#260 of 762 2001 Tahoe engine noice A/C compressor
Sep 06, 2006 (8:56 am)
To begin thanks to all those who responded to my post. They were helpful - thank you. In conclusion to finding out the problem and solution to the grinding noise at 2000 RPMS on my chevy tahoe, it did indeed come out to be the A/C compressor. The tensioner for the A/C unit may have created the problem originally, as it did not allow the A/C unit to run correctly. As a result my compressor began to grind, with failure emenant. The damage had already been done, so the compressor needed to be replaced. In addition, the tensioner needed to be replaced to prevent future problems, and the system did need a new filter (metal scraps, Orifice A and valve. The seem also was drained of fluid to ensure to particles got past the filter. The good part, well sort of, was that with the help of your comments I was able to have a working knowledge of the problem to discuss with repair shops and part suppliers. As a result, parts from the dealers repair estimate could have been bought from the same dealer at their commercial parts dept. for much less. Example was the compressor itself. Estimate cost $576.00 - Commercial Parts dept. cost $387.00. Same Part! I also called Part suppliers (Napa etc.) and their prices for new top end compressors were about $380.00. I told this to the service sales man and he just said "really". In summary, I took my car away from the dealer, went to a specialist with all my new knowledge, quoted prices for parts and discussed tensioners etc. After his inspection, he determined what I said above, the same as the dealer, but without all the bull such as "having rear A/C increases the price tremendouly". In fact having a rear A/C system only slightly changes the compressor unit. It does not involve two units. The final price $850.00. This saved me $900.00 from the dealers price.
If I can help any one the all of you help me please let me know.

Thank you for letting us all know the end of your story, which was kind of a happy one when you was able to save a considerable amount of money.
So many people posting here don't say a word about it. The trail of a problem just stops. Often it might mean (I hope) that this forum gave some help in fixing a problem but so many don't bother letting others know what really happened.
Thanks to you!
#262 of 762 99 TAHOE NO START THIS AM
Sep 07, 2006 (5:45 am)
DROVE THE TRUCK LAST NIGHT, RAN FINE...THIS MORNING I GOT IN AND THE DOME LIGHTS WERE BRIGHT, BUT AS SOON AS I PUT THE KEY IN THE IGNITION I STARTED HEARING DIFFERENT CLICKING NOISES, LIGHTS WENT REALLY DIM, DOORS LOCKED ON THEIR OWN, THIS ALL WITHOUT TURNING THE KEY. THEN WHEN I TURNED THE KEY, I HAVE NOTHING...NO LIGHTS, NO SOUNDS, NOTHING. I INITIALLY SUSPECTED THE ALTERNATOR, BUT THE RESPONSE I GET WHEN I ONLY INSERT THE KEY CONFUSES ME, LIKE MAYBE I HAVE A SHORT SOMEWHERE. WHAT DO YOU THINK? ANYONE EVER HAD THIS PROBLEM?

I just learned my 2002 Tahoe has a disable system when the vehicle senses it is being stolen. Perhaps the system does not like the key you are using, esp if its a copy. Make sure you use the factory key to start and see iof that makes a differnce.

From: need411 I didn't get any replies so I fixed it the easy way. I traded it in on a 2005 Yukon. Let the dealer or next guy figure it out. Good Luck
#265 of 762 2007 LT leaking sunroof
Sep 12, 2006 (7:14 pm)
I noticed a few drops of water leaking from the sunroof of my new 2007 Tahoe. I took it to the dealer and they were able to reproduce the problem. I was told by the service department to be "normal" in this model as the sunroof has some kind of drainage. I tried to get an answer directly from GM and I am still waiting... Has anybody experienced similar problems?

Xavier it is not normal for any sunroof to leak. You shouldn't let them lie to you like that and demand that they fix your truck. My mom was considering getting an Armada until we found out all the trouble with the brakes. Then we decided to go with the new Tahoe and upon reviewing we are becoming very cautious in what we choose. Please keep us updated and at all costs demand that they fix your car.
#267 of 762 1999 Tahoe wont start--- Ignition modlue???
Sep 18, 2006 (1:33 pm)
I have a 1999 Tahoe with 134K. I went on a 500mi round trip and returned home. The next day I tried to start the car, motor turned over very well, strong battery and voltage, but it would not fire and has not since.
First- I had already replaced the fuel pump (and filter) with an AC Delco 3 months prior. The pump still sounded very strong, I checked the shraeder valve at the fuel rail and there appears to be plenty of fuel (50psi+).
Next step- I checked the spark figuring something wore out. Turns out I have enough spark to arc weld with.
Next- Poured gas in the throat (a fairly large amount) and the car sputtered to life for approx 2-3 seconds.
Diagnosis- We figured only when we absolutely flood the injectors with fuel will the car even attempt to fire, could this mean my injectors arent openning at the correct time? If so, we thought possibly replacing the ignition control module might fix this, does that control the firing of the injectors? I know there is a test with a voltage meter to check this, but I do not know the specific test.
Please help, any and all information would be greatly appreciated- I hate to just throw parts at a problem if someone else has a better idea!
