1999 Mercury Grand Marquis Service and Repair Manual

Known issues on the 1999 Grand Marquis. Five recalls are on the federal record. Replacement steering shafts fitted to this car can separate while it is moving, which is a loss of steering control. Aftermarket fuel filters whose quick connectors feel attached but never fully seat can let gasoline out near an ignition source. The jacking instructions can direct the jack onto a frame weld that may yield and drop the car on whoever is under it. Two more cover service belt assemblies that may not restrain an occupant. Owners have logged 203 complaints — 29 on the engine and cooling system, 20 on steering, 17 on the suspension.
