Changing a Fuse

Fuses

WARNING:  Always replace a fuse with one that has the specified amperage rating. Using a fuse with a higher amperage rating can cause severe wire damage and could start a fire.

If electrical components in the vehicle are not working, a fuse may have blown. Blown fuses are identified by a broken wire within the fuse. Check the appropriate fuses before replacing any electrical components.Fuse Types

Callout	Fuse Type
A	Micro 2
B	Micro 3
C	Maxi
D	Mini
