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.

2004 Chevy Impala--both turn signals and hazard lights stop flashing. Tried to replace fuses, but all still good. Could not locate a turn signal relay in the fuse box. Spoke to a mechanic who said it didn't make since that there was no relay in the fuse panel. Looked up the turn signal switch part and it was on back order. The part alone was over $300. Mechanic also stated it did not make since that it would be the turn signal switch when all other components on the turn signal arm (windshield wipers, cruise control, etc.) still worked. Unable to go to the dealership since it was a Sunday. Looked up other similar complaints on and found several people having the same problem. Was advised to turn on and off the hazard several times. In doing so (about 100 times) the signals started working. Therefore, it doesn't seem as if this is a turn signal switch issue, but a hazard switch issue. This is a very dangerous situation if driving and your turn signals stop working which could cause a serious accident.
