Anyone else having problems with their air conditioning systems? Two failures so far - one last summer (coolant leak), and another today. When I turned on the air, I heard a hissing sound, which quickly went away after I turned the fan off. No cold at at all. I just happened to be near my dealership (I live 2 hours away), so I'm hoping it can be fixed before I head home. Second problem in 2 years... anyone else having this issue? :mad:

Update...

It was an O-ring problem that led to the system losing refrigerant. Seems this ring was too close to a heat shield. Repaired under warranty. Cool. ;)

Had an AC problem last spring. Dealer was unable to find any leak. Recharged coolant and have been fine so far. I use the AC almost all year round, thus it is on every day for an hour or more. Great for defrosting in the winter.

Only problem I had with the A/C was a critter (squirrel) getting in my intake and making a nest. I guess this will have to be a yearly check for me, this happened with my old 2000 Civic Si twice and now the Xtrail, which is funny because the vehicle is not home alot. Now I'm worried about my new car. Anybody have any advice on how to control squirrels?

I have problem with my Nissan sentra 2000 car, the A/c stopped working today morning. It was blowing cold air when started the car, my rear window had mist to clear that I have turned the heater on. Once the mist got cleared i have moved the control from heater (red color) to cooling side (blue color). I see now still it is blowing only hot air. The cold air is not at all coming

I am not sure if I am posting this question at the right place. please suggest me the correct place where I have post this messsage.

Can someone help me to resolve my A/c problem.

Thanks

AC can simply have a holed pipe by a stone sadly, so it will run and then get pumped out of refrigderation gas, engineers can purge the system with gas that shows up under uv light to see if leaking easily and cheaply, also it might be that the gas simply needs recharging as most units need a top up after a few years (4-5).

Problem with AC in 05 XTrail

So just took my '05 Xtrail in for AC check - - -I just thought the refrigerant was low and needed recharging . . . but my mechanic found a leak by injecting a dye in to the lines. COST? $1100CDN+for the repair. I didn't go through with it, but he did call my Nissan dealer for me. I'm past warranty by about 7000 clicks. But the odd thing (red flag) was that when the mechanic called Nissan, they had the required $569CDN part in stock (???) My mechanic thought this was strange - condensors are not usually stocked (I guess not at other dealerships). . .made him think this is a common problem??

I got the same "a rock may have come under the car and knocked the line" bit, but really, how often does that cause this exact problem, and cars drive on roads, likely over rocks all the live-long day? Does everyone's AC stop working?

The AC petered out this summer. It hissed for while before - should have had it checked earlier!! My mechanic said that I could go ahead and recharge it, but he couldn't guarantee me how long that would last, as it was clearly spraying/leaking at the line near the radiator. The condensor needs to be replaced for it to work problem free. Argh.

My 1996 Nissan p/u only seems to work correctly when temps are lower, as in the morning. After it warms up, it only cycles once and won't cycle back to cool. I changed the low pressure switch on drier and recharged but nothing has changed. Is there a high pressure switch in system? Could it be in the cooling unit underneath the dashboard?

i had similar problem, there was green liquid leaking from under the car and it was a small round seal that had corroded. they replaced that then regassed it and that solved the problem it cost about £100

You did it or a garage did it?

Mine lost the green liquid. Last summer and i was wonder if a filler kit was able to do the job.

I have a 2011 Rogue. The AC wasn't as cold as in the past so I put a gauge on the low pressure line and found it was low on refrigerant. I fill it with the specified refrigerant to the low end of the full range and it worked much better. I didn't want to overcharge it. Then, after a couple weeks I added more to get it into the middle of the full range.

Now it alternates between blowing out cold and hot air.

Anyone have any thoughts on what I did? Any ideas on how to fix it? I have 110,000+ miles and don't want to put more into the fix than the car is worth.

Thank you all for the information on ACs. These units are very expensive to recondition or replace here in Rio de Janeiro too. Unlike a fridge, the refrigerant gas leaks out over time, so a refill is the commonest maintenance task.
Regarding very hot (sun temp. 40C.+) weather, if your roof is a dark colour (mine's black, the worst), you might want to consider spraying it white or installing an upper roof panel with a space for air to flow through (in my case, the sunroof precludes the idea), as seen on many Land-Rover Defenders.
Also, after back-blowing the AC outlets on my T30 that has never had a cabin filter since manufacture in 2007, I'm considering not using a very fine filter, as it would restrict the air flow too much.
Any other ideas on keeping cool would be most welcome.

Move to Québec this weekend you ll forget about AC for a while.
Drove down to Gatineau and heat at full blast is barely warm.
Worst part is that only drive side gets the warm air(wtf) and passenger side is cold air only.On top of that no air coming out towards windshield of feet,no matter where the knob is.

Hi OTOMODO, How strange ! Could there be ice or hibernating squirrels caught in the air ducts. Good luck, and do let me know about the solution. Cheers, BRIAN -GX-Trailer

Finally arrived safely at home.After 1h30 of cold driving.


And it seems like the muffler had a chunk of ice stuck inside


On the way back,i had to play with the recycle button to get hot air,but with no ac the windshield got "foggy" really quick. (i know no phone while driving but it was for science)https://vimeo.com/155271109
