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.
Thomas S: OOOOH Yeah... this 2005 TrailBlazer is killing us. Cluster is always giving
us grief... if we go more than 30 miles the speedometer will drop down pass
the 0 mark and on some occasions while driving, it will climb to the 100mph
+ mark but our speed is normal.Check engine light is always on, gas mileage
is TERRIBLE Lucky to get 12 hwy. and the list goes on on and on. NEVER buy
2005 TrailBlazer LS
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
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
JC Ayala: hope u didnt replace it looks like a simple speedometer gauge stepper motor
prob. $20 fix
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.
josh pellett: yes i got the same problem or did but mostly with the tac
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.
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,
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.
earle butler: YES CHECK ENGINE LITE SIT OVER NIGHT CHECK ENGINE LITE ON .
Marcus Bradshaw: I have engine light on and sunroof broke
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! !!
Kimi Banderas: Yes i do have the same year and same problem stuck at 120 and goes down to
90 in park grrrrr
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.
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
Washington Multimedia: my 03 trailblazer cluster has also gone bad, water pump, fan clutch,
transmission linkage gone bad also
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...
josh pellett: replaced both motors for the needles both fixed for under 50. bucks did it
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.
Darin Hill: I too have an '05 trailblazer. Speedometer quit working last summer '13,
been Rollin with the GPS ever since. It needs about $1000-$1500 worth of
work. Replaced ball joints, master brake cylinder. Hatch glass is rustd
shut some how. Haven't used it in about 3 years. Thought this was an
upgrade from my
Glenn Bosworth: Hey Erik, No you are not the only one with trailblazer issues. I own a 2004
with huge electrical issues that noone has been able to pinpoint as most of
the time it does not repeat at the service center or they think they got it
and a week later well you know. I bought it for 18K and have spent another
20K+ in trying to fix it. I go through headlights every 3 -4 weeks. My kids
call the dashboard a disco ball. I have replaced every interior light at
least 10 times. Most recently I had the instrument cluster redone with
LED's in an effort to not replace the bulbs as often. Some days it starts
then other it just sits there. It tells me that I am an unknowm driver from
time to time, usually while driving. You name it and it does it. If I could
afford it this would have been gone long ago. Now I just enjoy the flashing
lights and the guages occasionally going around like the second hand on a
clock. I will be posting a video I took a month ago. I have always favored
GM products and service. That is dwindling of course. Good luck to you. By
the way don't replace the cluster, send it out to have the servos motor
replaced. It is way cheeper. I keep 2 spare clusters in my garage as
backups now. Both of which I bought and would not let the deaership keep
the parts. Now my rebuilt original is back in.
jmbbtiger: I have a 2005 chevy silverdo with the exact same speedometer issue. It
started this at around 85K miles. I haven't considered having it looked at
/ repaired due to $$$$,, and hearing you say it might cost upwards of $300
is a bummer. Thx for the post.
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.
Tim Carlson: ERIK if you start your car and shut if off start and shut it off
mulitiable times it will go back to o
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
b1ballar: Cleaning the throttle body will clear the engine code for the cost of
throttle body cleaner. 5 dollars tops. Cluster is some bad luck but a lot
of these problems you could fix yourself for a lot lot lot cheaper than a
shop. The rear differential on mine was leaking and I just pulled the cover
ran a new gasket and replaced the fluid and good as new. It sucks your
getting nickel and dimed but look on you tube for videos on how to repair
yourself you can save a lot of money... thousands
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 !!
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.
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.
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.
scgarcia74: I also have a 2005 Trailblazer and I keep having problems with the ignition
Cathi Singledecker: My trailblazer just started to act up yes the gas cap has problems but now
my speedometer is stuck and my blower fan just went out two days ago it
would not turn off... nite I have no heat and it's 19 degrees. ...uhhhh
blondy4550: Yes I too have a 04' trailblazer and my cluster panel has went out and so
did my fuel pump and my mother board ad to be replaced then too have had
lots of issues in the ladt yr and I also take good care of my vehicle . It
looks new inside and out but is still coming apart! Now my four wheel drive
is not working! Anyon have any suggestions as to what is wrong? Sometimes

taylor lay: I have 20044 wheel drive switch has n light coming on any ideas on the
Mike Goss: Gettin ready to hit 100,000 on our 07 trailblazer,been a good truck no
issues so far but kept up all maintenance also
president carter jr: Cluster is bad
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.
