Why won't my 1992 grand marquis shift out of park?

APPLY BRAKES AND SEE IF BRAKE LIGHTS COME ON. IF NO BRAKE LIGHTS, REPLACE THE BRAKE LIGHT SWITCH LOCATED ON THE BRAKE PEDAL ARM AND THIS SHOULD ALLOW YOU TO SHIFT OUT OF PARK. IF THAT BRAKE LIGHT SWITCH IS BROKE, YOU WON'T BE ABLE TO GET IT OUT OF PARK
