My wife just came back from dealer where she tried to fix her AC on 2 weeks old Pathfinder (manufactured in June 2005) What are we encountering is, on longer drives AC stops to work and it is actually blowing only air form outside little bit cooler. All of the sudden car feels sticky from humidity (we live in South Florida) entering the car. Nothing will change if you crank AC on both sides down to 60. No cold air whatsoever. :temphot: After you stop the car for short period of time nothing will change. Only next day when you drive short distance (up to 10 miles) AC works normally (but not as cold as my other cars Ford and Mitsubishi). So she went to the dealer service. They told her to dive the car for 100 miles and come back with the problem (of course Nissan won’t reimburse you for those miles, nor gas since this is a lease I’m not taking my miles just to duplicate problem for technician and drive up and down on the highway just for fun) or to leave car standing here wit engine idling to duplicate problem. She said OK let it run at the parking lot and we will see. Then a manager came along and start explain to her, that AUTO mode in AC is really for nothing :confused: , It won’t work as your home unit. :fullofit: Anything above 70 degrees is really mixing cold air with heater box! And dual zone AC that is a joke. You can not have one side to 74 and other to 60!! :eek: According to them, and also my AC is actually hotter from that side set for 60!! I guess next step will be angry call to Nissan, but first I wanted to share this experience with you and maybe get some input from other users if they encounter the same problem.

BTW I have 05 Pathfinder, LE, NAV w/ electronic AC controls.

When I drove there this morning AC worked normally, but it was less than 100 miles, 1.5 hour drive time. But as I mentioned before after night spent in the driveway, nothing will happen until you drive for longer time. Dealer told me that they will leave the car running on the parking lot idling. We'll see what happens. I'm awaiting a call from them this afternoon.

Just got mine back from dealer. Apparently something came up on the diagnostics that indicates an A/C problem. Unfortunately it will be next week before the individual who talks to Nissan will be back from vacaton.

It must be a very secret language.

Resolution

I just got call from dealer, that some sensor on AC is malfunctioning and causing AC to freeze up. Once the frost is melted off it will start to work normally. Unfortunately nobody on East coast has this type of sensor. It is ordered from CA so on Monday another trip to service for repair...

BTW part what is malfunctioning: A/C intake sensor sensor in closed loop condition. FP number : 27700-5Z0000 sensor assy-SUN

I also noticed that at the beginning of a drive my A/C is blowing really cold air, no matter what temperature is set. I had it for 80 and it was almost freezing. Then after little while (approx 30 mins) i start o feel change downhill. From now on the A/C performance is poorer and poorer. After about an hour it finally craps out and it's short of breath blowing only hot air in. So I guess service technician assumption about some sensor being faulty is correct, I'll keep you posted how it went on Tuesday, when I have another appointment. Too bad I can not use the car this weekend while going on long trip. :damn:

This is intesresting b/c you guess are talking about the auto AC function on your truck, but my truck has no auto function and after standing idle for about 30 minutes the ac shuts down... and I don't mean blow slightly less cooler air I mean it only blows outside air. The last time this happened I checked the outside temp and it was 110 and I first thought the damn thing over heated (who knows), so I started driving around a bit and nothing happened, so I shut her down and restarted and everything was fine :huh:
So i did the nissan shuffle and made an appt. everything checked fine and i was good to go no leaks no nothing :3d_049:
I just shook my head and left, but before I left I asked if there was and auto shutoff sensor for the ac and I got strange looks and a big NO.
sO here is my question to people "is there an auto shutoff for the AC unit"?

A/C problem

I also experienced this problem when we took a trip that was about 200mi. We first noticed that it started blowing cool (instead of cold) air. We tried messing with controls (turning A/C off, back on, various settings) - it would not blow cold air --even with the A/C indicator on.

After maybe about 15-20 minutes the A/C then "kicked-in" and began blowing cold air. This repeated one more time during the trip, and then again on the way back.

We took it into the dealer a few weeks ago and mentioned the problem, and brought a printout of this forum with us. They ran diagnostics and nothing came back and even checked by running the pathfinder for about an hour and half with no problems reported.

We recently took it on the same trip and had no A/C problems. I wonder if this problem only happens when the outside temperature is > 95 degrees F? Outside temperature is the only difference between the first and second trip that i can think of (15 degrees cooler).

I guess we'll have to wait till next year to see how many other folks have this problem (if at all).

I know this is an old thread.
My 2006 LE is doing the same ****.
it has 43.000 miles on it
The dealer has admitted I am the third person in the last week that has had the same problem.

This should be a nissan fix not a nissan owner fix!!!

Oh well I am trying the link to the clubtitan thread first.

Then the stealership

had the same problem twice. First time, they added 1lb of 134A and it cured it (strange)- the second time it was an electrical problem caused by lower alternator output. First, we upped the idle from 450 to 600, (it idles lower with the Amsoil air filter until the computer relearns), then we checked and cleaned the frame electrical connections. Now it's back on line and working well. It's real voltage sensitive, so watch your volt gauge and see if you are showing less than 12.9 at any time?
