2020 Jeep Gladiator Fuses
The fuses in a vehicle’s electrical system are like quiet sentinels that protect against electrical surges and overloads. They are part of the vehicle’s complex electrical system. Several processes in the Gladiator depend on these seemingly unimportant parts to work well and last a long time. The electrical currents are controlled by the fuses, which are in two fuse boxes. One is in the engine room, and the other is in the cabin, out of sight. When there is too much electricity, a fuse’s “sacrificial” system kicks in, breaking the circuit and stopping any damage that could have happened. This safety feature protects important parts of the vehicle, like the lighting systems and vital components, and makes sure that power is spread evenly throughout the Gladiator. Even though they are small, these fuses are essential to keeping the Gladiator running and giving drivers the peace of mind that they will have a safe and efficient driving experience.
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 higher amp rating. Never replace a blown fuse with metal wires or any other material. 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, gearbox system) or steering system blows, contact an authorized dealer.
GENERAL INFORMATION
The fuses protect electrical systems against excessive electrical 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 an extended periods of time with the engine off it may result in vehicle battery discharge.
- Fuse Element
- Blade Fuse with a good/functional fuse element
- Blade fuse with a bad/not functional fuse element (blown fuse)
POWER DISTRIBUTION CENTER (PDC)
The Power Distribution Center is located in the engine compartment near the battery. This center contains cartridge fuses, mini fuses, and relays. The PDC top cover is labeled with each serviceable fuse/relay location, function, and size.
NOTE: Fuses for safety systems (marked with *) must be serviced by an authorized dealer.

CAUTION
- When installing the power distribution center 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 center 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.
FAQ
Fuses are electrical safety devices designed to protect various components in the vehicle by breaking the circuit in case of an electrical overload.
The 2020 Jeep Gladiator typically has two fuse boxes: one in the engine compartment and one in the interior cabin.
The fuse box in the engine compartment is usually located near the battery and contains fuses for various engine-related components.
The interior fuse box is often located on the driver’s side of the dashboard or near the lower part of the steering column.
The Gladiator may use blade-type fuses, which are flat, rectangular fuses with a variety of current ratings.
A blown fuse can often be identified by a broken or melted metal strip within the fuse, visible through a transparent window on the fuse.
The fuse ratings indicate the maximum amount of current the fuse can handle before breaking the circuit. Higher ratings mean the fuse can handle more current.
Yes, replacing a blown fuse is typically a straightforward process. Refer to the owner’s manual for fuse locations and ratings.
Most fuse boxes can be accessed with simple hand tools like a fuse puller or needle-nose pliers.
No, it’s important to always replace a blown fuse with one of the same rating. Using a higher-rated fuse could lead to electrical damage or fires.
If a fuse keeps blowing, it indicates an underlying electrical issue. Consult a professional mechanic to diagnose and fix the problem.
Some vehicles include spare fuses in the fuse box or a fuse kit. Check the owner’s manual to see if your Gladiator has spare fuses.
It’s generally a good practice to disconnect the negative terminal of the battery before working with fuses to prevent electrical hazards.
Yes, the fuse box includes fuses for various accessories and components, often labeled for easy identification.
Fuse box diagrams are often included in the owner’s manual. You can also find them online or through the official Jeep website.
