2020 Jeep Gladiator Fuses and Fuse Box | How to fix a blown fuse
Fuse boxes control and protect electrical components in the 2020 Jeep Gladiator. Some fuse boxes are positioned under the dashboard or in the engine compartment for easy access. Fuses prevent electrical overloads and protect sensitive components. Fuse break or “blow” when current surpasses a threshold, breaking the circuit and averting electrical problems.
Refer to the 2020 Jeep Gladiator owner’s manual for instructions and the fuse box location. You can also find fuses, their amperage ratings, and the electrical systems they safeguard in the manual. For the vehicle’s electrical system and features to work, fuses must be checked and replaced regularly. Use caution and follow safety standards when working with vehicle electrical systems and fuses. If you need help with fuse replacements or electrical concerns, see a mechanic or the dealership.

FUSES
- 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 period 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.

- 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.
FAQs
The fuse box for the 2020 Jeep Gladiator is placed beneath the hood, near the battery.
Locate a black box with a removable lid by opening the hood. Fuse diagrams are usually on the lid.
Check the “HEADLAMP” fuse in the fuse box. If it blows, replace it with a same-amperage fuse.
Power windows are often regulated by a fuse designated “PW” or “PWIND” in the fuse box.
Check for a fuse with a broken filament or visible melting. This diagram on the fuse box lid can assist
Only replace fuses with the same amp rating. A fuse with a greater or lower amp rating may cause electrical harm.
If a fuse repeatedly blowing, it may indicate an electrical issue. Check the vehicle’s handbook or hire an expert to diagnose and fix it.
Spare fuses are typically found in fuse boxes or available at vehicle parts stores. Get the right amp rating.
The radio is usually controlled by a fuse labeled “RADIO” or “AUDIO” in the fuse box.
Use only the proper fuse type and amp rating from the vehicle’s manual. Using the wrong type can cause electrical issues
Some fuse boxes have clear plastic covers. Fuse testers or multimeters can be used instead.
Removing a fuse while driving can cause electrical issues or damage components. Before changing fuses, switch off the engine.
The air conditioning system may have a dedicated fuse. The fuse box diagram shows where to find the fuse.
Fuse replacement with circuit breaker is not advised. Use your vehicle’s recommended fuses.
