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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2000 Chevrolet Blazer Owner Comments

problem #4

Apr 022009

Blazer LX 4.3L V6

  • Automatic transmission
  • 62,074 miles


Didn't check coolant level of freezing in -30C weather, truck overheated in winter, probably freeing up the heater core and putting tiny hole in it. Truck smelled like anti-freeze whenever heat was turned on. A definite clue, with no cure but to replace the heater core! I think GM must have hanged the heater core from a wire on the assembly line, the built the truck from there out!!

I've had my Blazer for 3 years now and have been fairly happy. This summer, my windows started fogging up. It's worse in the winter! I try to defrost my windows and it gets foggier and smells like fish! Foggy vapor comes out of the vents. I drive with my windows cracked and the vents covered just to see. I have a four year old and one on the way. I can't wait to get a new car. I'm looking into Nissan.

Blazer LS V6

They told me that replacing the coolant and backflushing it got the heater core to work again. But if it stopped again, they have to replace it.
