* Under the hood: This is the main fuse box and contains larger fuses and relays. It's usually located near the battery, on the driver's side fender well.
* Inside the vehicle: This is a smaller fuse box, often called the "power distribution center" or "interior fuse panel," and contains smaller fuses for interior components. It's typically located under the dashboard, on the driver's side. You may need to remove a small access panel or trim piece to reach it.
To be absolutely certain, consult your 1999 Jeep Wrangler's owner's manual. The manual will have diagrams showing the exact location of both fuse boxes and will list which fuse controls which circuit.
