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.

the fan stopped working. I get heat, get this, when I drive a certain speed. If I listen real close, I can hear something like fan trying to turn. I can hear the fan clutch engage. Air conditioner won't come at all. I thought it was a fuse or something. tried replacing that. no difference
