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.

2004 Toyota Corolla Owner Comments

My vehicle's air conditioner (2004 Toyota Corolla) is not working properly. The system will work for a few moments (blowing out cold air) and then will start blowing warm to hot air. The fan still works, there is no loud noises and I can hear the compressor engage when I turn the system on. I have researched this problem on the internet and have found that many other people are having the exact same problem and that bringing this fact to your attention many result in a recall of the unit. I have also read that Toyota has added and extra plastic piece to the A/C condenser on 2007-2009 models. Thank you for reading this and for standing up for consumers.
