I have a 93 and my switch is behind the passenger side kick panel.
I have a 1995 Aerostar and the switch is on the passenger side, inside the door, down below the dash, behind the moulding. Hopes that this helps.
The inertia switch is just above the carpet on the passenger side in front of the door opening, it will have one plug with two wires and a red reset button on top.
On a 1997 Ford Aerostar : The fuel pump shut off switch ( inertia switch ) is in the front passenger footwell , behind the kick panel * the kick panel is the interior trim panel , just in front of the front door , by the persons feet
It is located inside the cab behind the trim in front of the passengers door.
under the passenger carpet
Bad relay? Blown fuse? Bad ground?
I believe it's on the passenger sidewall under the dash near the door.
