#8700 of 18329 A couple of TSBs that may be of interest
Nov 12, 2002 (5:30 pm)
A while back there was a lot of talk about GM installing the roof rack rails backwards. Here is a TSB that addresses that. Also, one that addresses my gripe of the indentation left in the rear leather seat when it is folded against the auxillary power outlet...
Proper Position and Installation of Roof Rack Cross Rails to Reduce Wind Noise
2002 Chevrolet and GMC S/T Utility Models (Trailblazer, Trailblazer EXT, Envoy, Envoy XL)
2002 Oldsmobile Bravada
Some of the above vehicles may exhibit wind noise related to the roof rack. In an effort to reduce wind noise, Engineering has identified a specific position and installation for the roof rack cross rails.
Beginning on September 6, 2001 the Trailblazer, Envoy, and Bravada were built with the roof rack cross rails installed in the reverse direction (arrows towards rear of vehicle).
Early calendar year 2002 the Trailblazer EXT and Envoy XL were built with the roof rack cross rails installed in the reverse direction (arrows towards rear of vehicle).
Early calendar year 2002 the directional arrows were removed from the cross rails on all models to eliminate any confusion as to which direction is correct.
It has been found that some dealers are changing the direction of the cross rails thinking they were installed incorrectly.
To obtain the optimum position and installation of the roof rack cross rails that produce the least wind noise, use the following procedure:
If the cross rails have directional arrows, they should be installed in the reverse direction (arrows toward rear of vehicle). Remove the cross rails and rotate as necessary.
If the directional arrows are not present, installation can be verified by checking the location of the cross rail eyelets. When installed in the reverse direction, the cross rail eyelets will face the rear of the vehicle. Remove the cross rails and rotate as necessary.
Once the specified direction has been established, adjust the position of the cross rails, so that one cross rail is positioned at the rear most end of the vehicle. The other cross rail should then be positioned at approximately midpoint of the rear door glass.
Interference with Center Console Rear Auxiliary Power Outlet Cover and Rear Seat Cushion (Replace Rear Auxiliary Power Outlet Retainer and Cover)
2002 Chevrolet TrailBlazer
2002 GMC Envoy
2002 Oldsmobile Bravada
Built Prior to May, 2002
Some customers may comment on an indentation mark or, in extreme cases, a puncture of the rear left seat cover. When the left rear seat bottom is raised and the seat back is folded down flat, the seat bottom rests against the back of the center console. The auxiliary power outlet cover, located on the back of the center console, contacts the seat bottom. If enough weight or pressure is applied to the seat bottom in this position, the auxiliary power outlet cover may leave an indentation or possibly damage the seat cover.
The auxiliary power outlet cover has a raised finger tab. This raised tab on the cover may cause the condition.
A new auxiliary power outlet retainer and cover assembly has been developed to correct this condition. The new cover has a smooth surface and no raised tab. Install a new auxiliary power outlet retainer and cover on the affected vehicles. Use the following procedure and the part number listed below.
J 42059 Cigarette Lighter Socket Remover
Remove the AUX PWR 1 Fuse 46 (20 amp) from the rear fuse block.
Open the auxiliary outlet cover. Insert the J 42059 into the outlet and position one side of the "T" portion of the tool into the square tab at the rear of the outlet. Then position the opposite end of the "T" into the opposing square tab.
Partially (about half way) pull the outlet straight out of the retaining ring. Use your fingers to aid in guiding out the outlet.
Using a flat-bladed tool, remove the rear auxiliary audio/heater controller unit above the outlet and let it rest. This will aid in gaining access to the connector at the back of the outlet.
Turn the outlet one turn counterclockwise to access the outlet connector locking tabs. Through the controller opening, use a small flat-bladed tool and disengage the locking tabs of the connector and disconnect the connector.
Disengage the retainer ring and cover from the mounting hole by turning the retainer ring/outlet assembly back and forth and lining up each of the three tabs on the retainer to the top slot in the mounting hole. Do not force the retainer ring out.
Pull out retainer ring and outlet as an assembly.
Using the tool, push down in the outlet to release the retainer from the outlet. Remove the retainer ring and cover from the outlet.
Remove the tool from the outlet.
Position the new retainer ring and cover to the mounting hole.
Index the retainer ring cover top notch to the slot in the mounting hole.
Install the retainer ring and cover by pressing the retainer ring into the mounting hole until fully seated
Position the outlet in the retainer ring and partially push the outlet in.
Through the controller unit opening, connect the electrical connector to the back of the outlet.
Press in the rest of the outlet until fully seated.
Install the auxiliary audio/heater controller unit back into place.
Install the AUX PWR 1 Fuse 46 (20 amp) into the rear fuse block.

