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.

In my 2004 GMC Sierra the wiring harness for the A/C down near the passenger floorboard smokes and I smell burning plastic and my A/C doesn't work and I talked to a few other GMC and Chevy owners and they have the same problem. So if alot of people are having the same problem I think its something to look into...
