Here's the changes that have been documented in some form or another:
What's New For 2003
A whole lot of changes are coming for the 2003 Avalanche. The entire Chevrolet truck line up is getting a major interior facelift. The Silverado will get an Avalanche front clip and the Avalanche gets an exterior make over with darker cladding (pictured to the right). Here is what's new and what's gone in 2003.

Although the North Face, Z-66 and Z-71 packages are not available on the 2500 series, all other option changes carry over the beefier Avalanche.
The engine and transmission lineup remains the same in 2003. Horsepower and torque numbers also remain the same. The automatic transfer case is suppose to be improved and will offer slightly better gas mileage over the 2002 model. No information is available on interior colors but the headliner is now listed as being "slate" instead of "neutral" in color. There is a strong rumor that the North Face Edition interior will no longer be green with orange trim, but this is not confirmed. New pricing is not available at this time.
Ordering A 2003 Avalanche
Chevrolet dealers are accepting orders for 2003 Avalanches at this time although dealers do not have pricing available. Lead time is running eight to ten weeks with first delivery estimated on August 5, 2003.
#235 of 534 Avalanche Smoke Problem
Aug 03, 2002 (5:12 am)
My 2002 AV was blowing blue smoke upon start up. I brought it into the dealer who advised there was a GM technical bulletin out advising them to take the engine cover off and view the lifters as the engine was started. If oil poured out the lifters needed to be replaced. If not a newly designed PCV valve had to be installed. I was advised that a new PCV valve was installed as the lifters appeared to be fine. When I picked up the vehicle within a few miles white smoke began to billow out of the exhaust and the engine rattled. I called the dealer who towed the vehicle in. I was advised after a week that the newly desiged PVC valve was the problem and when the old one was reinstalled no white smoke came out, however the blue smoke still was emitting upon start up. I was also advised that the Valve seals had been severly damaged and needed to be replace. I have advised the dealer in Fredericksbug, Va that I want the vehicle operating as designed (no blue smoke)or a new vehicle or engine. My AV is 6 months old with 12,000 miles
#236 of 534 Sunroof problem
Aug 05, 2002 (3:23 pm)
My husband has a 2002 1500 Z71 which is almost a year old now. Just recently, we have had problems with the sunroof closing. This seems to only happen if the sunroof is fully opened. It tries to close but seems to be hung up. He has eventually gotten it closed by reaching up and grabbing it--once it reaches halfway it closes with no problem. Anybody else had a similar problem???
#237 of 534 Avalanche Smoking at start up/ Seat creaking !!
Aug 31, 2002 (8:29 am)
YES it's Fixed .......I think !!!! The cure for the smoking problem was determined to be the PCV valve and was replaced, the dealer has requested an appointment to check the consumption while it's in for the seat mechanism replacement for the creaking seat........ As far as i can tell the smoking is gone, oil consumption is down and it should be ok........BUT......I still hear a spark knock when i crank it up in the morning probably due to fouled plugs while the smoking was going on, i'm asking for a spark plug replacement and one more check on the valve guide seal and valve replacement bulletin to see if it was done properly. Some postings i have read say the bulletin says replace valves and seals and the pcv valve. as far as i know the only thing done to mine was the pcv valve was changed.
thanks for all the postings it really helps to deal with service advisors who claim they never heard of such problems with av's in there experience. HUH !!! Don't believe it !! There are to damn many of these av's blowing smoke to not have heard of it. And it's amazing after showing these people the copies of the postings that all of a sudden my av is fixed....He he he !!
#238 of 534 Leaking Avalanche...possible solution.
Sep 03, 2002 (6:13 pm)
Read many post on the avalanche leaking even before I bought one. I now own one anyway. I have discovered something about the midgate that MAY be a solution to fixing many of the leaks encountered on the avalanche. When I first got the truck I checked for any wetness of signs of any leaks and found none. I drove the truck for a few weeks before actually converting it due to busy scedule. Before I converted it I inspected everything....every joint the midgate made with the surrounding seals, the window etc. Everything was nice and tight, and the window and the midgate bar had no play at all. I took the truck to the drive in and while there converted it so that we could hear the radio better out the back. I converted it back in the dark and all SEEMED to go well. The next day however I inspected the midgate and all the seals. There were small gaps around the edge of the window/midgate bar on the out side....I though "well shucks...looks like water could get in there!" I proceeded to check all the things I checked the day prior. I opened it back up and then closed it up again. Guess what, still had gaps. I looked closely at the gaps, and the 2 at the back window would leak water into the cab if water were to hit them. I followed the trail and the water would seep into the back down the "sides of the midgate" and wet the carpet and floor. Now I thought this odd....why were they sealed fine from the factory but after I converted it, there were gaps that were potential leaks? I figured it must be something I was doing wrong. Well guess what, it was.
My inspection prior to opening the midgate had tight seals and the midgate bar and midgate had no play, nice and tight as I mentioned. After my twilight conversion and even several other conversions while inspecting and following leak trails, I discoverd this. When I closed the midgate, and put the back window back in, I noticed the back window now had some play in it, it was not tight. I'll bet it would even rattle while driving. I also noticed that the midgate bar also had some play in it. It was tight before. I assumed that maybe the latches came out of adjustment and this left the midgate and back window "loose". Well being the optimist I am, I figured that it could not have just "popped out" of adjustment so I took the old fassioned approach....I opened the midgate, then I slammed it shut harder than I had been doing in previous closings. Guess what? The midgate bar no longer had any play, same with the window...tighter than...well you know......it was tight! The gaps on the outside at the bottom of the rear window were gone....and it passed the water test.
So folks, before having the dealer replace seals or adjusting anything(which since they do not have experience doing it much can make your problem worst) check the seals and the midgate bar and midgate for "play" and check for gaps around the seals on the outside of the back window, then slam that darn midgate a good one (don't slam it into next week, but don't be a wuss about it either) and then re-check. The midgate bar and midgate should not move when you tug on it. This may indeed fix you leak problem.
Hope this helps.
#239 of 534 mrpush, thanks good info

(from a potential new Av owner - I'm looking). On Sunday I was nosing around and found an Av with the tailgate unlocked. It also takes a pretty healthy slam to close them. I hope that's because they seal tightly.

The owners manual states that you have to give it avery firm closing effort as there is a big seal. If you use google and do a search for Avalanche you can find a club that has a ton of information on it including a owners manual for download.

#243 of 534 4-Wheel Drive Concern
Nov 20, 2002 (6:51 pm)
HELP! I've used my 4-wheel drive option twice, once in the parking lot at the dealer and again today...some 40K miles later. Works great as long as you drive in a straight line, try turning and it's like applying the brakes...this happens only to 4-Hi and 4-Lo , works great in Auto and 2-hi. Fluids are fine...any suggestions??
