2025 RAM 1500 Fuses and Fuse Box Owner’s Manual
Fuses and fuse box protect the vehicle’s electrical system from overloading and short circuits in 2025 RAM 1500. Fuses protect electrical components by cutting the circuit if current flow exceeds acceptable levels.

FUSES Guide
General Information
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. 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. 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.
CAUTION!
If it is necessary to wash the engine compartment, take care not to directly hit the fuse box, and the windshield wiper motors with water.
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 using power outlets for extended periods of time with the engine off 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)
Underhood Power Distribution Center
The Power Distribution Center is located in the engine compartment near the battery. This center contains cartridge fuses, micro fuses, relays, and circuit breakers. A description of each fuse and component may be stamped on the inside cover, otherwise the cavity number of each fuse is stamped on the inside cover that corresponds to the following chart.
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.

Auxiliary Switches
Four or six auxiliary switches may be located in the lower switch bank of the instrument panel, and can be used to power various electrical devices.
The functionality of the auxiliary switches can be changed via the Uconnect Settings. All switches can be configured for setting the switch type operation to latching or momentary, power source of either battery or ignition, and ability to hold last state across key cycles.
NOTE
Holding last state conditions are met when switch type is set to “latching” and power source is set to “ignition” within Uconnect Settings.
The auxiliary switches manage the relays that power four or six blunt cut wires. These wires are located under the hood to the right, near the battery.
In addition to the four or six auxiliary switch wires, a fused battery wire and ignition wire are also found in this location.
A kit of splices and heat shrink tubing are provided with the auxiliary switches to aid in the connection/installation of your electrical devices.
Fuse And Wire Color Chart
NOTE:
Fuses for the auxiliary switches can be found in the auxiliary Power Distribution Center (PDC), located in the engine compartment toward the front of the vehicle, in front of the main PDC. Remove upper shield to access. If equipped, additional auxiliary switch fuses will be located in the main PDC.

FAQ’s
The main fuse box in the 2025 RAM 1500 is typically located under the hood on the driver’s side, near the battery.
To access the fuse box, open the hood and locate the fuse box cover. Inside the cabin, remove the panel or cover to access the interior fuse box.
Fuses protect the electrical circuits in the vehicle from overloads and short circuits by breaking the circuit if the current exceeds a safe level.
A blown fuse will have a broken metal strip inside or appear discolored. You can also use a fuse tester to check for continuity.
Replace the blown fuse with a new one of the same amperage rating. Ensure the issue that caused the fuse to blow is addressed to prevent it from happening again.
You typically need a fuse puller or a pair of needle-nose pliers to safely remove and replace fuses.
Many vehicles come with spare fuses located in the fuse box, but it’s advisable to keep an assortment of spare fuses on hand for emergencies.
