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.

1998 Mercury Grand Marquis Owner Comments

problem #1

Feb 152008

Grand Marquis 4.6L

  • Automatic transmission
  • 161,557 miles


The fan for the defroster does not come on as long the temperature is below freezing. Even after the car has been warmed and running for for several hours, the fan is only on fast enough to defrost the window IF there is only one person in the vehicle. As the vehicle was a gift, I cannot ask the previous owners what gives, but I have experienced the problem prior to owning it. The intake was replace in late 2008 with no problems. (the rad fan had shorted out and had be re-wired so it works fine)
