Hope this help to solve it (remember comment and rated this).

From the 1997 Mercury Grand Marquis 4.6L SFI 8cyl repair manual, the Flasher is located behind left side of instrument panel. The turn signal and emergency flashers are attached to the interior fuse panel. They are replaced in the same manner as the fuses and circuit breakers.

ther is a plastic guard with 3 locking caps that need to be turned clockwise a quarter turn to remove. remove from the front. you will then have be able to see and have access to the lights and adjustment screws

Pop the hood, there is a tray that sits over the radiator, if the locks are still intact, twist them until the tray comes free, (There should be 3 plastic locks) remove the tray. Now you have access to the lights. There is an orange plug on both sides (L&R Headlights). Turn the plug until it frees up, then slide plug out of headlamp fixture. Then simply pull the bulb out and replace with new bulb.

here is a diagram for you. 1994 grand marquis

unscrew the headlight bezzle (there are four or six screws) pull the bulb casing out, twist out the old bulb and insert the new one.

I changed the front left marker light on side of headlight assembly by unscrewing the screw on the far back of it. then i just pulled it off. it felt like it was gonna break but it came off just fine

You didn't mention your rear brake lights. If they don't work either then you probably have a bad light control module (LCM). This is a common problem with big Fords. You can buy a replacement part ($250) or have yours rebuilt (www.autoecu.com). The module is located under the dash to the right of the steering column and is fairly easy to replace.
Do the turn signals work? If not it may be the turn signal switch. The aftermarket parts are cheaper than a Ford factory part; check the guarantee before deciding.
Worse case scenario? You need both parts.
