First off, you must ensure that it "IS" a short to ground. The first indication is that a fuse is blown, so check your fuse panel to determine if there are any fuses gone. Then, if a fuse is blown, then work backwards with a continuity tester to find the possible break in the insulation of the wire or the section of wire which is creating the short, then replace it Find the appropriate wiring diagram to help trace the wires as well.
A grand marquis wiring diagram can be found in a Chiltons or Haynes auto repair manual.

I want to find the book value of a 1992 grand marquis car Go to www.kbb.com
I couldn't find one in the fuse layout page of the manual that came with my 1987 Grand Marquis. I would assume not.

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!
