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.

problem #1

May 092011

Grand Marquis ES 4.6L V6

  • Automatic transmission
  • 120,114 miles


The a/c will not blow cool air. The car has the automatic climate control module. It happened recently and we unhooked the hot wire from the battery. This served to reset the computer. After being unhooked for a few minutes, we re-connected the cable and the a/c worked just fine. This cure worked for about a month. We traveled over 4000 miles and had no problems. Yesterday it happened again. We dislocated the battery cable again and the reconnected it. This time resetting the computer didn't furnish us with a solution. Now that it is getting warm and we need a/c, the a/.c won't blow cool air.
