Paisan, I'm sure you'd love this stuff! Wish I could try my trailblazer out there.
These are the only digital pics. Scans are yet to come.

I believe that the vehicle as built does meet CA standards and all that the CA emissions involves is a sticker (and possibly GM paying the State of CA some fees for testing etc).
I called up GM Buypower and they said that the Dealer Business Center should be able to help the dealer on how to purchase the appropriate "upgrade" (I think the code is YM6).
The dealer claims that he has been unable to get accurate information from his DBC on how to do this. Is the dealer BS'ing me or is it a difficult process?
Any one out there have any experience with this?
I read this board, but if you want to take it offline, please email me directly at anavision@usa.net.
THANKS IN ADVANCE!
could be the sensors in the HVAC, but my guess is that your system needs the latest reprograming and update as mine did back in Jan.
I got nothing but cool to cold air when auto temp set to anything below 87.
now I just hope the AC works okay!

Thanks to Tim Lauro doing his homework and superb website, I was able to download most the TSB's before getting locked out. Got the tailgate gasket installed and the mirrors replaced(should have the seen the service manager's mouth gape open when I provided the part number and TSB number for the gasket.)
Once he knew I was armed with the info, he went ahead and upgraded the computer with the latest software and was much more accommodating with my requests. I now have a good relationship with the dealership. The Envoy now feels more responsive and smoother. Cold start acceleration and noisy fan was never a problem. If anything, the I6 feels like it has a tad more snort when it is cold.I can't wait for cold air induction and maybe a less restrictive exhaust.
As a side note, I recently came through a toll booth the same time as a Navigator, and he wanted the same lane I wanted....I got the lane.

I'm supposed to go in next week for the rear gasket upgrade and a new hatch seal and will pick the brain of the Tech who works on my TB. He know's his stuff and is a straight shooter.

'02 TB LTZ
Left the vehicle running for quite a while and used it for a little on Saturday. Satuday night, turned off all the lights in the garage and got in to see if anything was left on. Nothing. Then tried to start it on Sunday and it started. On Monday, checked to see if there was still power and there was.
Then, Tuesday morning, the wife needs to go somewhere with the kids, tries to start the car (there was power to the dash, unlike Saturday), but the car won't crank up and start. AAA to the rescue again.
So, we dropped off the Envoy at the dealer yesterday, they kept it overnight to see if it would drain again, and now I'm without a car since she needs my vehicle today.
Needless to say, she is frustrated to the point that she is seriously considering trading the vehicle in or selling it. The car has 15,000 miles in a year of ownership and it's been to the dealer for repair at least six times. I can't say I blame her for being frustrated, but we did decide to buy a first year model, so we should have known these problems were possibilities.
Anyone else out there have their Envoy just die on them in their garage with no apparent reason for the battery to drain?
My .02 cents worth

BTW, I stopped visiting this forum for a while after GM finally told me that they were going to get a "prototype" gasket to fix the tailgate paint problem. (After a two month wait instead of the 10 days I was promised, they finally got and installed the part.) It's refreshing to see that someone from GM has decided to join in and try to lend a helping hand.
Thanks!

I'm keeping my fingers crossed.
They also installed the infamous tailgate gasket
(it SHOULD have been there from day 1), update some computer codes, and replaced the accesory drive belt (squeeked).
Unfortunately they didn't have the parts for the fuel line recall so it will be going in again soon. That will give me some time to see if anything else goes wrong.
All and all, a very disappointing start to my new vehicle experience. The dealer was not at fault though. GM could learn something about expediting parts for undrivable vehicles.
As far as the BMW post: be careful what you wish for. The BMW SUV has has 7 or 8 recalls in it's short life!

02 Bravada with 3500 low miles (purchased 10/01) pulled the dreaded delayed acceleration trick on us yesterday - no power at all and a roar from something other than the engine. Up to now, I've had most of the minor issues which have been fixed without too much pain by the dealer leaving me feel fairly confident in the vehicle.
It seems like the 3000 mile barrier is when some of the major problems start to surface with the engine and/or computer controls.
As with most of you, I'm armed with TSB's and part #'s. Without them, my dealer has been plead the 5th. With them, things get fixed.
# ID Description
1. 12575262 new software to correct case learn issue
2. 12575727 new calibration to correct problem
3. 12575341 new calibration to address delay in transmission downshifting
4. 09351581 speedometer calibration
5. 12576361 enhance ev fan calibration for cooling fan noise reduction
6. 12571574 electronic throttle control calibration
However, after reading the "all or nothing" posts from "gator38" and "medolark" #5538, and looking at the lack of (update detail) on my workorder after the work was completed, I think the specific update #'s are insignificant.
I did however insure their TEC tool was at the appropriate level (thanks to gmdrone) post #5516 were he said: "If you have had the PROM reflashed,make sure that they use GM-VIS TIS 2000 Version 8.5/2001"
The only difference with our two LTZ's is build date. My build date is 06/01 (yes... I ordered early. When I jump in its with both feet :-) )
I am on the 3rd tank now am still at 16.+. Hope this helps.

PCM update 12575341
I had also been very interested in either the Envoy SLT or the TB LTZ, and wanted to hear from any people currently under lease, what the leasing costs were. Any comments on how satisfied you are to date with your trucks would also be appreciated.
Thanks in advance...
I have an Envoy, but I assume they would be similar, but not sure. Like you, my security light does not automatically blink when I remove the key and open the door, even though the Envoy manual also says it should (as a reminder to activate it). It won't flash until I arm the system by pressing "lock" on the remote with the door openand then shutting it. If I lock the door with the remote with the door already closed, the security light will come on, but not flash. In either case, the security light will go off in a few seconds once armed. So it sounds like yours works in this same way, but maybe some TB owners will confirm. I'm not sure why our manuals says it blinks "as a reminder" when it automatically arms anyway if you use the remote or the driver powerlock.

