Changing a Fuse

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 your 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.

WARNING: Always disconnect the battery before servicing high current fuses.
WARNING: To reduce risk of electrical shock, always replace the cover to the power distribution box before reconnecting the battery or refilling fluid reservoirs.

The power distribution box is in the engine compartment. It has high-current fuses that protect your vehicle's main electrical systems from overloads.
If you disconnect and reconnect the battery, you will need to reset some features. 

Passenger Compartment Fuse Panel

 

The fuse box is located behind the passenger airbag cover. You can
access it through the glove box.
Use the provided fuse puller tool to remove a fuse. It is on the fuse panel cover.

Inline Fuses

Your vehicle may have several inline fuses located in, or on, the battery cables located in the battery box (depending on application).
• All vehicles equipped with an Allison transmission have a 10 amp fuse located in the clean power cables located in the battery box.
• All vehicles have a 30 amp fuse located in the clean power cables located in the battery box.
• All vehicles equipped with hydraulic brakes have a 40 amp fuse located in the clean power cables located in the battery box. In addition, another 30 amp fuse is located in a fuse holder just above the power distribution center located in the vehicle’s engine compartment.
