Quick Answer
The 2020 Jeep Gladiator features three primary fuse box locations: one under the hood, one in the passenger cabin (behind the passenger kick panel), and one in the rear cargo area.
Under-Hood Fuse Box (Power Distribution Center - PDC)
The Power Distribution Center (PDC) is located under the hood, on the passenger side of the engine compartment. It contains high-current fuses and relays for critical vehicle systems such as the engine control module (ECM), fuel pump, ignition, starter, headlights, and ABS. Always verify the specific fuse layout against the diagram on your PDC lid, as variations can occur based on trim level and optional equipment.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| F01 | 20A | Yellow | Powertrain Control Module (PCM)/Engine Control Module (ECM) |
| F03 | 20A | Yellow | Fuel Pump |
| F05 | 20A | Yellow | Ignition Coils |
| F06 | 40A | Green | Blower Motor |
| F08 | 30A | Green | ABS Pump Motor |
| F10 | 10A | Red | A/C Clutch |
| F12 | 10A | Red | Headlamp (Low Beam - Left) |
| F13 | 10A | Red | Headlamp (Low Beam - Right) |
| F14 | 15A | Blue | Headlamp (High Beam - Left) |
| F15 | 15A | Blue | Headlamp (High Beam - Right) |
| F18 | 20A | Yellow | Trailer Tow Connector (Trailer Brake) |
| F20 | 10A | Red | Starter Solenoid |
| F22 | 25A | Clear | ABS Valves |
| F30 | 10A | Red | Powertrain Control Module (PCM) Ignition |
Relay Locations (Under-Hood PDC):
The PDC also houses several relays. Common relays include:
- R8: Starter Relay
- R10: Fuel Pump Relay
- R14: A/C Clutch Relay
- R15: Blower Motor Relay
- R16: Low Beam Headlamp Relay
- R17: High Beam Headlamp Relay
Passenger Cabin Fuse Box
The passenger cabin fuse box is located behind the passenger kick panel, near the passenger's right footwell. You may need to remove a trim panel to access it. This fuse box typically controls interior accessories, the radio, power outlets, and other cabin-related systems.
| Fuse # | Amp | Color | Circuit / Component Protected |
|---|---|---|---|
| F60 | 20A | Yellow | Radio/Infotainment System |
| F62 | 20A | Yellow | Power Outlet (Cigar Lighter/12V) |
| F65 | 10A | Red | Brake Lights |
| F67 | 15A | Blue | Tail Lights / Parking Lights |
| F68 | 5A | Tan | Airbag Control Module |
| F70 | 10A | Red | Instrument Cluster |
| F72 | 15A | Blue | Power Windows |
| F75 | 7.5A | Brown | Heated Seats (if equipped) |
| F77 | 10A | Red | Interior Lights |
| F80 | 20A | Yellow | Wiper Motor |
| F82 | 10A | Red | HVAC Control Module |
Rear Cargo Area Fuse Box
The 2020 Jeep Gladiator also has a fuse box located in the rear cargo area. This fuse box typically manages power for accessories in the bed, trailer connections, or other rear-mounted electrical components. Its exact location can vary, but it
Before you pull a fuse on the 2020 Jeep Gladiator
- Use the label printed on the panel cover or the owner's manual for your exact build. Layouts change with options, model year and build date, so a chart for another truck can be wrong.
- Replace a blown fuse only with the same amp rating. A larger fuse can let wiring overheat.
- A fuse that blows again right away means a short or failing component downstream. Find the cause before replacing it again.
- A good fuse doesn't prove the circuit works — relays, grounds and connectors fail too.
- Disconnect the battery before working near high-current fuses or cables.