They seemed amenable to fixing everything except for the reprogram on the PCM. They fought me saying there were no dtc error codes stored and so they wouldn't reprogram without error codes. I was however informed that the codes are only stored for 50 key inserts and then lost. I don't think I've had the problem the last few weeks so previous error codes may have been lost. Anyway I tried to suggest that if the software was updated and improved that it seemed logical to upgrade the PCM anyway even without the codes. They did not want to do this. Is my logic flawed? If my computer software has an upgrade I usually install it, why should a car computer be any different. If things have been improved and fixed with newer software, why shouldn't I get the update. I was also hoping that the upgrade would also help my mileage (13-14 average mixed town/highway). By the way, no parts were in so everything had to be ordered and I have to take it back in. They seemed to concede that they might reprogram the PCM with the other repairs.
My one recourse it that the President of the Dealership is my patient and would probably help me out if I really couldn't get this resolved. I'd rather not bother him however.
Right now this is a minor annoyance to me and I'll probably wait until I take the vehicle in to have the license plate gasket installed and ask them to reglue it while it is there. I might even decide to do it myself since I think loosening the inner liner on the fender would provide enough access to get a tube of adhesive in there.
My advice is to never put a dime as a down payment. See the leasing section of my site. If the payments are pushing your budget, you need to buy a less expensive vehicle.
Again, zero cap cost reduction. Just put a Security Deposit...may be waved if you've leased from the lending institution before...make your first payment of course and pay any taxes, etc...perhaps only pay the Aquisition Fee..but that can be rolled into the lease too.

Unfortunately my fix only lasted about a month and then I had several repeats. Of course now that I want to take it in again, the problem has disappeared. Been another 4 days without any fan noise or acceleration problem???
Maybe before you get it reprogramed it would be interesting to find out from the others on the board that have had this done, who has had long term success. Mine is about 5 weeks old, failed again after four weeks, but now seems to be random. Everyone else???
Obtain the latest engine controller calibration information for your vehicle simply by entering the vehicle's 17 character Vehicle Identification Number (VIN).
Vehicle calibration information includes any 1993 or later model year GM vehicle equipped with a reprogrammable engine controller (PCM or VCM).
Can you please post the web-site where you can enter this data??
Thanks.
Blown Powertrain Control Module (PCM) - within the first month we were stranded on the highway when the PCM was fried. We got a Check Engine Soon warning but the folks at On Star said to look into before a week or so. Throttle Control Module and PCM module were replaced and reprogramed. Similar problem a week or so later. Seems there was a voltage surge problem from the Air Compressor from the rear suspension system. An electrical filter was added and this problem seems to be fixed.
Fan Roar on Cold Starts - intemittent problem. Dealer says this is "normal". Our PCM has been re-programmed sevearl times in the last few months so the early TSB that addresses this problem doesn't seem to solve the problem. Since this problem is also tied to high RPM and reduced engine power, this cannot be "normal".
Malfunctioning Memory Mirrors - dealer replaced memory modules first and then the mirrors. Still not fixed. GM says a fix should be available by the end of May (sure hope so, I'm afraid that we'll wear out the mirror adjust switch from overuse).
Rain Sensing Wipers - would come on during sunny days. Dealer intitally said this is normal to "let you know that you are in the rain sensing mode". Later admitted there is a problem and replaced both wiper motors. Still had the problem. Replaced the moisture sensor and the problem seems to be solved.
AWD Transmission Surge - intemittent problem. Most of the time a takeoff from a dead stop is smooth, but sometimes there is a hesitation and sudden surge as if something slipping finally takes hold. Dealer did a "re-calibration" that did not fix the problem.
There were several other minor problems: L/H door handle fell off, loose sun visor, loose nut on air inflator valve, etc.
Bottom line. Nice design, lousy quality.
I took it to the dealer last Thursday, and was told they would need it until Friday (waiting on parts).
On Friday, the dealer called, saying the ring and pinion needed to be replaced due to a factory installation problem. However, they didn't have the parts. In fact, there weren't any parts in all of the Dallas-Fort Worth area.
Apparently, there's a process the dealer can use to notify GM when they have a vehicle down due to parts availability. This initiates a nationwide search for the needed parts.
Monday, the dealer called saying GM would have to "make the parts", and it would probably be next week before they would arrive.
Tuesday at 4:00 pm, the dealer called saying my Envoy was ready! The dealer said he was surprised when the FedEx package showed up Tuesday morning with the needed parts.
The whine is gone. Life is good.
I am talking about 1200-1300 versus the normal 700-800 when the engine is warm. Is this what you are considering high, or is the engine really racing? I am not noticing any delayed acceleration.
I wouldn't say that the noise I am experiencing is a 'roar', but the fan is definitely running.
The reason I ask, and I am not trying to downplay the issues folks are experiencing, is all of the cars that I have owned have had an increase in RPM's on cold start-up until the engine reaches operating temperature.
If I am way off-base, let me know, and I will shut my pie-hole.

If you ever experience the "Roar" from the coolant fan, you will know it. It sounds as if it is an airplane is ready to take off.
The coolant fan is just another of the many items that are controlled by the PCM. Micro-processor controlled devices are great .... if the programming is correct.

This is the only significant problem I'm having at 4000 miles.
The noise at 50, whining, is distinctly a differential noise, but the growl felt in the body of the truck at 58-62 appears to be exhaust resonance or engine harmonics, transmitted thru the engine mounts or of course the exhaust system.
THANKS
