any complaints about the a/c?

They replaced the sensor and and that cured the problem. Also, it cooled much better than it ever had before, even when new.
I have to wonder if those of you who have AC complaints, aren't having a problem with the automatic systems calibration, maybe even a weak or defective temp sensor. Just a thought!
A comment on some other statements made above. Humidity does take it's toll on the AC's ability to cool the air but I'm not sure I agree with the comment by McGraphics on the refrigerants being used today as opposed to what was used before. I've got a 2001 Honda Odyssey minivan that uses the same refrigerant and it cools the van just fine in 95+ degree temps and 80 to 90 percent humidity here in the Houston area, and I'm talking about a much larger space to cool down.
FWIW

Yesterday it was 83 degrees and 87% humidity. I have dual zone heating and air in my house and the 2 units were pulling full blast. When you walk out your door and feel something like a wet sock hit you in the face, your air con will be working overtime in your car too. I put my air con on maximum recirculating and point as many vents directly on me as I can. My Z's air works very well using that technique.

Reminder to those in high humidity areas, once the interior of the A/C units freezes, it will NOT cool.....it will be like blowing hot air over a block of ice. The A/C evaporator (inside A/C) will start freezing water from from air if water that condenses is not removed or if temperature is too low. This can build up until the evaporator is clogged and becomse a block of ice.
To melt ice, turn A/C off and put fan on high. Once ice is melted insure the recirculate button is on then turn A/C back on and adjust the temp control 68 - 78 and fan control back to auto. By keeping windows closed and the recirculate option on you allow the A/C to cool and dry the air inside the car.
My car has problem cooling vehicle if it is not moving, seems not enough air is pulled thru to cool engine and A/C. Remember that the air intake for cabin is taking the hot air from the engine compartment!
Hope this is of some help.

Intrepid thanks for that info., i'll bring it up to the service dept. of my dealer.

is it possible to put the R12 freon in our car? thanks for the info.

You would have to change out a lot of the system to go to freon. Not worth it.
As for the Phoenix people being happy, somebody brings up a good point about humidity. That may have something to do with it.
I just know that this system in a small interior isn't near as good as my two GM (one R12, one R134A) vehicles and struggles on a 95 degree day like we've been having to ever come off of high fan speed here.
I don't know that it is just the interior temp sensor keeping the fan on high. It isn't cool enough, either.

As Mannishboy pointed out, you'd have to change a lot of componenets to do that. What's on your car now (seals, hoses, etc.) isn't compatible with R12. From a cost POV, it wouldn't be worth it. Also, the dealer wouldn't be able to legally help you with this. R12 is being phased out of use and depending on where you are in the country, you probably can't find it in the first place. If you could, it wouldn't be cheap.

i took it to the dealer, and they flushed the whole system, filled it back up to the right pressure, and still is not that cold. i am going to take it back again, now that the weather here in nj is hot, and i can tested then and there once they are finished with it. i just wanted to know your opinions on the matter.
thanks

Back to the dealer...they said that they had been having problems with their equipment use to meter the correct volumes of refrigeran when replacing same, and as a result they had put to much in the system....???? Said that all was fixed (A/C reserviced/recharged...got the car back today. The compressor does not cycle off when it is not supposed to any more but the A/C air is not as cool as it was with the old compressor.
I took a cooking thermometer that has an un-metered range below 100 degrees and checked the air vent temperature for 5 minutes in the Z and two of my other cars. The Z appears to be 15-20 degrees warmer than my other cars.
QUESTION: CAN ANYONE TELL ME WHAT THE SPECS ARE FOR WHAT THE AIR VENT AIR TEMPERATURE SHOULD BE WITH THE A/C SET AT 60 DEGREES IN THE Z?????
THANKS.

I may be stirring up an old topic but I live in Vegas (dry - not humid) and I think the A/C is a piece of crap. I drive 30 miles a day one way and its gets so I can survive in the car but is it cold? Not in a million years would I call that cold.

i think the A/C is fine on the Z. I just set it to about 65 degrees and set it on AUTO. but then again.. temps around my area stay around 60 degrees. Its odd, but i get the smell when i turn off the A/C. When its on.. i don't have the smell. people are reporting otherwise

I live in Atlanta. You can cut the humidity with a knife. My Super Black Z cools just fine. You do want to be sure your A/C unit is on recirculate or it won't get very cold. My A/C will freeze your butt off. No problems at all. No smell either. I now have about 2300 miles on her. So far, So good.

All of my other cars produce 45-48 degrees air temp at the air vent when set on recirc and lowest temperture. So I took the Z back to the dealer and we got into a new Z on the lot and tested the air temp at the air vent while set on auto, recirc and 60 degree temp setting. The vent air temp went right to 48 degrees. Mine would only go down to 60 degrees.
Buy a $5 small outside thermometer at Home Depot and set your a/c as described above and if your air vent air temp does not get down to 48 degrees plus or minus a couple of degrees after 5-10 minutes you have a problem and should visit your dealer. You can be driving or parked at 2000 RPM to achieve this air temp.
The dealer finally repaired my a/c and it is frosty. I live in San Antonio with 95-100 degree weather and high humidity and after I start driving I have to set my temp at 75-78 degrees as the car gets to cold set at 60 degrees.
Hope this helps.
