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.

(reported on)

Envoy SLE 4.2L L6

  • Automatic transmission
  • 44,000 miles

The Speed 5 on the blower in the front A/C stopr working after like 42000 miles. I took the vehicle to Chevrolet and they told me that I have to replace to motor and the resistor wich it was at least 200 on parts plus labor, since I lived in Yuma, Az and during hte summer it is really crucial to have an A/C that works properly, it is really annoying not having that 5th speed working on the motor. I might just wait until it burns completely before i have to replace it.
