    Thanks for the advice. I actually got to look at it today. The fan is loose where it is bolted to the wheel assembly. Is that the fan clutch assembly or just a bearing assembly? I can wiggle the fan by the fan blades.

    I will be dropping it off tomorrow at the dealer.

    Unless you checked to see if the bolts are loose,prob the fan clutch assembly.

    I didn't have time to replace it, so I took it to the dealer - It was the water pump. All is well again...

    Thank you all for the feedback.
  • I've been noticing that the top of my left shoe is wet after driving my 2003 Envoy. It looks like dirty water (from melted road salt/snow crud).

    Anyone else ever experience this? Where is the leak coming from?

  • Seems that since I had the Transmission rebuilt my 4x4 switch is jumping back and forth from 2wd to Awd as I drive. I can feel the slight clunk as it transfers back and forth into each drive mode. I had the switch replaced once probably around 40,000 miles or so (120,000 now). Anyone know what causes this and what needs to be replaced? As I recall it is something in the transfer case that causes this to happen?
  • :cry: sigh. My very reliable, very low maintenance '02 Trailblazer with 175,000 miles died on the way home from a work trip last week. It doggedly traveled 5 miles and up a steep mountain with no oil pressure to a service station near Shady Springs, WV to make sure I got somewhere safe and warm. The engine seized just as I threw it into neutral pulling onto the lot. It was 20 degrees, 9:00 at night, with the wind blowing hard. I'm gonna miss it.

    I never realized how emotionally attached I was to the thought of snapping it's 200,000 mile pictures and showing them to everyone. I guess it just won't happen now.

    Anybody doing anything interesting with broken Trailblazers these days? Engine swaps?
  • burdawgburdawg Posts: 1,524
    I think with that many miles I would just let it go. We just turned 60K on our 02, hope we get another 115K out of it!
  • Well let's see. Hows the suspension? Does all the electronics work still? Brakes in good order? No body damage? If you have minimal problems then just get a couple estimates and replace and or rebuild the engine. Or you can go down to your local dealer and start making those strokes on another depreciating asset. Yeah it will smell all nice and the paint will shine but it will be just another used car in a couple years. I will never I REPEAT never buy another brand new car as long as I live. Let some other fool pay full price then swoop in there after a couple years and take it for what it's worth. Has anyone ever bought a used car based on Kelly Blue Book to have it depreciate by 25% only after 3 months? Well that's what happens on brand new vehicles. The big three will be just like the American TV manufactures. Just a name that we once new. Pay a couple grand for a new engine drive it until 2012 then consider getting another car.

    Just my $0.02
  • I am in need of an upper liftgate molding (it has the 3 brake light in it) for a 02 TrailBlazer LT EXT. Any year from 02 to 06 will fit. If anyone is parting out their old TB or know of a good place for body parts (used) I would greatly appreciate it.

    Thank you for your time,
    Matt Myers
  • >>Hows the suspension?
    Meh~ Not bad considering.
    >> Does all the electronics work still?
    Yeah, needs speakers.
    >> Brakes in good order?
    >>No body damage?
    >>If you have minimal problems then just get a couple estimates ... Pay a couple grand for a new engine drive it until 2012 then consider getting another car.

    Yeah, but it was due for replacement this year. I was hoping someone would say "oh yeah - you can go drop a blah-de-blah-de-blah in it and then you can finally put a lift kit on it and get it off road...

    ah welll....
  • My secret -

    Don't do anything to it. At all. Change the oil with synthetic when the change oil light comes one. Replace the battery when it won't hold a charge. Never, ever, change the plugs.

    Tires. Headlights. Brakelights.

    Drive it. Lots.

    Um, the plugs? Gotta change those no later than 100K. You're joking right? Or maybe you like not passing your smog check, getting crappy gas milage, worse performace and looking at your check engine light. I dunno.

    Forget about that lift kit stuff. Front axel runs right through the oil pan. I haven' been paying attention to this board lately, but I don't know as anyone's gotten around that.

    Ross, have you changed your plugs? I just ordered a half dozen from RockAutoDOTcom for $38. All 6 from Kragen's or Autozone would have cost me over $75. Rockauto Rocks! Anyways have you changed yours? Any advice before I tackle it. Also is you have a minute have you replaced shocks as well? I was wondering on the front struts once I unbolt the assembly if I can expect the spring to try and take my head off? Will the spring need to be compressed before disassembly?

  • I have a question about how much room there is in the Chevy Trailblazer that has the 3 rows of seats. I am traveling to NH and my sister is planning on picking us up at thBoston airport in her Trailblazer. She swears that she'll be able to hold all of us and our luggage, but she's not good at estimating things like this, so I'm hoping someone here can help me....

