To find the correct fuse:
1. Consult your owner's manual: This is the best resource. It will have a diagram of the fuse box showing the function of each fuse.
2. Check the fuse box diagrams: There are often diagrams printed inside the fuse box cover itself, or you might find online diagrams specific to the 1998 Jeep Cherokee (searching for "1998 Jeep Cherokee fuse box diagram" will yield results).
3. Use a multimeter (optional but recommended): If you're comfortable with basic electrical testing, you can use a multimeter to test the continuity of each fuse to find the blown one. Caution: Always disconnect the negative battery terminal before working on the electrical system.
Since there's variation, don't rely solely on forum posts or general information. Use your owner's manual as the primary source, then follow steps 2 and 3 if needed.
