My Father has a 1987 Grand Marquis with A/C and a 5.0 Litre engine.
The problem I am having is the blower motor for the HAVC sytem works in every position but the floor mode I changed both the engine dash light and the engine coolant sensor for computer sensors but it still doesn't work.
Is their a relay either inside or or outside the vehicle that could be bad and if their is where would it be located at?

Sounds like the floor vent door is not opening. Can you still here the blower motor running when in floor mode?
