headlight relay location on a 2004 mercury grand marquis
how to remove right turn signal relay on 1986 mercury grand marquis
The relay for a 99 Grand Marquis heater is located on the kick panel on the driver's side of the car. The relay is located under the kick panel cover.
The 1999 Mercury Grand Marquis air suspension relay switch can be found on the firewall in the engine compartment. The air suspension relay switch will be on the passenger side of the firewall.
I was looking at the 1996 Mercury Grand Marquis Owner Guide and it shows that you can change each of the ( 4 light bulbs for the 2 low beam and the 2 high beam headlights ) ( the low beam headlights take bulb # 9006 ) ( the high beam headlights take bulb # 9005 )
If Its an older Grand Marquis its easy. Find the knob that you pull out to turn on the headlights. Now, just turn it clockwise and the light will turn off!
You have many relays in that vehicle, most are in the fuse and relay box under the hood.
Fuse or relay defective.

the black box on the left side of the trunk
If your headlights work, but your tail lights don't, your bulbs could be blown. It is possible that you have a shortage in your car.
Replace the flasher relay if none of them are working.
