2019 Chevrolet Malibu Fuse Box Diagram & Amperage

Quick Answer

The 2019 Chevrolet Malibu features three main fuse box locations: under the hood, inside the cabin (driver's side kick panel), and in the rear cargo area (trunk).

Under-Hood Fuse Box

The under-hood fuse box is located on the driver's side of the engine compartment, near the battery. It houses fuses and relays for critical engine components, powertrain, and some chassis systems. Always consult the diagram on the fuse box lid for the most accurate information for your specific trim level.

Relay Locations (Under-Hood):

• RL1: Cooling Fan Relay 1
• RL2: Cooling Fan Relay 2
• RL3: Starter Relay
• RL4: Fuel Pump Relay
• RL5: A/C Clutch Relay
• RL6: Horn Relay
• RL7: Headlight Low Beam Relay
• RL8: Headlight High Beam Relay

Cabin Fuse Box (Driver's Side Kick Panel)

The cabin fuse box is located on the driver's side, behind a trim panel in the kick panel area. This fuse box primarily handles interior electrical components, infotainment, power accessories, and safety systems.

Rear Cargo Area Fuse Box (Trunk)

The rear cargo area fuse box is typically located on the driver's side of the trunk, behind a removable access panel. This fuse box generally controls rear-specific electrical components, such as tail lights, fuel door release, and some convenience features.

How to Test a Fuse

Testing a fuse is a straightforward process. You will need a fuse puller (usually found in one of the fuse boxes) and a multimeter or a fuse tester. Always ensure the ignition is off before removing or inserting fuses.

1. Locate the suspected fuse: Refer to the fuse box diagrams above and your vehicle's owner's manual to identify the fuse for the circuit you are troubleshooting.
2. Visually inspect: Many fuses have a visible wire element inside. If this wire is broken or melted, the fuse is blown. However, not all blown fuses are visually obvious, especially the smaller or mini fuses.
3. Use a fuse tester: A simple fuse tester lights up if the fuse is good. Touch the probes to the small metal test points on the top of the fuse. If it lights up, the fuse is good. If not, it's blown.
4. Use a multimeter: Set your multimeter to the continuity setting (often indicated by a speaker icon). Touch the probes to the metal test points on top of the fuse. A good fuse will show continuity (the multimeter will beep or display a closed circuit). A blown fuse will show an open circuit.
5. Replace with the correct rating: If a fuse is found to be blown, replace it with a new fuse of the exact same amperage rating (e.g., replace a 15A fuse with another 15A fuse). Using a fuse with a higher rating can lead to serious electrical damage or fire.

Common Blown Fuses on This Vehicle

While any fuse can blow under the right circumstances, some circuits are prone to blowing more often due to usage or potential issues. On the 2019 Chevrolet Malibu, common culprits include:

• Cigar Lighter/12V Outlets (Cabin Fuse Box, F8 - 20A): These fuses frequently blow due to overcurrent from charging multiple devices or using high-power accessories. If your phone charger or other accessories aren't working, check this fuse first.
• Blower Motor (Under-Hood Fuse Box, F5 - 40A): Issues with the blower motor or resistor can cause this high-amperage fuse to blow, leading to no cabin fan operation. If your HVAC fan isn't working, this is a prime suspect.
• Radio/Infotainment System (Cabin Fuse Box, F1 - 20A): Electrical glitches or aftermarket installations can sometimes cause this fuse to pop, resulting in a dead radio or infotainment screen.
• Headlights (Under-Hood Fuse Box, F11/F12 - 20A, F13/F14 - 10A): While less common, a short in the headlight circuit or a failing bulb can sometimes cause these fuses to blow, resulting in one or both headlights being out.

Always remember to check the simplest solutions first. If a fuse blows repeatedly, it indicates a deeper electrical issue that needs professional diagnosis.
