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.

GM would not stand by the part. It probably actually gradually failed from the getgo. This part, when it fails, makes the A/C system inoperable at low speeds. Makes you think you lost your charge, when that is not the problem. It is only a $30 part, but I did the work myself. It just sucks that GM does not admit that it is a design flaw in the original part. My Silverado had the same problem at 30k and GM would not stand behind that on either!

I have talked to many other car owners and they have their own stories about their vehicles.... I still like GM. I just lower my expectations of car dealers and brands in general. The system is there to bleed you of cash....and employ people that can't think for themselves or back you up...
