Fuses are located either in the engine compartment or passenger compartment fuse and relay panels. If a fuse blows, a single component or single circuit will not function properly. Excessive current draw is what causes a fuse to blow. Observing the condition of the fuse will provide insight as to what caused this to occur.
A fuse with signs of burns, melting of the plastic shell, or little to no trace of the wire that once served as the conductor indicates that a direct short to ground exists.
- Remove the fuse or relay box cover.
- Inspect the fuses to determine which is faulty.
See Figure 1
- Unplug and discard the fuse.
- Inspect the box terminals and clean if corroded. If any terminals are damaged, replace the terminals.
- Plug in a new fuse of the same amperage rating.
- Check for proper operation of the affected component or circuit.
