look under the air filter intake behind driver headlight to see if something is unplugged or on top of your air bags or check the switch in your trunk that controls air leveling
On a 1998 Mercury Grand Marquis : In the fuse panel under the dash : ( # 16 is a 20 amp fuse for the cigarette lighter and emergency flasher relay )
In a 1998 Mercury Grand Marquis ( fuse # 16 is a 20 amp fuse for the cigarette lighter and emergency flasher relay ) in the fuse box below and to the left of the steering wheel , by the brake pedal ( it has a cover on it )
Replace the flasher relay if none of them are working.
There isn't one. The 1995 Grand Marquis uses a lighting control prossessor. They are very expensive to replace. The part cost me $325.00.
On the left side of the steering column there is a light black tab that you pull down.
Fuse # 16 is a 20 amp fuse for the cigarette lighter and emergency flasher relay
there is a fuse panel under the instrument panel on the drivers side pull on both sides to remove it and the flasher is in there it is a large round peice on the top right
Flasher functions are part of the lighting module, there is no separate flasher.
It has 2 flasher relays. One for the turn signals and one for the hazard lights. The turn signal flasher is located on the drivers side, under the dash, driver side of steering column, mounted in the fuse panel.
Internal to multi-function switch. Multi-function switch is mounted with two bolts. This will be a 5 minute repair.
check the recalls there is something in there about tail light and signals
I have a 1996 Grand Marquis. If one of the brake lights goes out the signal on that side flashes faster. I would check the brake/tail lamps.
