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.

General Information
- The fuses protect electrical systems against excessive current.
- 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).
Underhood Fuses
- The Front Power Distribution Center is located in the engine compartment.
- This module contains fuses and relays.
- Fuse cavity location and descriptions are printed on the inside of the power distribution centre cover.
CAUTION!
- When installing the power distribution centre cover, it is important to ensure the cover is properly positioned and fully latched.
- Failure to do so may allow water to get into the power distribution centre and possibly result in an electrical system failure.
- When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating.
- The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload.
- If a properly rated fuse continues to blow, it indicates a problem in the circuit that must be corrected.

FAQs
The fuse box in the 2018 Chrysler 300 serves as a protective mechanism for the vehicle’s electrical systems. It contains fuses that break or blow when there’s an electrical fault, preventing damage to components and wiring.
The fuse box is typically located either in the engine compartment or inside the passenger compartment, often beneath the dashboard. The exact location may vary depending on the specific model and configuration of your Chrysler 300.
The 2018 Chrysler 300 may use various types of fuses, including blade fuses or cartridge fuses, depending on the specific model and trim level. Blade fuses are more common and are easily recognizable due to their flat, blade-like shape.
Refer to the owner’s manual that comes with your 2018 Chrysler 300. It typically includes a fuse box diagram that provides information on the location and function of each fuse. Match the fuse to the corresponding electrical component or system you’re troubleshooting.
If a fuse blows, it’s important to replace it with a fuse of the same amperage rating. The amperage rating is usually labeled on the fuse itself or can be found in the owner’s manual. Using the correct amperage fuse is crucial to avoid electrical problems or damage.
Yes, replacing a blown fuse is generally a straightforward DIY task. However, always follow safety precautions. Ensure the vehicle’s ignition is off, and disconnect the battery if necessary. Use the appropriate tools and handle fuses with care to prevent injury or damage.
Common electrical problems such as non-functioning lights, power windows, radio, or other accessories not working may be due to blown fuses. Checking the fuses is a good initial step in diagnosing these issues.
No, it is not recommended to use a higher amperage fuse as a replacement. Fuses are rated for a specific amperage to protect the electrical circuit. Using a higher amperage fuse can lead to electrical damage or even fires in extreme cases.
There’s no specific maintenance schedule for checking fuses. However, if you encounter electrical problems in your vehicle, it’s a good practice to start by inspecting the fuses as part of the troubleshooting process.
Replacement fuses can be purchased at auto parts stores or online. Ensure you get fuses with the same amperage rating as the ones you’re replacing.
