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.

2003 GMC Sierra 1500 A/C works when not turned on but when you hit the A/C button the A/C stops working. I have talked to several people and no one seems to know what would cause it. A/C is fully charged and blows out at 58*F, can't use max A/C because the compressor stops when the A/C is turned on. It has the electronic dual climate control in it.
