I agree the hissing is freaky, but it goes away in a few seconds. The AC comes on every time you start the car, which is nonsense nine months out of the year in New England. CAC is totally useless. They wasted a month of my time. My dealer and CAC say this is normal operation to help defog the windshield. Duh! If's it dry out, why do I need to defog my windshield? The AC should default to where the driver left it, and there does not seem to be a fix or reprogram for this problem. I should not have to press that snowflake every time I start my car. Neither should I have to drive around wasting gas with my AC on. This happens in manual as well as automatic climate control. And it happens in every mode. I'm thinking of installing a kill switch. Do you think that would void my warranty?

With the auto-dual climate system, if you leave the vent control set to off, the AC and fan do not come on when you start the car.

Exactly, so that is why we have no problem. when I'm not using my ac or heat I turn it off. when I want it on, I turn it on. The salesperson did tell me when I purchased the car to always leave it on. I had no idea why he said that, but I turn it off when I don't need it. Why leave it on. I do exactly what I did with my other GTP's. Chats1

when I am not using my ac, I turn it off. When I want it on, I turn it on. I always use automatic climate control, but turn it off when I don't need it even though the salesman told me to always leave it on. I don't know if the remote starter has anything to do with any of this because even though I have the remote starter with my car I have no need to use it. My car is always parked inside -- in my garage, at work, at the mall, etc. I don't understand what this ac problem is. As far as a killer switch, I would be afraid of installing anything myself in this car because if you mess something up, your warranty would be void, unless the dealer does you a favor and just puts it under warranty. I have been going to the same dealer since 1992 and have bought five Pontiacs from them, so they know me very well and I never have any problems with them and I trust them. when I have a problem or think I have a problem, I go to the dealer.

I know if you shut off the entire heat/AC system, it doesn't come on. But... then when you turn on the heat, the frigging snowflake light comes on. I used to leave my GTP set to where I wanted it, and it always defaulted to where I left it. This stupid system defaults to AC if the outdoor temp is greater than 40 degrees F. CAC and the dealer say that's to help defog the windshield. If it's dry and 41 degrees, I need heat not AC. My old dealer, where I bought four Pontiacs closed down, so I had to go thirty miles away for this.

when I turn my ac/heat on, the snowflake comes on. I don't worry about it. When I don't want ac or heat, it's completely off because I turn it off. Where did you get the 40 degrees from. In the beginning when I got the car in August I read that manual 3 times and was looking for what degrees do I turn off the fan. I couldn't find anything so that's why I don't worry about it. My other car said 37 degrees. when my windows get foggy I just put it on defrost and then when they clear I turn it off. Isn't this fun. I decided I'm not worrying about anything on the car. It's under warranty for 3 years and after 3 years I either sell my car or trade it in and get a new one. Now, I'm thinking about what I want to buy next. I have 2 l/2 years to play with different ideas. Don't even call the CAC, they're stupid. I'm glad that I'm not the only complainer!!!

I have dual climate control. AC is off when system is off. I don't quite see what the fuss is about.
Correct me out there if I'm wrong, but most new cars will run the ac unit if the driver chooses any defroster function, and that includes cold weather stuff. Remember, ac removes moisture from air, a good thing even if it is 10 degrees out and relative humity is very low. I think most people don't even realize their ac is on in most models.....

chats1, you are correct. i was mistaken when i said my GXP didnt come with OnStar. What i meant to say was that it didnt come w/ the Navigation system. I forgot that Onstar was even installed because I have never used it, nor had any reason to. I have pretty much everything else you could order in it though, except for the Nav system. It even has the Monsoon speaker upgrade, so i dont think that would be causing the hissing. it sounds to me like there is something going on that is being amplified by the speakers, like an entry alert, door open, etc. since i dont have that noise, i guess ill never know.
The best thing i love about my GXP, other than the POWER, is the fact that there arent many others on the road. i have seen only 1 other, and that was at the end of last summer. i havent seen any others on the road where i live. i love to know that i have a special car that not many have seen before. I really take notice too as to who else drives the kind of car i drive. I used to have a chevy blazer, and after i got it, i immediately started noticing all of the other drivers on the road driving blazers, and was always comparing mine to theirs, lol. im glad i dont have to do that w/ my GXP. even when i see the new mustang gt/cobras on the road, i dont have to lower my head in shame now because i finally drive a car that can def. give them a run for the money!

I agree with you completely. when I want it on, I put it on, when I want it off, I turn it off. If it's still on, I'm not aware of it. I don't hear anything.

I have everything also in my car except for the Navigation system. If I get lost, I use my mouth or get myself unlost!! I never had occasion to use OnStar for help but I do use the phone. You can also access the phone through the Mute button on the steering wheel by holding it down and it connects you to OnStar, besides the rearview mirror. I also love this car because you don't see yourself coming and going. I have only seen one in a parking lot since I got mine and last week a fellow stopped me in the garage where I park at work and asked me how I liked the car. He just ordered one. He said it's really really nice and he loved my color (Dark Red Cherry Metallic).
