To find the correct fuse, you must consult your owner's manual. The manual will have a fuse diagram showing the location of all fuses and what each one controls.
If you don't have the owner's manual, you can try:
* Online resources: Search for "1997 Ford E-350 fuse box diagram" online. Many websites offer downloadable diagrams. Be sure the diagram matches your specific van's year and options.
* Ford dealership: A Ford dealership can provide you with a diagram or help identify the correct fuse.
Important Note: Before checking any fuses, always turn off the ignition. Incorrectly handling fuses can lead to electrical damage or injury.
