This forum has been about as much help as CAC. Understand this concept, the fan/heat/AC system should not default to the snowflake. It should default to where the driver left it--or off. If it truly is meant to defog the windshield, then shouldn't it be programmed to come on only in defog mode? I could live with that. Personally I think this is a screw up. I think a foreign engineer programmed this and used 40 degrees thinking it was Celsius. That would make sense, the AC should come on automatically if it's over a 100 degrees. That would be a great safety feature. And I think the sensor and the programming mechanics are in a sealed unit, so it's not financially feasible for GM to offer buyers a re-program or a new sensor. And regarding the OnStar hissing, I am starting to get real paranoid. Do you realize the FBI, or someone stalking you would know exactly where you are with this car? Do you think Tony Soprano has OnStar in his Escalade?

“This forum has been about as much help as CAC. Understand this concept . . .”
I think that:
1. Several people here (including me) do understand that some series of design parameters and \ or judgment errors have resulted in the A/C compressor running at times we don’t think it ought to run. Now that I understand the behavior, I do simply turn the A/C off when I don’t want it running.
2. No one here now has a huge problem with either the hiss or the overly aggressive A/C engagement programming.
I have owned and driven so many cars I have lost count (in about 40 years with a driver’s license) and I cannot recall one that did not exhibit at least a couple of annoyances. Some small & some rather large. These 2 items (and again I will grant that if I ruled GM they would not have made it to production) fall into the annoyance category – for me. Heck, I am annoyed that my driver’s door often does not stay at the full open detent \ position by itself. Oh, well . . .
The fact that no one here has a ‘remedy’ for the 2 issues you raise is apparently also an annoyance to you.
Sorry.
If a solution existed, I believe that it would have been posted here or on another Board I follow closely. I don’t believe that anyone is intentionally withholding information.
And perhaps Tony will now use his wife’s Porsche SUV (something I would have bet serious money 20 years ago would never exist) when he has a concern about OnStar surveillance.

You are not being fair at all comparing this forum to the CAC. This forum is extremely helpful and has been very helpful to me. Everyone tries to help each other, and as Ray just stated, no one is withholding info. If we have it, we share it. Now to the CAC -- they are worthless, useless, stupid. They are not engineers but more like telemarketers. They look in the manual and call the dealer while you are on "Hold." Any idiot can do that!!! I don't even call them anymore. So, I think you are being very unfair with your statement critizing this forum. All we are trying to do is be helpful. We didn't manufacture this car. When I want heat, I use my automatic climate control or when I want a/c. Then I turn it off. So, I don't have any problem. If this forum bothers you, you shouldn't participate in it. And, I'm not being fresh either, just realistic. I enjoy this forum very very much and get lots of pointers.

One of the main reasons I review this forum is to keep up on any information about my GXP. I dont rely on GM anymore for that information due to my last vehicle.
I purchased a 2005 Chevy Equinox in July 2004. It was a great vehicle to start out, but they i quickly found problems with it. The main one being with the heating system. After only a few thousand miles on it, I was browsing the Equinox forums, and discovered that many drivers had issues with their coolant. So, i decided to check mine, and it looked literally like chocolate syrup! needless to say, i contacted dealer about it, and they said that "GM" hadnt issued any service bulletins about it, so dont worry about it. After a few months of studying the forums though, i found that it was a coolant hose problem; they were manufactured overseas somewhere, and they didnt use the proper preperation to treat the hoses, and it was reacting w/ the dexcool coolant. After many calls to my dealer, they finally contacted the right people and replaced my hoses (all 7 of them!) to fix the problem. Of course, i traded that vehicle in June 2005 for my GXP though, and i've never looked back!
Forums like this are a great way to share information with actual owners, and keep the dealerships out of the loop. They are only as good as what GM lets them be.

I too, have owned many cars and most have had minor annoyances. But... the GTP I traded in was my favorite car of all time...better than my previous Bonneville. That GTP was perfect and I loved it. The only thing that happened was it got up to 69K miles, so alas, I needed a new car. And I guess I thought I was going to like this blue-green crystal as much. And I guess I didn't think I was going to have to accept this stupid AC programming, especially since my salesman told me it could be re-programmed. I'm disappointed I didn't find a solution here, but satisfied that evidently none exists. One more question if you don't mind.... does anyone know how to get past CAC? Is there another level to take this?

Why don't you ask the Service Manager for the name of the representative for your dealership. Maybe he could help you. There is always the BBB (their number is in your manual). GM participates in the BBB. I didn't bother though when I was doing all my complaining about the hissing/humming because I figured I would get nowhere. My hissing/humming is so minor I just ignore it now since it goes off after 15 seconds and does not interfere with the performance of my radio/cd player. when my nephew listened to the hissing/humming sound he called it "static." But, my problem was I was fighting on "principle." GM was aware of the problem with the 2005 GXP's and yet put the same problem in the 2006 GXP's. I didn't even know I had this problem until someone on this forum told me I did. He said open your door and put your ear next to the speakers, you'll hear it. And he was absolutely right. I did! That's why I think this forum is great. Ray is very very helpful as is Robert Hammen, but we don't hear from him much. He helped me too alot re the tires. And he was correct. I have also written to two people at GM and received NO reply.

I had been doing business with a small, country dealer since 1977, and yes I did trust them. I took my car in rarely and for small problems that were fixed promptly the first time. They even gave me a ride to work when I had to leave my car. Last fall they closed down; the father/owner became too ill and I don't think the kids wanted to work that hard. So the dealership was sold to Hundai. I miss their personal, friendly, honest service. Anyway, it's a lovely day here in New England and we're coming into AC season. Who knows what matters may concern us by September. I'm satisfied that if a solution existed for the AC (re-program or new sensor) someone here would have found it. I plan to write letters on this topic and if I get anywhere, I'll let everyone know. By the way, I think the snowflake default is far more annoying that the hiss or the GM badge.

Sorry to hear the AC issue is ruining your GXP experience. I am not sure how carefully you read the owners manual or how much you have experimented with the system, so let me share these thoughts. I have a 2005 GXP with the manual climate control and the AC light did not come on all the time in the winter. A review of the owners manual for both the manual and auto climate control systems indicate that "the system will automatically turn off the recirculation and run the air conditioning compressor, unless the outside temperature is near or below freezing." when the selector is set for FLOOR/DEFOG or DEFROST. (In the case of the manual system it indicates 40F vs. freezing). Have you tried using the selector in the VENT, BI-LEVEL, or FLOOR positions and see if that continues to activate the AC compressor? The other important thing to understand is both climate control systems are very sophisticated pieces of equipment. If the compressor is activated it is by design and mostlikely serving its intended purpose. Maybe having the compressor on is more of a concern with higher fuel costs, but my guess is the effect is minimal (the car does have a V8). Also if you check further back in this forum there was a link posted that led us to more detailed info about the operation of the climate control system, specifically in regards to the parameters it follows during remote start. Hope this helps.
For anyone who might care, I found that when listening to a CD, if you want to fast forward or reverse the song you are listening to you can press and HOLD the up or down button on the left side of the steering.
No complaints about my GXP!!

Thanks for the tip about the seek/scan buttons on the left side of the steering wheel when you want to fast forward or backwards playing a CD. I tried it this morning. Works much better than the actual reverse or forward buttons -- they take too long. Thanks alot.
