against the evaporator coil and is supposed to cut the compressor in order to prevent freezing, but if the ice is not forming at the sensor it will not see it. All coils will form ice at random locations depending on air flow stratification and flow of refrigerant inside, so location of freeze sensor may not be optimal. My own problems point to low refrigerant. My freeze sensor is probably not in the ideal location to catch ice conditions. I will look for leaks as low refrigerant is the fundamental cause of my problems. The temperature sensor is supposed to protect you from freezing, but is not the cause. I had to edit this post because I thought the low pressure switch would lock you out in the event of low evaporator pressure, but since it is a combo hi/lo switch located on the high side and set for 20 psi, it is basically a "my system is empty" switch.

So after a 3rd visit, they replaced the intake temp sensor. We'll see if that works or not! Apparently they could not find the fix and this is what nissan canada suggested they do.

Let us know how it goes.

Absolutely! Going to be testing the s*** out of it! Lol

I had an '71 Monte Carlo that did the same thing. The evaporator was under the hood sticking out from the firewall and it would become a solid block of ice. You could see the ice where lines went in and out. As soon as it melted, the a/c worked fine. Turning the temp up slightly on long trips cured it, but I wouldn't accept that on a new car in warranty. This was actually a second car at the time.

Being a little low on refrigerant can cause it also.

Any updates to this problem? I believe I have similar issues - this is a very frustrating problem to me. I live in Florida, bought this car new in January. My biggest issue is when it is "cold" outside - it blows hot or warm air no matter what temperature I set the A/C to. I've had this problem since I bought the car. I did not have much of an issue in the summer so I thought it was working fine. Now that it is getting cooler and cold, I'm seeing the same issue come up again.

This morning, it was "61 degrees" outside, it felt warmer than 61 degrees. What I think the problem is, is that the car gets confused or tries to balance the temperature outside with inside. So if the car thinks it's 61 degrees outside, and I set it to 66 degrees inside, it will try to warm up the car. To me, if you have the car at 66 degrees - it should be blasting cold air, not with this car. I showed it to the dealer manager this morning and he said "not to sugarcoat it, but that's how these things work." He said he has a lot of people complaining about it and that's just the way it is. To me, it is unacceptable and I'm trying to figure out my next step. So if anyone who has had a similar experience has fixed this somehow, I'd love to hear. Thanks in advance.

Bass4ever any update on the A/C?

Don't put your Hope 's up with NISSAN !
Their Busy with other things right now....

Like ROGUE ONE !

NISSAN never again......

2016 Rogue with 7,000 miles: the air stopped coming out of vents after about 2 hours in Florida sunshine. Pushed all the buttons, including fan speed, mode, recirc, etc. No change. Eventually it started working again. Noticed that this post hasn't had any "action" since 2016. The "freeze-up" mentioned in one post above was interesting and could be reason for intermittent problem. Taking car to dealer tomorrow to get my problem noted before warranty expires. Expect to have to pay for the pleasure as it will likely come back NTF.... Any solutions since 2016? Thanks.

I have the same exact problem with my 14 Rogue SL. I also have been to the dealer multiple times and nothing has come of it. Don't understand why after so many calls and complaints from all of us they haven't recognised there is a problem with the system. This is going to be my last Nissan as well. the 1-800 people are as useless as the dealers.

Its a small seal on the bottom of the cars AC hose to the compressor, it needs disconnecting and reconnecting, it has a slight leak and freezes up over the period of about a hour, happened to me and I posted it somewhere... they told me some come from the factory that way, slightly offset and cause that problem. They did it to my car and its been fine ever since.

My 2016 Rogue SL has a similar issue, but its only with the middle air vents on the drivers side. Sometimes it doesn't blow the air fully, even when the fan is on the highest speed. I am using the Rogue for my drives on the turnpike to and from Miami, and the weather can get very humid and hot. I haven't experienced this issue in any of the Hondas we own.
