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.

heater/A/C unit won't work but turns on, cruise control lite

While driving the vehicle, the A/C stopped working on the medium setting. I tried the others(settings) and the A/C would only work on the high one. While on the high setting the cruise control lite on the dash would come on even if the cruise control was off. The next day I replaced the blower fan relay ($45) which didn't fix the problem. Same issues happened. The problem has now progressed, the A/C doesn't work at all, nor does the cruise control. Twice, since the start of this, EVERYTHING started to work normally only to malfunction again. Any ideas? The dealer wants to charge $120 an hour to fix the problem.
