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.

While driving with A/C set on "auto" the A/C system would suddenly turn off by itself and would turn of repeatedly when started again. During such episodes the A/C would act erratic with fans turning on and off at different outlets, cycles between heating and cooling, and makes hissing sounds. This would occur many times a day on a daily basis in summer weather (except when the car is taken to the dealer, it seems). It took about 2 years for the dealer to finally fix the problem since they could not avoid admitting its existence after I had video taped the malfunction and showed them the video..
