To find the correct fuse:
1. Consult your owner's manual: This is the best place to start. The manual will have a diagram of the fuse box and list what each fuse protects.
2. Check the fuse box: Locate the fuse box in your 2000 Dodge Neon (usually under the dash on the driver's side). Look for the fuse labeled as related to the power outlet, lighter, accessory, or something similar. The amperage rating will be printed on the fuse itself (often 10A, 15A, or 20A).
3. If you can't find it: If you can't locate the correct fuse using the manual or the fuse box labels, try testing each fuse with a multimeter (if you have one) to see which circuit corresponds to the power outlet. Be careful not to damage anything while doing this.
Do not attempt to replace the fuse with a higher amperage fuse. Using a higher amperage fuse than specified is dangerous and could lead to a fire. If a fuse blows repeatedly, there's an underlying electrical problem that needs to be addressed by a qualified mechanic.
