FUSES
WARNING!
- When replacing a blown fuse, always use an appropriate replacement fuse with the same amp rating as the original fuse.
- Never replace a fuse with another fuse of a higher amp rating.
- Never replace a blown fuse with metal wires or any other material.
- Do not place a fuse inside a circuit breaker cavity or vice versa.
- Failure to use proper fuses may result in serious personal injury, fire and/or property damage.
- Before replacing a fuse, make sure that the ignition is off and that all the other services are switched off and/or disengaged.
- If the replaced fuse blows again, contact an authorized dealer.
- If a general protection fuse for safety systems (air bag system, braking system), power unit systems (engine system, transmission system) or steering system blows, contact an authorized dealer.
- When a device does not work, you must check the fuse element inside the blade fuse for a break/melt.
- Also, please be aware that when using power outlets for extended periods with the engine off may result in vehicle battery discharge.
- Fuse Element
- Blade Fuse with a good/functional fuse element.
- Blade fuse with a NOT functional / BAD fuse element (blown fuse).
Fuse Location
- The fuses are grouped into a controller located in the engine compartment.
Underhood Fuses
- The Power Distribution Center is located in the engine compartment near the battery.
- This centre contains cartridge fuses, mini-fuses, micro-fuses, circuit breakers and relays.
- A label that identifies each component is printed on the inside of the cover.
- Before any procedure is done on the PDC, make sure the engine is turned off.
- Remove the cover by unlatching the two locks located at each side of the PDC cover, avoid the usage of screwdrivers or any other tool to remove the cover, since they may apply excessive force and result in a broken/damaged part.
- After service is done, secure the cover with its two locks.

FAQs
The 2018 Pacifica typically has two fuse boxes: one in the interior cabin, often under the dashboard, and another in the engine compartment. The exact location may vary depending on the trim level and model.
To access the interior fuse box, you may need to open the driver’s or passenger’s side door and remove the cover panel located beneath the dashboard. For the engine compartment fuse box, lift the hood and look for the fuse box near the battery or other designated location.
Fuses in the 2018 Chrysler Pacifica are designed to protect various electrical circuits and components from damage caused by electrical overloads or short circuits. They act as safety devices that interrupt the circuit when a fault occurs.
A blown fuse can often be identified by a broken or melted metal strip inside the fuse. You can visually inspect the fuses or use a multimeter to check for continuity if you’re uncertain.
Yes, most fuse replacements are straightforward and can be done by the owner. Refer to your owner’s manual for guidance on the location and type of fuse needed.
No, it’s not recommended to use a fuse with a higher amp rating as it can lead to electrical damage or even fire hazards. Always replace a blown fuse with one of the same amp rating specified in your owner’s manual.
