I also have a 2003 Trailblazer that the speedometer is malfunctioning at random times. The needle will reed incorect speeds on some trips and work fine on the next. A dealer quoted us $400 - $600 to replace the speedometer to see if that would fix the problem. This is rediculious that they have recalled the speedometers on the sister vehicles with the same issue but refuse to take care of this issue. I have been a long time GM customer but I am now considering replacing my Chevy with a foreign fullsize (they seem to stand behind their product better). Mike |

| I put the 4wheel drive to the AWD position,it switched over to AWD but then the lights started flickering on the dash and the 4wheel drive kept engaging and disengaging even though the tires were not spinning. I put the truck in 4Hi and all trouble went away. The next day my wife put the truck in AWD and the service 4wheel drive light came on, she parked the car at a store and when she went to leave she started the truck and it would not come out park,the dash lights wouldn't work, the blower didn't work,only the radio and headlights would come on(and we had troulbe getting the key to turn off). I put the 4wheel drive switch back into 2Hi and it would not switch over, I tried the same with 4Hi with no luck. After about 1hr of starting the truck and turning it off, diconnecting the battery and pulling many fuses the truck finally went back to 2Hi and all the trouble went away. I've been experimenting putting the truck through all the 4wheel drive modes and everything thing seem to be alright, then yesterday when I put it in AWD the dash lights went out again and the AWD system was engaging and disengaging(pulsating)even though I was on dry pavement. I tried to put it back in 2Hi and it wouldn't switch over, then I put it in 4hi and it switched over and everthing worked fine again. When I switch from 2Hi to 4Hi I don't have any trouble it's only in the AWD mode. No codes are stored on the computer. Any help would be grateful. | |

Hello, first of all anything would help. I purchased a 2005 Chevy Trailblazer from a "reputable" used vehicle dealership. It has been one problem after another in the 21 days that I've had this vehicle. Most recently was after I had the tranny flushed and the front and rear diff done. While driving home if I have my foot on the accelerator all is well, however if I take my foot off the gas pedal at a minimum of 30 miles an hour my headlights dim as well as my dash lights and almost completely go out. Dim (almost completely off) then come back on when I step on the gas pedal again. My battery registers that it's at 14 (right in the middle). What's the deal? Any help would be great since I've already put over $800 into this new "used" POS.

I bought an 06 Trailblazer and had my one year anniversary Dec 6th of 2008. It has been a NIGHTMARE since I bought it and the dealership won't buy it back. I was hoping there were similar issues that someone could suggest that I have them look at at the dealership, they are ready to total it so they don't have to look at it anymore, I didn't think that was a good solution. Here are a few of the issues: -Sounds and feels like driving on rumble strips at 45-70mph LOUDLY. -Tranny intermitant shifting problems -Mild intermitant vibration at 35-70 mph in gas pedal -Diminished Eng Capacity Light comes on and off - Intermitant 12mph max speed -Speed/Power cuts out randomly (no more acceleration regardless of gas pedal pressure) -Trac light intermitantly on -Check engine light intermitatly on -Clock auto resets itself occasionally -CD randomly pops out on startup or shut down or while driving -Vehicle shakes and chugs worse than a disel pickup on start up occasionally -Cruise control sometimes quits on its own -Replaced transmission pump/ignition switch -Torque converter locking up (tech told me potential problem) -Starter sometimes has issues, turn key and nothing...no click, hard turnover, nothing then wait 10-15 seconds and without touching the ignition switch the truck starts. -Continually warping rotors -Clunk on occasion when shifting from "P" to "R" or "R" to "D" -After startup while idling sometimes there is a loud clunk from the passenger side sounds like someone is kicking the side of the truck -Windows intermitantly work powering up -Transmission "whistles" when rpm's going up to shift occasionally -Radio/CD sometimes just shuts off That's about all I can think of off the top of my head I have had it in the shop at least 50 times in the past year and they keep telling me their computer doesn't say anything.....last week it lit up like the 4th of July but they still couldn't figure out why all the problems. If anyone can help with ideas that would be great, I don't know what else to do. It is all still under warrenty thank goodness!!! They now found coroded wires, replaced the starter, replaced throttle body, new stereo is on order, replaced the weather stripping, two speakers, and the vibrations, whistling, revving and other shimmying is still an issue. I did some digging and found out that my vehicle HAD been in an accident (the dealership told me it had never been) only 27 days before I bought it in 06! It hit a deer at 60mph, could this be part of the problems with it???? Does anyone know if I can pull up all the parts ordered for my vehicle by the vin?
