WinchesterLock: Yeah, I too have an 05' Trailblazer. My cluster has been going to heck for
months (only issues regarding the fuel gauge are covered by recall btw).
Just this weekend, I had the oil pressure, amperage and speedometer all
fail on me. Oil and amperage were normal when checked/hooked up to an
outside meter. The speedometer decided to move off of zero after driving
an hour and a half with no speedometer. This comes following having
repairs done for a bad coil, a recall replacement for a fuel gauge issue, a
dead battery, and rough idling and choking down at stoplight when I have
the air conditioner or fan on (the dealership claimed it was a dirty
throttle body, and having them clean it did nothing to fix it). As a
result, I have no interest in buying another Chevy.
FanOfVacuums2: We have a black 2005 Blazer that had the same problem. It would say we were
going 120mph, when we were going like 30. The gas gauge didn't work either,
we just estimated how much gas we had. All we did was replace the little
stepper motors and it worked like new. The check engine light constantly
stays on, but we don't pay attention to that. It works almost like new,
earle butler: YES CHECK ENGINE LITE SIT OVER NIGHT CHECK ENGINE LITE ON .
Darlene Hickman: I also have a 2005 and just got it so i was not paying for repairs on my
car and i have the same problems gauges and pump and now when i put on the
breaks it sometimes jumps forward this is a great vehicle for winter but
other then that it is killing me in repairs and now my door lock to driver
side is locking on me would not recommend to anyone unless u have money to
pay out !!
Cathi Singledecker: ThIs was a recall item only covered until 100k miles. My mechanic sent mine
in this must be done on the cluster that came with truck cost 70bucks.
Everything working fine now.. hope this helps everyone! !!
Kevin Stephanie: I have all these issues too and not sure what to do about it.... I am so
sick of everything falling apart on this vehicle... please help with any
MusiikN0w: our 06 envoy has been nothing but good so far, only have replaced the 4wd
switch and had to put tires on it, bought at 96k miles now has 105k cluster
works great and its driven daily
Alfonso Barrera: i have a 05 trailblazer and it is acting crazy also...i ran out out gas the
other day because my fuel gauge went out...and now my truck feels like it
wants to turn off...i think my speed sensor its out now...
JC Ayala: hope u didnt replace it looks like a simple speedometer gauge stepper motor
prob. $20 fix
josh pellett: replaced both motors for the needles both fixed for under 50. bucks did it
jeff hamilton: You really need to have the front suspension and wheel bearings checked.
Wheel bearings usually go bad about every 50,000 as well as ball joints and
a-arm bushings. This may be the worst vehicles GM has produced sense the
old 5.7 diesels.
Shelley Luster: We have one. The cluster is broken. We recently took it in for a recall on
the gas system. Not too happy with it. Also the steering keeps going out.
Patrick Bryant: Also have a 2005 trailblazer i keep filling the radiator, but i think the
water is coming out from the water pump im not sure.
Ramiro Rodriguez: Theses trucks are nothin but junk. I replaced the water pump, the clutch
fan, the wheel bearing all 4, the calipers, the upper and bottom plate ,
ball joint, the cluster is going krazy, all in less the an year. Need less
to say, I hate american car, I got me a toyota camry.
Mindy Skewes: I also have an 05, with the same issues. Speedometer works randomly. Engine
light stays on, fan does not work on 5. Today the oil pressure gauge went
to 0. I wish they would recall the whole cluster.
Kimi Banderas: Yes i do have the same year and same problem stuck at 120 and goes down to
90 in park grrrrr
Mitchell WildFlame: Oh I've done 90 mph with our 04 in park! ._. no, it was slipping on ice
and the gear shift was in drive, but it displayed on the dash as park for
Aman P: i got chevy trailblazer 05 i am facing exact same problem i went to chevy
dealer they dont cover any of that. & now just today i put in drive it
dont run. seems like its not shifting at all. if you kno what could be that
please let me kno.
Patrick Whitt: I have a 2oo5 trailblazer. when it had 40,000 mi I had to replace the idle
pulley that was a defect. change the water pump at 60,000 that is standard.
I had to change the crank sensor, cam sensor, both 02 sensors at the same
time because i had a bad power surge and loss of power and check engine
light. at 96,000 I had to replace the fan clutch because loss of power and
it started running warm"very expensive" most recently at 100,000 I had to
replace the shift cable, a common problem. it breaks at the transmission
and either you can put in a bushing or pay $80.00 for the whole new cable.
From my knowledge trailblazers have bad electrical problems but are a very
Dean Kiley: Gauge cluster is easily repairable for about 35 bux by replacing the
stepper motors (6 in all). Instructions are found on youtube, parts
available on ebay. This is an EASY fix and if you can hold a pencil, you
can solder. I will be replacing the original cluster lamps with blue led's
as well as soon as it gets a bit warmer. Good Luck!
robin mericle: I have a 2004 Chevy Trail Blazer. The fan belt clutch was replaced at the
dealer Blasius Chevrolet in 2008. I then moved to FLA. where I had to have
the FAN BELT clutch Replaced again in 2011, again REPLACED in 2012. Now its
going on a 4th time.
Steven Baessler: I have an 03 trailblazer lt 5.3 vortec, my gauge cluster got stuck
also, what I did was act like I was going to start my truck with the
shifter in drive. some how if you do this enough ( on mine at least ) the
speedometer will slowly bring itself back to just under zero. the reason
for leaving the truck in drive is so the truck don't keep starting. so,
leave it in drive, try to start it and hold the key a second, all gauges
should fall to the standard off position, when you release the key, gauges
will go back into whatever they are supposed to read and on top of that
your speedo should start to slowly move back to normal " 0 " mph position.
this may take several attempts but like I said, its what works on mine.
flydivafly: I also have the check engine light, (that doesn't bother me) speedometer,
and fan for the heater problems..Do you know of any recalls? I have had a
new fan put in twice and neither time does it get any better..The
speedometer as u say is about $300 to get fixed.
