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 have had 7 mechanics look at this issue and no one can fix it!!!!

I have Raynaud's and cold weather makes it so I can barely move my hands and can be in danger of loosing my fingers.

Sub-zero temps in Buffalo today. :-( The heater works as long as the car is moving. When stopped or idling the heater blows cold air! Had it checked last winter, they told me they could not find a leak, said it probably was leaking into the engine, would cost $2000.00 to fix a broken gasket. Temperature gauge works fine, car is not overheating. I add about a cup of anti-freeze every 2 weeks. Please help!
