Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

THAT'S MESSED UP THAT THESE GM DEALERS DON'T WANT TO HELP WITH THESE PROBLEMS, EVEN THOUGH I THINK THEY KNEW ABOUT THE PROBLEMS. IF IT'S NOT DEATH INVOLVED THEN IT'S LIKE F*CK YOU THEN. THAT'S NOT RIGHT. THEY NEED TO FIX THESE PROBLEMS. I HAD TO REPLACE A MOTOR, WINDOW REGULATOR, BLOWER, RESISTOR, WATER PUMP. DAMN WHAT'S NEXT.

Grand Prix GT 3.2L V6

  • Automatic transmission
  • 88,000 miles

Bought this car about 4 yrs ago and have had to replace the blower for the heater twice and warranty wouldn't cover either time. It is now working intermittently again. I am not fixing this problem again, The worst part of it not working is when it snows a lot here and I have to try to break the ice on my windshield. It just seems silly to me to have to replace a car because the warming ability of it can't be relied on.

The only 3 other problems with this car which was the water pump needing to be replaced, transmission fluid leak, and coolant leak. I'm not good with cars and I can't afford to keep dealing with this problem. Sad really, I had for 7 yrs. a 2005 Sunfire before I had this car and I never had any problems with it. That's why I thought Pontiac made good cars, guess not.

This is the third time in three years (i have only owned the car for almost 4 years now) that the blower motor went out. This time I was under the one year part warranty but over the mileage. The dealership that repaired it both times prior will not do anything for me. So I started a search to see if this is a common issue with my car type before I file a BBC on the dealership that fixed it. Has anyone had this issue?

On top of having this repaired at $600.00, now 6 months later the control module for the heater/AC needs to be replaced at another $280.00. What is next? This car is nickel and dime-ing me to death. I am going to junk this car and NEVER drive another Grand Prix again.

I HAVE A 2004 GTP. I'VE HAD ABOUT 2 YEARS. THE FAN ALWAYS SEEMED VERY WEAK. THE ONLY VENT THAT HAD REAL FORCE WAS THE CENTER VENT. NOT SURE IF THATS NORMAL. RECENTLY THE FAN STOPPED MOVING AIR COMPLETELY. A FEW DAYS LATER IT WORKED AGAIN, THE NEXT DAY I SMELLED A BURNT ELECTRIC SMELL COMING FROM THE VENT, THEN IT STOPPED A LITTLE LATER. IT HAS COME ON A FEW TIMES SINCE THEN BUT VERY BRIEFLY. A MECHANIC LOOKED AT IT AND SAID THAT IT WAS THE BLOWER MOTOR CONTROL MODULE AND WOULD COST $300 TO FIX. I WANT TO FIX IT MYSELF.

IS WHAT HE SAID CORRECT THAT ITS THE MODULE? WHERE IS THAT LOCATED AND WHAT DOES IT LOOK LIKE? WHERE CAN I GET THE PART?

The blower motor (a/c) shorted out. The mechanic informed us that it was a good thing the fuse blew or the car would have caught on fire. My finance was leaving work when this happened and thankfully not driving down the highway. I find it extremely hard to believe that a 2004 car is already having a/c problems, of course the warranty expired 10,000 miles ago. What a crock of sh*t!
