I have a 03 Tahoe with 5.3 L. I get around 18 mpg hwy. I bought it used with 86,000 miles. Warranty claims were instrument cluster replace, fuel tank fuel module replace,intermediate steering shaft replace, right front diff shaft seal replaced,pressure cycling switch replace, transmitter of rear door compartment lock replace.
I like the power and the ride, and ease of parallel parking, though there are different suspensions available, I tried some pretty rough riding Tahoes before I bought this one. It does have some play in the steering while turning corners around the block but not while driving on the highway. This may be the way the steering box is set up, but is not a major issue. I am concerned about the reliability of the electronic modules and dash cluster though.
I also have a 03 Silverado short box with the 8.1 L and it gets the same mileage. The last I checked was 33.5 liters for 150 miles. 1 liter is about the same volume as 1 US quart. Both have 3.73 gears

I realize your original message was posted a long time ago, but I want to know if you ever had any resolution to the front end shaking? I have a 2000 Tahoe LT 4WD and we have experienced a tremendous front end shaking at highway speed, just as you described, but the strange thing is that it has only happened 4 or 5 times in the last 12-18 months. Chevy can't find a problem, so we took it to an independent mechanic, and they can't find the problem either. Of course, it never happens when they take it for a drive. Please let me know, I get a little nervous driving the car on the highway because of this.

Is your problem like regina1 explain, i.e. it shakes after you hit a bump?
 
If it is the next question is, what mileage do you have and have you ever changed the front shock absorbers?
 
Also, do you have oversize wheels on your truck?
 
Does it feel like you cannot stop the truck if you hit brakes right before or after a bump on road?
 
All of the above points to direction of inadequately working shock absorbers.

Hi Arrie, thanks for the response.
Yes, it happens after we hit a bump. I have just under 65K Miles (not bad for 9 years old), we have Kelly Safari Tires P245/75R16, and we have NOT changed the shock absorbers.
I haven't really thought about the stopping that you mention before/after hitting bumps, so I would have to say I don't recall a problem stopping.
-One thing to note that might be helpful to you... once when this happened, 2 men driving almost next to us had us pull over because they saw the severe shaking and wanted to look under the truck to make sure the front wheels weren't going to come off! They did a quick 'by the side of the road' check, and didn't see anything unusual. This particular time we had just gone over some bumps, and we were in a slight turn to the right. Although this has also happened when we are going straight.
Although this has only happened a few times, I have this fear that the wheels are going to come off when I'm on the highway! Is that even possible?
Any thoughts? Thanks again!

It really sounds weird if shaking is so bad that people in the car next to you can see it so severe they want to stop you for inspection...
 
Again, it sounds like your shock absorbers are all gone. For a 9 year old truck you should change them anyway. And they are not really that expensive.
 
Do you think your tires are in a good balance, i.e. do you feel any kind of vibration in the steering wheel other than when shaking goes very bad?
 
It could be that when you hit a bump it gives the suspension spring system an impulse that is then kept vibrating by off balance tires.
 
How about tire wear? Do they wear evenly. i.e. no outside or inside edge wear?
 
The big shaking should be taken care of with new set of shocks and tires should be in such balance that you feel absolutely no vibration when you drive.
 
You can test shocks by applying weight on front bumper (same for rear). When you remove the weight the truck should raise up and then slightly down and stop at its normal resting position. If you see any movement up again your shocks are to be replaced. i.e. shock absorbers should stop the up-and-down movement at 3/4 point of the vibration cycle and not start up again.

Just had to replace my drivers' side front window this last weekend. Purchased the motor on-line. Same motor will work for the front or rear window on same side. It only cost me $47.99 out the door, and my neighbor installed it for me. It took him a few hours but it works as good as new. It is slightly louder than the other motors, but nothing to complain about.
 
Hope this helps!

I have a 2003 Chevy Tahoe with 81000 miles on it. The heater and a/c fan only works on the highest speed #5. How do you repair this problem?

Not sure if they still use the resistor network for speed control on all but the highest or not but if they do, it sounds like there is a open circuit in the common line to the resistor network.

2003 Tahoe AC issue by kmitchell3
May 22, 2009 (4:35 pm)

I have an 03 Chevy Tahoe Z71 -- the ac seems to work but the fan doesn't blow at ll unless you are going down the road pretty fast it will blow out some. I checked the BLOWER fuse and it was fine. It seems to me that this might be a wiring issue. Does anyone know where the ac fan is located in the engine so I can check the wire going to it? Also, what other things can I check myself before having to have it looked at by a professional. Thanks