Michael Shahabi: I own a 2004 Chevy Trailblazer LS 4.2 I6, It has given me problems galore!
I have replaced the fuel injector, thermostat, and my gauge is having the
same problem since 2009. The only gauge that works is the RPM, my gas light
goes off thats howI know I need gas, I will never buy GM again! I currently
have a misfiring cylinder #4, and other engine lag. Just ordered a new fuel
Kyle Howell: Those trucks ain't worth nothing.
Alfonso Barrera: my truck also runs out of oil really fast...they told me that the fuel
regulator might be broke...i dont understand since these are two different
josh pellett: yes i got the same problem or did but mostly with the tac
Erik Carlson: (Virtual fist bump)
Erik Carlson: Hi Vanessa. Thanks so much for sharing your story. We're in the same
boat...we don't trust our fuel gauge so we fill up often and watch our
mileage. I'd hate for my wife and children to be stranded alongside the
road with an empty tank due to a faulty fuel gauge. :(
slb5150: LOL....I own one of these lemons, too....gas tank level sensor, bad cluster
gauge, water pump, wipers that won't turn off....I feel for ya, buddy. I
stick my wife with this thing....I'll keep driving my Neon.
XMANDEEJAY: I had the same problem.Had to replace the whole dashboard .
Teresa Rodriguez: I've had my 05 Trailblazer for 71/2 years and absolutely love it. It has
been a very good vehicle for me. I have put over 165,000 miles on it, and
it still runs very good. Sure, I have had to put a little work into it, but
I would have expected that on any vehicle. Recently, the AC stopped blowing
cold air only on the drivers side. I took it to the dealer and my advisor
told me what it was (in the dash), but I don't remember the name that he
said. Does anyone know what the name would be?
Erik Carlson: That stinks. Hopefully it's something minor. Thanks for the comment!
shonuffgrl: Same problem with my speedometer.
68simplejay: My wife owns a 05 blazer and the same thing happend to it the speed will
stick and I also just replaced the water pump waiting for the next disaster
to happen with this truck
ramonaahakeem86: I have had my 03 Trailblazer for 1 year. I've had many problems with it.
Now my transmission is going bad. Wanna cry but as soon as I'm done
something else will be wrong with it.
Erik Carlson: Bummer. Sorry to hear that Scott. Hope you don't have any other issues with
your Trailblazer. Thanks for posting!
arrow251: Needs to be resynchronized by authorized service center. Check engine light
needs to have fault code checked. My thermostat went bad and caused the
check engine light to come on, the thermostat was stuck open and did not
allow the engine to reach correct temperature in allotted time. Fuel gauge
started giving bad reading that was caused by faulty fuel level sensor in
gas tank, GM paid for most of that one though issue.
Vanessa W: I have a chevy trailblazer - 2005 and my fuel gauge is shot. I will get it
fixed one day, but for now I fill up based on my mileage. :) Not the
smartest thing, but its better than forking out 400$ for it... Guess I
should prepare for future repairs as well.
Erik Carlson: I totally feel for you Ramona. Hopefully you won't have any more issues
with your vehicle. Good luck!
Erik Carlson: Thanks for your sharing your story @jrled79. I hope you don't have any more
problems with your Trailblazer. We used our GPS for a while too. After we
got the cluster fixed, our speedometer is about 4 - 5 mph slower. I
wondered why everyone is passing us. heh.
jrled79: I have an 2005 Trailblazer. My speedometer went out at about 100,000 miles.
I had the vehicle speed senor on the transmission changed and nothing
happened. Will have to change the cluster. For now I use my Motorola GPS's
speed indicator to track my speed. It's like 2 to 3mph off. Now I am having
trouble with my fan clutch. It's slow turning cause my A/C to cycle
irregularly. If it ain't one thing, it's another.
James Gillespie: i feel for you, havent had those problems yet. but at 100,400 miles the
transmission went out, dont replace it with same tranny. i put an escalade
tranny in mine. not long after that the rear end and water pump went out.
my advice, if you havent replaced tranny yet dump this vehicle as soon as
jumpin386: I bought a used 05 trailblazer that the speedometer did not work. I bought
the servos for the dash cluster on ebay for around 40.00. They work well
for the speed , the gas gauge sometimes reads low when it is full but
everything else works fine.
Josh Corpuz: Dcv
Kendra Sanders: I have a 2005 EXT LS and am being nickle and dimed like you said. I've
replaced the entire exhaust all rotors, 2 of the ignition pins and still
have my check engine light, this has all been changed in the last 3 months.
Erik Carlson: Hi Rocco - I'm no trailblazer expert but if you read through the comments
below, your check engine light could mean a number of things...from serious
to not-so-serious issues. It's probably worth having it checked out. Good
luck to you!
Erik Carlson: Ah...that stinks. We got our speedometer fixed but it actually runs about
4-5 mph slower than the speedometer. Go figure. Hope you don't have any
other issues with your Trailblazer. Bless you!
Erik Carlson: Je n'ai aucune idée de ce que vous venez de dire parce que je ne parle pas
espagnol, donc j'ai pensé que je voudrais vous répondre en français.
Erik Carlson: Hi Marta. I'd do what everyone else does...watch your mileage and fill up
often. It would stink to be stranded alongside of the road with an empty
