Ive had this happen one time & near the drivers side wheel well in the trunk behind the grey trunk liner there was a wire cut & it was releasing the trunk when put in reverse,so I repaired wire with a automotive but connector & it fixed it .
According to the 2002 Mercury Grand Marquis Owner Guide : The ON / OFF rocker switch for the rear air suspension is located : ( in the trunk , on the drivers side of the trunk , the Owner Guide shows that there is a label next to the switch )
Do you mean the fuel pump reset switch behind the trunk liner ( access hole ) ?
