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.

On 6/27/2013 I was driving home, I remember opening my windows using the main buttons on the drivers door. On the morning of 6/28/2013 the windows stopped working, since i don't have working airconditioning this is a safety concern. I have an appt to bring it into my mechanic, who is an incredible mechanic. It appears to be a circuit breaker, however the owners manual tells you it is a circuit breaker, it does not tell you where this is located. It will now cost me money I really don't to repair this problem.
