Mercury Mystique 1995-2000 has two main fuse boxes: the passenger-compartment panel below the dashboard on the driver’s side and the power-distribution box in the engine compartment. The data covers 2.0 Zetec and 2.5 Duratec versions.
The most important production change came for 1999. Cars from 1995-1998 use the earlier under-hood box, while 1999-2000 models use a redesigned power-distribution box with additional high-current positions 39-52.
Fuse-box locations
Passenger compartment: below the dashboard on the driver’s side. Release the retaining lever to lower the panel.
Engine compartment: on the driver’s side. The box contains the main fuses and relays; its layout changed for 1999-2000.
