tam nguyen: My 2005 trailblazer has blend door actuator problem front and back. Have to tear the dash apart to get to the actuator. The transmission failed at 56K. I bought the extended warranty for $2,500 so it cover the transmission.
foxstan: I have a 2005 Trailblazer also. There are problems that are a result of poor engineering but maybe that is why they quit making them. Overall satisfied. We had several gauges quit working. The gauges have plastic gears that strip. We sent the entire gauge cluster to a shop in Canada that replaced the plastic gears with brass and we have not had any more gauge problems. The front main seal failed on a trip to California and a dealer there replaced it. Engine light was set because the thermostat had failed open and the engine did not heat up in the prescribed time frame. Can't just buy a thermostat but must buy a hose assembly with the thermostat. Yesterday it failed to pass emissions and from my research may just be a blown fuse. Who in their right mind links a computer anything with a cigar lighter which has a heavy inductive load? Seems like it would cause a voltage drop and spike. Anyway, computers should be on their own circuits. Will probably follow Patrick Brown's advice for the next passenger vehicle. Chevy and Ford are lacking good engineering and quality in important areas and refuse to step up to the plate and fix them.
G. Steven Pirttila Jr.: now not only Speedo issue but entire gauge cluster...some times fuel gauge reads empty right after fill up, volt meter drops to 0 and back again...alarms sound, seatbelt light, airbag light, etc flash on and off...just started after 100,000 miles, once again 2005 Trailblazer...
sir jaime roland ruiz: WHO GIVES A freak! HOW DO YOU FIX IT?
SuperGmann10: You can replace the stepper motors in these for about $15 each. Available on ebay or amazon.
didier banegas: if you truck started to stall while driving, replace the fuel pump even if is still working, no throttle or fuel injection clean up will fix this issue. I have owned 3 Chevy trucks already and this is very normal in this trucks. v8 5.3L always have valve issues. L6 engine is better. every time you fix a electric or electronic issue reset the computer.
Adrian Wilson: Put n a cluster from an 02 Trailblazer. They don't come with them stepper motors. I bought one by accident To go in my 04 Trailblazer.
Ronaldo Panaligan: Another piece of crap electronic is the PCM in the 2005-08 Ford Escape. Around 100k miles the ECU decides it will drive the ignition coil with DC signal so it will overload and burn both the coil and computers power IGBT. Whoever programmed that piece of crap needs a boink on the head. They probably programmed it so it will do that lol. You can always insert a timer in any program. What a prik.
Ronaldo Panaligan: Modern cars have instrument cluster that communicate with the pcm through standard protocol in this case CAN. Imbedded system just like the car electronic system use micricontrollers, eeprom, roms register and all that crap. All it takes is a corrupt signal to mess up everything such as the as the transient voltage in an automotive environment. It boils down to poor circuit design
Jonathon LaFond: have a 04 and it has similar problems
john mclaughlin: I own a 05 chevy fail blazer by government motors gm I have every problem and then some that all of u are having its a crying shame how there hasn't been any recalls and hunny if u havnt had any problems I don't believe u no disrespect butt I don't that's like hitting the lottery I'm sry but that truck should have been recalled on so many levels urs truly john
trailblzer22: Same thing happened to my 2005 Trailblazer right after it went over 100,000 miles.
Айдар Ш.: чезахуйня
Alex's Bikes and Motors: the blazer was an awesome truck but the trailblazer was terrible.
Christopher E Simpson: I have a 2005 trailblazer. exact same issues. only item on cluster working is voltage gauge. already done thermostat when I had 30000 miles. doing water pump today. small things to do but aggrivating
MysteryWolph: Just about any car you buy is prone to some "common issue". When buying, research different vehicles that you might consider. Pick the one with the issues easiest for you to live with and/or fix.
G. Steven Pirttila Jr.: I have a 2005 Blazer with the same speedometer issue
