#18111 of 18274 A couple of things...can any TB owner relate? by gmfan4 Jan 11, 2008 (7:17 pm)
I have 2006 LT TB with the 5.3 V-8, not the EXT. I bought the car back in Aug 2006 and everything has been great...I already have 43,000 mi on it. A couple of things:    1. When looking under the hood around the battery, there is an on/off switch...I have never seen this before and was wondering if others had this. My vehicle does have an aftermarket anti-theft device, but I never activate it...it came with the car...do you think it could be the aftermarket device? If so, I wonder if I could turn it off. I bought the car new and the dealership had already installed this on the vehicle.    2. Sometimes, if the vehicle has been sitting overnight or a couple of days, when I crank it up the clock reads 12:00 like the battery was disconnected. All of my pre-set radio channels works fine and are still in memory, but the clock must be rest. Anyone else have this happen? The battery appears strong and is putting out 13-14 volts    3. When I put the vehicle in park, sometimes (and this is going to sound crazy), the speedometer jumps from 0-40 mph and immediately back down...it only does this once when it happens, and it occurs about twice a month.    4. Sometimes when I enter the vehicle, the CD charger is making noise like it thinks there is a CD, when I do not have one in. What the heck? I don't even have the key in the ignition and the CD is "shifting" like it is looking for a CD or trying to eject something.    Thanks for any help. Much appreciated!
#18112 of 18274 Water pump replacement job - 2002 TB by johntr Jan 28, 2008 (2:07 pm)
I started hearing a rattling type noise from the engine at idle speed. I figure it is most likely the water pump bearings. I don't have any leaks, but I want to replace it as soon as possible. My question to those that may have taken the task on them self... Is this something that I could do rather than taking it to the garage. I have ~128K miles on it. It's a 2002 Trailblazer, I-6 engine. If it is something I can do, what should I expect to run into? (remove fan, fan clutch, serpentine belt, ect...?) I am fairly mechanical, I used to do my own repairs from valve cover gasket replacement, manifold gaskets, engine starter replacement. But I have never worked on anything newer than 1990.   Just trying to get some ideas as to the value of the job.   Thanks John Replies to this message: ugltrk (Jan 29, 2008 1:29 pm) johntr (Feb 02, 2008 1:20 pm) johntr (Feb 17, 2008 11:01 am)

Replying to: johntr (Jan 28, 2008 2:07 pm) John, I would check the idler/tension pulley bearing before I went too far.I've had them rattle, and squeal like a water pump.   gmfan4,..I would suspect the radio..   Just a shadetree guess...Bill Replies to this message: johntr (Feb 02, 2008 1:20 pm) johntr (Feb 17, 2008 11:01 am)

Replying to: ugltrk (Jan 29, 2008 1:29 pm) 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.   John Replies to this message: johntr (Feb 17, 2008 11:01 am)

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

Replying to: johntr (Feb 02, 2008 1:20 pm) 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.
#18117 of 18274 Wet left foot? by seiford Feb 18, 2008 (10:18 am)
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?   Thanks.
#18118 of 18274 02 TB LTZ 4X4 switch by bobed2121 Feb 19, 2008 (9:09 am)
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?
#18119 of 18274 '02 Red Trailblazer - RIP by wharthog69 Feb 19, 2008 (8:10 pm)
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?

Replying to: wharthog69 (Feb 19, 2008 8:10 pm) 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! Replies to this message: wharthog69 (Feb 20, 2008 4:45 pm) ross1962 (Feb 22, 2008 2:48 pm) bobed2121 (Mar 06, 2008 8:50 am)
