* Underhood Fuse Box: Located in the engine compartment, usually near the battery. This box contains higher-amperage fuses protecting major electrical components.
* Passenger Compartment Fuse Panel: This is typically found under the dashboard, on the driver's side (in some models, it might be on the passenger side). This box contains lower-amperage fuses for interior lights, accessories, and other smaller circuits.
To be absolutely certain of the location and to identify which fuse controls what, consult your 1997 Ford Aerostar owner's manual. The manual will have diagrams showing the location of both fuse boxes and a legend indicating what each fuse protects. Without the manual, identifying the correct fuse can be difficult and potentially dangerous.
