2024 RAM 1500 Fuses and Fuse Box | How to change fuse
The 2024 RAM 1500 has an important electrical safety feature called the fuse system, which is meant to keep different electrical systems inside the car safe. The fuse box, which is a central spot for these safety devices, is placed in the car so that it is easy to get to. There are several fuses in the fuse box, and each one protects a different electrical line. As a safety measure, fuses break the circuit when there is an electrical overload or a short circuit. This keeps more important parts from getting damaged. To change a fuse in a 2024 RAM 1500, find the fuse box. This can usually be done inside the cabin or in the engine area. Check the owner’s guidebook or the cover of the fuse box for a diagram that shows where the fuses are located and what they do. Once you know which fuse is broken, use the fuse puller tool (which is usually in the fuse box) to remove it safely and put in a new one with the same power. A simple but necessary maintenance job is to check the fuses often and replace them as needed. This keeps the vehicle’s electrical systems safe and working well. Always follow safety rules, and look at the owner’s manual for the 2024 RAM 1500 fuse system for specific directions.

FUSES
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 a 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 with the engine off may result in vehicle battery discharge.
Blade Fuses
- 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 — If Equipped
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 the latch-ing or momentary, power source of either battery or ignition and the ability to hold the last state across key cycles.
Auxiliary Switch Location
NOTE:
Holding last state conditions are met when the switch type is set to “latching” and the 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 is 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, and in front of the main PDC. Remove the upper shield to access. If equipped, additional auxiliary switch fuses will be located in the main PDC.

FAQs
The fuse box in the 2024 RAM 1500 is typically located in the engine compartment, near the battery.
The 2024 RAM 1500 typically has two fuse boxes – one in the engine compartment and another inside the cabin.
You’ll need a set of pliers or a fuse puller, and replacement fuses of the appropriate amperage.
Check for a melted or broken metal strip inside the fuse. A visual inspection can often reveal a blown fuse.
The 2024 RAM 1500 typically uses standard blade-type fuses.
The fuse box covers a diagram that indicates the amperage rating for each fuse.
No, it’s crucial to replace fuses with ones of the same amperage to avoid electrical issues or damage.
Turn off the ignition, locate the fuse, use a fuse puller or pliers to remove the blown fuse, and insert the new one. Always follow safety precautions.
Some models may include a fuse kit with spare fuses. Check the owner’s manual for details.
Issues like a malfunctioning accessory, non-functioning lights, or other electrical problems may indicate a blown fuse.
Yes, a single-blown fuse can affect multiple electrical components, so it’s important to check all relevant fuses.
Some safety features might be connected to fuses, so it’s essential to check the owner’s manual for specific details.
Tripped fuses can usually be reset by simply replacing them with new ones of the same amperage.
Ensure the vehicle is turned off, and follow safety guidelines to prevent electrical shocks or accidents.
If replacing the fuse doesn’t solve the problem, it’s advisable to consult a professional mechanic to diagnose and address the underlying electrical issue.
