There was a technical service bulletin issued for a problem with the a/c on some 2005 cars. The problem seems to be related to improper pressure in the freon charge. Have your dealer research this. If they can't find it, you might want to call the Customer Service line and see if they can dig it up.

Heat Problem by fotorich

Thanks for the reply Stan but the AC was not in use only fresh outside air. Customer Service just refered the problem to the local rep who to repeat says this is normal.With an outside ambient temp of 75 degrees fahrenheit and the temp controls at 60 and the AC off no car should be blowing 110 degree air into the car.

I'm afraid that you are experiencing the greatest down side to owning a Corvette; Chevy dealers. My bet is that the car is still under warrantee, right? GM in general, and Chevy in particular, discovered early on that lying about a warrantee problem is much cheaper than fixing it. They have adopted this as a business model. My sympathies to you.

I must say your'e absolutely correct in making these statements that chevrolet just lies instead of fixing the problem..I've been there I know....and they have the nerve to call it the new American Revolution...what a joke!

A new wrinkle has been added to my over zealous cockpit heat problem. I called the GM customer service center for the 5th time, and again I was told the rep would not speak to me. I was advised to call the head of Roger Dean’s service dept. and make a new appointment. Rob McDonald argued with me while looking at a photography thermometer accurate to ¼ of a degree, that it was normal to have 120 degree heat blowing from the vents. All they did was fill out the paper work and send me home, a 50 mile trip. On the way home I turned off the AC and the temp started to climb to the ambient temp of 85. Then out of the blue I felt cool air coming out of the vents. The thermometer in the vent showed a temp of 78 and the cars sensor said an outside temp. of 85. Somehow with the AC physically turned off, you know line through the snow flake, the AC was on and running. There has to be a major computer problem when a car can turn on its AC while still turned off in the cockpit.

Hi . I owen a c6 convertible my self ! An I did what you did I turned off the Air Conditioner and set the seating to fresh air and the temp of 60 Degrees. well the air that comes in is from the out side air the fresh air vents comes from the front of you wind shield which take air from out side as well as air from the motor. that might be the issue here.

I only have a C5 but I can say from experience that telling when the automatic features are on and off in not straight forward. The system off position with outside vent open does come past the hot fire wall area and before temps outside get to needing A/C the vents will require A/C to cool things off. The dialed temp on the display, even if at 60 or much higher is meaningless if you are not in automatic mode so is not a good indicator. However, finding a really good C6 tech is where the solution lies, if the closest dealer is 50 miles away I don't know what to suggest except to search for more web input in corvette specific discussions. Good luck.

Thanks to all who have responded to my HOT C6. Let try and explain the problem again. After a day or more, and starting the car for the first time; the AC, fresh air and temperature controls having been left as follows:
AC off (Snowflake with slash line)
Temperature controls set at 60
Outside air open (interior recirculation off)
Fan set at the second third or forth setting.
When starting the car, and driving for a reasonable amount of time, under these circumstances the temp of the outside air coming in is usually not more than a few degrees warmer than the ambient temperature. This is true even when sitting in heavy traffic. Under these conditions the occurrence of extremely hot air blowing from the vents is rare. I repeat, rare but it has happened.
 
However if the car engine is stopped even if the ignition is only turned off momentarily or for an hour or so, with the comfort controls set as described above, the air coming out of the vents will rapidly climb to 100-120 degrees Fahrenheit. I do not mean to imply that hot air blows and than dissipates as one drives the car. I mean the hot air will continue to blow and climb as you drive at highway speeds. The only relief is to turn on the AC.
 
Now I do not like to drive with the AC on all the time especially on a nice day. It also robs the car of power and eats up gas mileage
 
Fotorich.

C6A606 test drive(s) Saturday AM by rayainsw

I drove 2 Coupes, back to back.
1 = MX0, 3LT, NAV (Std. \ base suspension)
& 1 = MX0, 1LT, Z51.
 
Brief background. I have driven 4 door sport sedans for many years. Last Corvette I drove was a ’98 or ’99 C5 owned by a business associate about 5 years ago. Last one I have been inside, except at a show or (stationary) at a dealer, was a Y2K C5. My current ride is a 2005 GP GXP (5.3L V8, 4 speed manumatic w/Paddles), with published quarter times generally clustered in the low 14s.
 
Paddle Shift A6. One of the reasons I have waited until now to allow myself to seriously consider a Corvette has been the previous 4 speed automatic trans. No offense intended to anyone with that trans., but each of my past 4 sedans has had a 4 or 5 speed manumatic trans. – and I know I would miss that feature, a lot. ( I have posted several reasons for my preference elsewhere on the Forum. ) This 6 speed trans. with paddle shift manumatic function is an acceptable implementation. Shift response to paddle command could certainly be quicker, but I am reasonably certain now that I could adapt. Otherwise, the driveline is smooth and refined. Engine response is always sharp & immediate. LS2 = great V8!
 