    We'll have to fit 4 adults, which includes my sister who's driving, two car seats to hold the two kids that are 3 years old, and then our luggage and one of those large strollers that fold down. I've read that the 3 seat Trailblazer holds 7, but will it also hold all the luggage and stroller, or does the third seat take up the room that luggage would fit in?

    If anyone can help me, I'd really appreciate it....Thank You!
  • fmportfmport Posts: 9
    Yes you should be ok. The third row seat is good for your kids with car seats, and you can fold down the single seat on second row, This would leave you with the space from the folded seat on second row, and the space behind the third seat for luggage.

    Anyone have trouble with the front differential leaking?

    My local shop diagnosed the leak as being from the front diff. They said they have seen many Envoys/Trailblazers with this problem. $261 to replace the seal. But they said it's really hard to fix.. have seen repeats.

    Any others?
  • seifordseiford Posts: 68
    I can find reference to a TSB titled "Repeat front axle leak", but can't find the whole bulletin. It's listed as TSB# 3177, (NHTSA # 10010599).

    Does anyone have the whole bulletin?
  • Has anybody seen this problem in their vehicle with the same climate control system as a Olds 03 Bravada? Let's say I'm standing idle for an extended amount of time, my outside temp on the climate control screen will start to click down to -33F which in turn effects the cabin temp and will stay while I'm driving.
  • Sounds like a temp sensor. Easy / cheap fix, do a search for more info..

    If i recall about $16 and ten minutes of time
  • is it leaking from the cv joint?

    I have a 2003 Envoy that continues to blow a fuse that shuts off the turn signals, the compass and thermometer reading. While driving down the road the tac continues to bounce, but the engine is not reving. The air won't work, the cruise won't work. The vehicle will run until you turn the key off. After that it won't start until the fuse is changed. The dealer had it for 3 weeks last fall, but could not find a problem. When it happens we just have to change the fuse. Seems to happen consistantly when it has sat in the sun, then you put the air on. Anyone have this problem or a similar one? :(
  • Thanks, I look into it.
  • bobed2121bobed2121 Posts: 70
    A shop had to re-charge our battery and now the climate (HVAC) controls do not work at all. Fuse? There is no display on the controls and hot air is even coming out of the front defrost vents. Blown fuse?

    Original BFG wearing out after 40K on 2004 LS, with some cracking. Drive 50% highway, 50% city. What would be a long lasting, fairly quiet tire? Seems to be a choice between knobby truck tires or more passenger car tires. Any advantages/disadvantages to either? Tire shop recommended General Grabber HTS. Thanks.
  • burdawgburdawg Posts: 1,524
    Knobby truck or off road crossover style tread will be noisier, especially on the highway.
    I would go with a regular highway style tread based on your use (all paved roads). Using a performance tire on a Trailblazer only buys you aesthetics, it's not a sports car by any means.
    I put Coopers on my 02 when it was time, a good value with above average ratings, and I've had no complaints.

    I'm at about 35K miles on my 5-1/2 year old Bravada (obviously light duty). Last fall, based on a check of transfer case fluid, my GM BadWrench shop said that the tech said that the fluid looked dark and should be changed; only about $350. Decided I hold off until this summer based on financial considerations. Today, Mr. BadWrench says that the tech said that the transmission fluid looked dark and should be changed. New low price of about $165. I mention the transfer case fluid issue from last fall and he says don't worry about that, because of the synthetics in the fluid it will go for 100K miles. I said no to the transmission fluid change at this time.

    Now the service requirement for the transfer case fluid is 50K miles and for the transmission fluid is 100K miles. I've read that there is some sensitivity regarding the transfer case fluid and it may be a good idea to change it early. But, this whole thing seems like a sales job for service I don't really need. The vehicle does not exhibit any symptoms of any problems with the transfer case or transmission.

    I have a 2003 Trailblazer that is doing the same thing. The dealer said they would have to run down every circuit and there were several on that one fuse.
  • jdavis12jdavis12 Posts: 19
    I have the exact same problem.....and don't live on the north pole. Please reply when you find the part number and whether replacing the temp sensor fixed the problem. Does anybody know where that sensor is located?
  • yatesdyatesd Posts: 60
    My Bravada came standard with the Michelin Cross Terrain tires. These are expensive, but well worth it. I replaced my first set at 75K miles only because I was heading into Winter and had two tires patched for holes. They last a long time, are quiet, and handle well. I am also please with the traction in the rain and the snow.

    BTW, is generally a great place to get tire reviews.
