Technical service bulletin "03-01-38-019A" "SEP 04 A/C - Underhood Rattle Noise on Hard Acceleration" addresses this issue.
Here's what it says:
Some customers may comment about an underhood rattle noise heard on acceleration or a sudden loss of
A/C system performance.
This condition may be caused by liquid slugging of the A/C compressor. This condition may cause an
internal failure in the A/C compressor. The serpentine belt tensioner and serpentine belt may also be
Technicians are to check the A/C system performance and compressor operation using the following
1. Open the hood and inspect the A/C compressor for damage and to see if the compressor is seized.
Verify that the serpentine belt is not damaged or missing. If the A/C compressor is seized,
proceed to step 5.
2. Perform the A/C System Performance test. Refer to the Heating, Ventilation and Air
Conditioning (HVAC) section of SI. Correct any performance concerns or refrigerant leaks that
3. Inspect the vehicle for other possible sources of A/C compressor noise or performance concerns.
Refer to Corporate Bulletin Number 01-01-38-013 for more information.
4. After all other possible sources of A/C compressor noise or performance concerns have been
eliminated, only then should the A/C compressor be replaced.
5. Remove the A/C compressor. Refer to the A/C Compressor Replacement procedure in the HVAC
section of SI.
6. Inspect the transmission cooler lines for damage due to contact from the serpentine belt. Replace
the transmission cooler lines if necessary.
7. Install an inline A/C system filter. Refer to Corporate Bulletin Number 01-01-38-006C for more
information about A/C system flushing and filter installation procedures. An A/C system flush is
not to be done unless prior authorization is given by the GM Area Service Manager (in Canada,
the District Service Manager).
8. Install an A/C Suction Screen. Refer to Corporate Bulletin Number 01-01-39-003A for more
information about A/C suction screen repair recommendations and procedures.
9. Install a new A/C compressor. Refer to the Compressor Replacement procedure in the HVAC
section of SI.
10. Install a new orifice tube for the front A/C system. Refer to the Expansion (Orifice) Tube
Replacement procedure in SI.
11. If the vehicle is a 2003 model year Chevrolet Express or GMC Savana van, the vehicle may
require a new accumulator. Refer to Corporate Bulletin Number 03-01-38-016 for more
information. This bulletin refers to an updated design accumulator that may improve the
performance of the A/C system.
12. Install a new serpentine belt tensioner and serpentine belt if they have been damaged due to A/C
system slugging or an A/C compressor seizure. The serpentine belt tensioner may have broken
stop tabs and/or a missing front cap.
13. Verify proper operation of the A/C system.

I brought my new 2005 Yukon to the dealer regarding my AC vibration issue I spoke about in a post about a month ago
The dealer indicated that GM has agreed there is a problem, but they have not come up with a soution. They have given me a case # and showed me GM's Memo on the issue (which is from Nov 2004) and told me they will contact me when GM has a solution. I could post more info on the memo if anyone needs it
Another question for everyone
My driver side mirror seems to be auto dimming (looks like the inside rear view mirror in tint etc), but my passenger side mirror does not seem to tint/dim. Is this standard. I have a 2005 Yukon SLT. SO when you look at the outside mirrors at night, they do not look the same
Another intersting thought: When loading up my Yukon for a trip, I heard the air compressor going off too level off the ride height(I have Autoride) , Why doesn't GM have this compressor accessible to use to blow up items etc. My father in laws GM minivan has this feature. Just a thought

Aug 08, 2005 (5:39 pm)
I have a 95 Tahoe 5.7L with 140,000 miles. Sometimes when I start engine and place in reverse to back out of garage engine stalls. Some times when I am stopped at a red light engine stalls. It may go a week without doing this or it may happen 3 or 4 times a day.
Each time this happens it will immediately restart and run fine. Computer shows no codes (12).
I have replaced the coil, cap, rotor, electronic module in distributor, pickup coil, and ECM. Nothing has helped so far.
Anyone have any ideas?

I love my 2004 Tahoe, but it costs 50$ at least to fill it up !! I am sort of thinking maybe I need to trade to a smaller car, better on gas, maybe toyota avalon. any thoughts?

The difference in fuel economy will be more than offset by first year depreciation. Expect around a 25% loss in value from your purchase price.
It is something that many do not consider; the big incentives in rebates, employee pricing, and subsidized interest rates can kill the value of a one year old vehicle. I can use our '04 Yukon as an example:
Price: 31500 before taxes and fees.
Value: 23687 Private party per Edmunds
So, assuming I can get top dollar, thats a $7813 loss after 15 months.
An '05 equiped the same as the '04 can be had for about $32K, or about the same as the '04 was new. And get the full warranty.
Now, for those of you who might not have caught something here, you might note that the '05 actual cost, even with rebates and "employee discount" is more than the '04. That is because GM is nothing if not a master at number magic. By raising the employee cost, they were able to run the big ad campaign and still make the same or better money on the vehicle.

Well, if $50 is the magic number....I hate to inform you that it could easily cost almost as much to fill an Avalon. 18 gallons at todays average $2.429 for 87 octane will run you $43.72. Of course the cost of a fill-up isn't exactly a good measure of your fuel costs. I have a diesel truck that holds 90 gallons.....
Now...if you want something that gets better gas mileage that's another story. An avalon is a very nice car, particularly the new ones. You'll probably average about 25mpg instead of 15mpg with the Tahoe. So if you drive 15,000 miles per year, that's a savings of about $1,000 per year. Not likely to make-up for your terrible depreciation hit you're going to take by trading your Tahoe.
If you're planning to buy a new vehicle anyway, then this would be a good time to consider something more reasonable on fuel. Particularly if you really have no need for a full-size SUV, which appears to be the case.
It's not easy to save money by trading vehicles, particularly just for gas savings. Maybe if you drove 25,000 miles per year and would take a Civic over a Tahoe.

Hmm, shoulda bought an Avalanche.
'03 MSRP $34k, paid $24k
Current Edmunds trade-in 18,827, private seller 20,315.
only $3685 loss in 31 months. (Been offered $18500 to 19500 trade on loaded '04s selling below Retail)
#5427 of 6471 Re: axle ratio [sebring95]
Aug 09, 2005 (10:59 pm)
The reason GM charges $100 for the optional axle is to discourage people from buying them. If GM sells too many of the higher numeric axle ratios, it will hurt their CAFE numbers. So, by charging for the optional axle, you will only get it if you really want it. I found there was a major difference in acceleration feel between a 3.73 vs a 4.10 in 2001 on a 4wd Suburban. The 4.10 felt much better. This combined with the towing I do, made the decision very easy for me. No regrets at 65,000 miles.

Just a thought have you tried to replace the starter solenoid. The symtoms your describing are signs of a bad starting solenoid. Also plugs and cables but if you don't have hesitation during acceleration I don't think the plugs are bad.
