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.

Air conditioner blower speed decreases when brakes are applied and engine speed decreases. Air conditioner recirculate button spontaneously cuts off. Rear air conditioner blower speed drops when brakes are applied and engine speed decreases and then completely stops blowing despite rear A/C control remaining in the on position. Rear A/C button must be turned off, then turned back on to restart blower. Voltage meter shows a drop in voltage when brakes are applied and engine speed decreases.
