I took my blazer in because my instrument cluster failed, they replaced it, and we noticed around 1500rpm it would make a noise I can only say sounds like a cow mooing. We complained, and left our TB with them for over a week, and they say they tried 6 different instrument clusters and all of them made the same sound. I find it hard to believe that all GM remanufactured insturment clusters make the same sounds. The sounds is driving me nuts, any answers?

Some told me about thermostat but gauge shows normal

I asked a friend who works on vehicals everyday and he said it was the EGR valve, but the model I have dose not have a EGR valve, what could be the cause, I do have a check engine light on. This only happens at Highway speed, when the trailblazer has made it's final shift, and we are cruzing. Just want to know a little before I get the run around at the shop!

i need change the valve cover gasket, already loso all bolt below but nothing is coming off do i missing something

all gauges are irradicate

OK HAD A DEALER REPLACE THE ECM ON MY TB A LITTLE OVER A YEAR AGO SAID IT WAS JUST OUT OF WARRANTY AND SO ON. SO ABOUT A MONTH LATER STARTED THROWING CODES IN AND OUT OF SHOP SEVERAL TIMES WITH NO FIXS ABOUT TWO WEEKS AGO IN THE FIRST COLD SPELL CAR SHUT OFF AND WOULD NOT RESTART AFTER TROWING PARTS AT IT ON SEVERAL CODES WAS RUNNING FINE UNTILL TEMP DROPED BELOW FREEZING AGAIN. NOW THROWING A P0601 CODE INT CONTROL MODULE MEMORY CHECK SUM ERROR? AFTER RESEARCH EVERYTHING POINTS TO REPLACEING THE PCM. IS IT AND THE ECM THE SAME THING AND DOES IT NEED TO BE PROGRAMED AFTER BEING REPLACED IM BEING TOLD THAT I CAN GET A ECM AT AUTOZONE AND THEY CAN PROGRAM WITH MY VIN # TO THE SPECS. IT NEEDS TO BE BUT I THOUGHT A PCM AND A ECM WAS TO DIFFERANT MODULES?

ONLY DOES IT WHEN COLD LIKE BELOW FREEZING AFTER IT DIES TURN THE KEY AND THERE IS NOTHING. CHECK ENGINE LIGT IS ON POWER DOWN LIGHT AND TRACTION CONTROL LIGHTS ARE ALL ON WHEN IT WILL NOT START. BATTERY GOOD NEW ALTNATOR CLEANED THROTTLE BODY. I RECENTLY CHANGED MY WHEEL HUB ASSY. THATS WHEN THE TROUBLE STARTED. BEFORE I CLEANED THROTTLE BODY CHECK ENGINE LIGHT WAS ON AND THROWING CODES P0014, P0506, P1400 AND WAS IDELING RUFF AND STALLING CLEANED THROTTLE BODY AND RAN THE BEST IT EVER HAD THEN TEMPS DROPED IT STARTED THIS AND ITS NOT LIKE ITS LOSSING POWER AND DYING IT JUST SHUTS OF I WAIT A FEW SEC. WITH THE KEY REMOVED THEN REINSERT IT WILL START AND MAY RUN FOR A MIN THEN SAME THING. ANY LEADS ON WHAT TO CHECK WOUL BE APPRICIATED.

can i do it myself, does it have to be programed or is a junk yard one ok

The check engine light is on and then it blinks and runs bad then it goes on solid after a few seconds and runs fine again

I cannot pass inspection due to a cracked neck on my gas tank. The check engine light was reset to off. I was told to drive the car another 100 miles and to bring it back in. The check engine light was off, but I failed inspection again. The car has 95,000 miles on it and I want to sell it versus putting out $1000 to replace the tank.
Any recommendation is appreciated. Is their anything that I can add to the gas tank which would seal the leak and allow me to pass inspection?

CHECK ENGINE LIGHT COMES ON AND STAYS ON.

CHECK ENGINE LIGHT IS ON AND YOU CAN HERE TH FAN BLOWING REAL HARD

I was told from a chevy dealer that I need a new motor(7000)instead of replacing the camshaft autuator. I wanted to know how much is an autuator and is it expensive to replace?

Is my trans a 4L60E??

needs spark plugs but cant find them, what are they under?

car runs rough and idles roughly

when driving. I stop the engine and restarte the car the light will go off and stay for 3 to 4 days. I have no codes.

I hate this vehicle...the mileage sucks for one, the fuel pump failed before the warranty expired, no help had to pay like $588.00 for a new one and labor, now the evap system for the fuel injectors are out another $600.00 bucks. The lights dim when you use the windows, the center console has no support, the seats are falling apart, wind noise is unbelievable, and speakers are all out of wack sounds like the speakers are under my car. I'm tired of all the headache with this particular vehicle I will never buy another chevrolet vehicle...I feel they have just become sloppy are careless with their vehicles. I'm not recommending their vehicles to family, friends, or enemies...

I just picked up my Trailblazer from having it's transmission rebuilt. The service engine light was still on when I got there. The "assistant" checked for codes and got PO756. He reset the computer, told me to go ahead and drive it, and see if the light comes back on again as he is only the assistant. They are closed over the weekend and call Monday to talk to the tech that did the rebuild as there was no breakdown in actual parts on the bill. My tranny was slipping BAD and had lost reverse and it seems to be shifting fine but the shop is only 5 miles away and I haven't drivin it any further than that. I need to know how "easy" of a fix it is and a time frame to do it just in case. I've already been without my vehicle for the last 5 days! :( You would think they would have checked it and replaced it and reset the computer before finishing the job. This shop has good reviews. That's why I took it there. Thank You!!

battery is good weve changed ignition fuses under hood but windows wont roll up security light on radio will come on please help me
