In this article, you will find information about the fuses of the Ram 1500 (models 2019, 2020, 2021, 2022, 2023, and 2024), including diagrams of the fuse boxes, a list of fuses, their designation, and the location of the fuse blocks within the vehicle.
Checking and Replacing Fuses in Ram 1500
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.
Caution!
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.
Location of Fuse Boxes
Internal Power Distribution Center: The Power Distribution Center is located under the driver’s side instrument panel. This center contains cartridge fuses, micro fuses, relays, and circuit breakers.
Locate and remove the two screws from the lower portion of the fuse panel cover.
After removing the screws, gently pull both the left and right side of the fuse panel cover to release the fastener clips.
Reverse the procedure to reinstall the fuse panel cover.
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.