Z51. Not as much ride difference as I’d expected, but expecting to put 15K mi / yr on what will be a daily driver ( unlikely to be driven on a track or auto-X ), cheaper & longer lasting front tires, etc. mean I’d be fine with the Base suspension. I did not stress the car, handling-wise, in my drives, and thus would not have been able to evaluate any difference(s) in ultimate limits. I trust the published numbers – as I believe the Quarter Mile ET-s I’ve seen.
 
The ride of the base suspension suits me & my driving requirements just fine. The ride is certainly firm, but I found it well controlled \ damped & I expect that it will be livable for my long trips as well as my commute. Also (and one reason I did not fight the suggestion that I drive a Z51 as well as a Base car) neither of these 2 cars showed any signs of extraneous noise, such as creaks or groans or squeaks from interior plastic bits rubbing or from anything that might not be bolted (screwed, glued) together perfectly. I noticed no wind noise at the (brief) 70 MPH cruise intervals. ( Sound systems were off during all of both drives. ) I presume that it would be the same at any speed I’d be comfortable holding & cruising = typically 80 MPH or so. No vibrations noted at any speeds – in either car. I heard no ‘click’ on brake applications.
 
The overall impression was of a very well engineered & carefully assembled car. Remarkably so. Kudos, GM.
 
Sport seats = excellent comfort & support! 1LT \ base seats, not so much.
 
The controls and displays are well done & I felt immediately comfortable in the car – and given that the driving position is a good 6 or 7 inches (or more) lower than anything I have driven in a long time, that really impressed me.
 
Acceleration. Well, ‘acceptable’ hardly covers this. ( New cars, low miles, no abuse.) But there is definitely enough acceleration ability to appreciate the difference between my current sedan (again, low 14s) and a 13 flat or better sports car.
 
Sound. I will probably replace the exhaust at some point, with something just a bit more aggressive – but the combination \ blend of engine & exhaust was OK. For now.
 
Handling. I certainly did not stress these cars. They both felt sure footed, planted, confidence inspiring. I expect that it will be rewarding to drive at 6 or 7 tenths, without being punishing to drive over imperfect surfaces.
 
Steering. See above. And: Effort, response, road feel, & kickback = all excellent on the 5 mile (or so) loop I drove.
 
Outward visibility. OK. Rear mirror size & placement, etc. is not quite as good as I had hoped (and I am used to) but I think it will be OK. The only remaining issue \ concern for me her is the low roof line & ability to see things like overhead traffic signals. Best I can tell, I ‘lose’ about 6 to 8 inches of windshield height, compared to what I am used to seeing, looking forward. My ‘Solution’ = I will order the CC3.
 
HUD = very cool. Even better than mine. I have one in my GXP, and use it literally all the time. This particular example had a slight ( but would be annoying ) distortion, likely in the windshield glass at that particular area – as I moved my head side to side while driving. ( Not caused by polarized sunglasses. ) But the Tachometer display as well as the gear selected & the MPH means I would even more rarely have to look down at the instruments. Well done.
 
3LT. 1LT. I already knew that I would want the 3LT. As stated, I found the sport seats (2LT & 3) to be exceptionally comfortable as well as supportive. (I am 6’0” and approx. 225 \ 230 #s.) The 1LT \ Base seats, were noticeably less comfortable, at least for me. I’d also find the lack of the current trans. gear display on the HUD (3LT) to be annoying in a 1LT or 2LT – having to divert my eyes well down off the road, to the DIC display, below the Speedo & Tach. And the telescoping wheel allows me to adopt a more comfortable driving position.
 
I will once more mention that I noted ( and thoroughly enjoyed ) the very significant difference in acceleration feel between my current sedan (again, documented as a low 14s) and this 13 flat (or better) C6 A6. Because this is one primary reason for my lusting after the C6, and these drives met my (high) expectations. In my street driving, I can rarely even approach the handling limits of any car, as I always want to leave some measure of safety margin, to allow for the unexpected (for example: sand or oil on the road surface, an idiot move by another driver, etc.) even in (um) ‘spirited’ cornering. But I can ** ALWAYS ** manage a safe place to use WOT. Even if only briefly.
 
Yet, quite clearly, the C6 is much more than a very quick accelerating sports car. There was certainly no doubt in my mind after these test drives that the C6 is a thoroughbred: A refined, but very capable grand touring machine - as well as a an outstanding overall sports car. Exactly what I am looking for, right now.
 
So. I expect to order a 2007 – for delivery in late September to late October.
MX0, 3LT, CC3, Monterey Red \ Titanium.
 
Thanks to everyone here who has posted information & answered question.
 
Comments welcome.
