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.

I AM IN AFGHANISTAN AND GET TO LISTEN TO THE WIFE COMPLAIN ABOUT THIS SITUATION. SHE HAS BEEN TO THE DEALER TWO TIMES AND THEY FIND NOTHING...THE PROBLEM DOES NOT APPEAR. AFTER A COUPLE DAYS THAN THE PROBLEM STARTS UP.

WHEN USING THE AIR CONDITIONING SOMETIMES THE NUMBER 1 COOL/ FAN SETTING DOES NOT WORK. IF PLACE IN NUMBER 2 SETTING IT WORKS, THEN ALL OF SUDDEN YOU GET HOT AIR OUT OF BOTH DRIVER AND PASSENGER VENTS. SOMETIMES YOU GET HOT AIR FROM DRIVER VENTS AND COOL AIR FROM PASSENGER VENTS.

same problem as reported above. Dealer cannot give me an accurate quote. I have a background in auto repair, but it has been quite a few years ago. Can this be done at home by myself.
