HVAC System Inoperative for a Drive Cycle, Poor HVAC System Performance

HVAC System Inoperative For A Drive Cycle, Poor HVAC System Performance In High Ambient Temperatures (Update HVAC Control Module Software)
2002-2003 Chevrolet TrailBlazer, TrailBlazer EXT
2002-2003 GMC Envoy, Envoy XL
2002-2003 Oldsmobile Bravada
Some customers may comment about no cold air from the heating, ventilation and air conditioning (HVAC) system during a drive cycle. This concern may occur at any time during the drive cycle and at any temperature setting. The HVAC system operation returns to normal after the vehicle has been keyed to off and restarted. This concern is intermittent and most likely to occur on hot days. This concern may be found on vehicles equipped with manual (CJ2) and automatic (CJ3) HVAC systems. Other customers may comment about poor HVAC system performance in high ambient temperature conditions. This concern may be present in automatic (CJ2) HVAC systems only. An HVAC control module software update was put into all production vehicles beginning in September 2002. Vehicles built in September 2002 and earlier may need this software update.
Update the HVAC control module using software available through GM Access beginning September 9, 2002. The update will be fully available October 7, 2002 to all dealers on TIS 2000 CD version 10. This software update addresses both the intermittent no cooling and the poor performance concerns. If the software update does not correct the concerns, perform the HVAC Diagnostic System Check and repair as necessary. If the HVAC control module is replaced with a part from GMSPO, make sure the module has the latest software update. The module may need to be updated even though it is a new part.

tblazed is correct. I had forgotten that the computer update was tried the first time I complained but it didn't do the job for me and they had to replace the cycling switch.

A question tblazed - Did you get the extended warranty? My first year of ownership is almost up. With zero problems so far (knock on wood) I am trying to decide whether to spend $1,000 for an extended warranty, although I really don't drive very many miles per year in this vehicle.

Thanks Tblazed and C.B for the A/C info.

No extended warranty for me. 3 1/2 years of no problems, just a few recalls. I am a do-it-yourselfer though, with service manual, so I can handle the less intensive repairs and the maintenance myself, usually for a lot less than the deductable. I prefer to keep my money where it's earning interest and dividends. A small percentage of people come out ahead on them, but most don't, otherwise there would be no reason for these companies to offer extended warranties. I looked over several "offers" that I received in the mail - the ones that are not GM list all kinds of things they cover that do not apply to the Trailblazer, and miss several others, what I consider very critical components an extended warranty should cover. However, if you're not inclined to repair things yourself and you can get the GM-backed extended warranty for $1000, that might be a good deal for you.

This is another good point that kills me about GM. Eliminating standard features that made the TB a liked vehicle. I can handle no light in the glove compartment, and I can handle no light under the hood. However, eliminate fog lights, eliminate a light above each door, and eliminate other neat items from this suv turns more people off. I am so glad I bought a 2004 instead of a 2005. I think that the 2005 model is not as good as the 2004. I don't trust the V-8 engine that shuts down four cylinders to save gas (it bombed with Cadillac if I remember correctly), I bought the EXT, so I want a V-8 in it. Having fog lights is essential to me, and to pay extra for them when I could get them standard the year before, no thanks. Also, I think cruise control was eliminated from the option package for 2005's. GM is shooting itself in the foot by trying to make their vehicles cheaper and cutting out the goodies that made the consumer come to them in the first place. I with you. I would have to get a great deal to get me to buy a new TB. The seats may be more comfortable, but GM has taken to many things away that I love in my 2004. I'd buy a used 2004 before I'd buy a 2005. That is saying something.
#16460 of 18329 extended waranty GM only
Apr 26, 2005 (6:43 pm)
My waranty is up in July on my 02-TB and I have 17k on it now. The GM majorgard waranty adds to you existing mileage. I am looking at 60 mo / 40,000 miles for $945.
with zero deductible. This will make my TB 8 years old when the wananty runs out.
I also do all of my own repairs but computer modules scare me and are expensive. For $200 a year, it is cheap piece of mind. Check out these internet prices on the link below. If you have less than 24k, it is cheaper

Apr 27, 2005 (8:41 am)
I'm dealing right now with a similar situation. My Service guy tells me that both lower control arms plus the sway bar need replaced, at a tab of over $1000.00. This is with 40,000 miles!!! Any suggestions on how I can approach this with the Service Manager. I plan on talking to the Factory Rep if I have to go that far. They say that there's "no way to just replace the bushings since GM only sells the lower control arms complete, no separate bushings". This is BS and I'm going to try to go to the mat on this one, even if I have to contact our local TV omsbudsman who tracks these issues.
Thanks for any council.
#16463 of 18329 Chevy TB vs. Mitsubishi Endeavor.... update
Apr 27, 2005 (3:31 pm)
For all the bluster and hyperbole about which is better or not, it's interesting to note that in 2004, Chevy TB outsold Mitsubishi Endeavor by about 8 to 1. Considering the vast dealership network Chevy has Vs. what Mitsubishi has, the Endeavor may be outselling the TB, dealer for dealer. Consider also that the Endeavor is rated higher than TB by just about every rating organization. For the power enthusiasts out there, the 270 hp TB at 4600 lbs is about proportional to the 225 hp, 4100 lb. Endeavor. The lower (by 2 inches) Endeavor has the same or slightly wider (approx.) front and rear track as the TB. The Endeavors suspension is a much newer design and as such holds the curves much better than the TB. There is no need to upgrade the stock suspension. The 225 hp. Endeavor feels like it has more available power at any speed, and the exhaust has a "growl" sound to it. Front seat leg room is a little shorter in the Endeavor but rear seat leg room is greater. The 315 watt Infinity stereo puts the power to the speakers, not the front of the radio, the front of the radio stays cool. The auto climate control works perfectly, set it and forget it. Doors and windows seal completely without needing additional foam stripping from the auto parts store. The back seats fold down with one motion, and don't hit the rear climate control console or the back of the front seats. Ground clearance for all you rock climbers is better than the TB, although I doubt anyone will take the Endeavor up a rock hill. My driving techniques are the same as with my old TB, so the mileage is about the same so far, about 20 mpg on the hwy. Mitsubishi recommends hi octane gas for the Endeavor. Running 89 octane so far has not caused any pinging or knocking. Steering is much quicker with the Endeavor, The number of turns lock to lock is less. The sunroof is probably 30 % larger than the TB sunroof. The head liner is firmly held in place and doesn't sag, as did the TB liner. The Endeavor comes with integral mudflaps on the front, again no trip to the parts store. Fog lights are standard with the Limited. Endeavor towing capability is about half that of the TB, and the hitch is not standard. The Endeavor runs at a slightly higher rpm than the TB did speed for speed, this may be why it feels like it has more power.
More to come as things happen.