#8702 of 18329 drive train characteristic
Nov 12, 2002 (7:11 pm)
kgoward: ask your dealer if they will initiate a recall to program the vibration characteristic into the rest of the tripletts out there, since mine doesn't have it now.
What a line of bull.
I am starting to feel bad for some of you who are stuck with dealers like this one. I wonder where they received their certification?
#8703 of 18329 2003 Bravada
Nov 12, 2002 (10:31 pm)
BTW, the cargo shade was an extra cost option on the 2002 Bravada also. It was part of an option package in 2002. In 2003, all the components in the prior option package are individual options. However, their extra cost for 2003 is or was equal to their cost within the 2002 option package.
That not-withstanding, GM has a two pronged effort at increasing their margin on the 2003 Bravada. Besides the de-contenting effort already noted, the base MSRP has been raised at least twice (second increase was posted on their wed site on 10/19/02) for the 2003s. They have also started to raise the list price of some of the individual options (e.g., the polished wheels were increased $100 in mid-October). The sum total of these increases far exceeds the current rate of inflation in the economy, so I can only assume they are intended to recover some of the margin lost to Cash Back rebates and Zero Percent financing. The good news, at least with the Bravada, is that dealers seem willing to sell at invoice w/o much of a fight.

They have to do something to make up for all the losses in their pension fund!
#8705 of 18329 Flickering headlights
Nov 13, 2002 (7:17 am)
Maybe my luck is beginning to run out... seems like I have seen something on this here before, and last night noticed for the 1st time my TB did this: Backed out of the driveway into the street, put it in "D" and the headlights flickered noticably a few times. Maybe 10 or 20% reduction in brightness when flickering. Nothing else seemed effected. After that all OK. Of course with it doing it only this one time so far I did not notice the dash or other lights flickering. Anyone else experienced this and has it been fixed? What was the fix?

There wouldn't be a shortage if GM had not been pilfering every nickel above statutory requirements over the years.

In response to #8391, I have posted here my unique vibration / resonance exhibited by my '02 TB with 3.42 at 57 to 63 MPH. Finally took to the dealer and is there now. I demonstrated the symptom for the service mgr. and he agreed it was not normal. He did call the GM technical service for assistance. They were aware of it as others have called in. He did the trans. reprogram - no help, and also swapped out the aluminum driveshaft (std. in '02) for the steel driveshaft (std. in '03)- no help. Now waiting for revised rear springs which were revised for '03 with a insulated coating of some kind. Other than that, they are not sure what else to check. The '03 (identicaly equipped) on his lot exhibited the same symptoms. It may also have something to do with the harmonics in the exhaust system. Any idea's?? Thanks.
#8708 of 18329 Headlights flickering
Nov 13, 2002 (8:13 am)
Did you back out under a streetlamp or some other source of bright light? If the daylight sensor was triggered the headlamps will be set to a lower brightness. There is a time delay to keep this from happening but I suppose it can happen.
#8709 of 18329 2002 Bravada with Trans Troubles Identified and being fixed
Nov 13, 2002 (8:22 am)
Well, the Dealer finally got the trans to slip for them. So they believed there was a problem and finally investigated. Turns out the whole trans was smoked after 6500 miles. I believe it has to do with the bulletin "01-07-30-043 A/T - Slipping/Missed Shifts Diagnostic Tips" that deals with 4L60 Auto Trans problems.
So they're fixing it.
And I think with that, I'm done. All the quirks are fixed.
