2015 Chevrolet Malibu Fuse Box Diagram & Amperage

Quick answer

The 2015 Chevrolet Malibu has three main fuse box locations:

• Underhood Fuse Block: Located in the engine compartment, on the driver's side, near the battery.
• Instrument Panel Fuse Block: Located on the driver's side, behind a trim panel, below the instrument panel.
• Rear Compartment Fuse Block: Located in the trunk, on the driver's side, behind a trim panel.

Underhood Fuse Block

The underhood fuse block contains fuses and relays for various engine and front-end electrical components. Always verify the fuse legend on the fuse box cover, as configurations can vary slightly by trim level.

Relay Locations (Underhood):

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

Instrument Panel Fuse Block

This fuse block is located inside the vehicle, typically on the driver's side, behind a removable trim panel near the kick panel. It protects many of the interior electrical components.

Rear Compartment Fuse Block

Located in the trunk on the driver's side, behind a trim panel, this fuse box handles power distribution for rear accessories and some body control functions. Ensure you consult the vehicle's owner's manual or the fuse box lid diagram for precise fuse identification, especially if your vehicle has specific optional features.

Relays (Rear Compartment):

• RL1: Rear Defogger Relay
• RL2: Trailer Brake Relay (if equipped)

How to Test a Fuse

1. Safety First: Turn off the ignition and any electrical components. Disconnect the negative terminal of the battery for added safety, especially when working in the underhood fuse box.
2. Locate the Fuse: Refer to the appropriate fuse box diagram (underhood, instrument panel, or rear compartment) to find the fuse you need to test.
3. Visual Inspection: Pull the fuse straight out using a fuse puller (usually found in the fuse box lid or with the vehicle's tools). Hold it up to the light. If the metal wire or strip inside the fuse is broken or discolored, the fuse is blown and needs replacement.
4. Multimeter Test (for less obvious breaks): If the visual inspection is inconclusive, use a multimeter set to continuity mode (often indicated by an audible beep or a horseshoe-shaped symbol). Touch one probe to each metal blade of the fuse. A good fuse will show continuity (a beep or a reading close to zero ohms). A blown fuse will show no continuity or an "OL" (open loop) reading.
5. Replace Cautiously: Always replace a blown fuse with a new one of the exact same amperage (A) rating and type. Using a fuse with a higher amperage can cause severe electrical damage or even a fire.

Common Blown Fuses on This Vehicle

Some common fuses that might blow on a 2015 Chevrolet Malibu include those related to:

• Cigar Lighter/12V Power Outlets: These fuses often blow due to overcurrent from charging multiple devices or using high-power accessories. If your phone charger or accessory adapter isn't working, check the relevant power outlet fuses (F3 in the Instrument Panel Fuse Block and F1 in the Rear Compartment Fuse Block).
• Headlights/Tail Lights: A blown headlight or taillight fuse can result in one or both lights not working. This can sometimes be caused by a faulty bulb or a short in the wiring. Check F6, F7, F8, F9 in the Underhood Fuse Block for headlights, and F2, F3 in the Rear Compartment Fuse Block for tail/brake lights.
• Blower Motor: If your climate control fan isn't working on any speed, the blower motor fuse might be blown (F10 in the Underhood Fuse Block). This can be a symptom of a failing blower motor or a resistor issue.
• Radio/Infotainment: If your radio or infotainment screen is completely dead, check the radio fuse (F1 in the Instrument Panel Fuse Block). Often, this can occur after a jump start or battery disconnection if there was a power surge.

When a fuse blows, it's important to understand why it blew. While simply replacing it might temporarily fix the issue, if there's an underlying problem like a short circuit or an overloaded component, the new fuse will likely blow again. If fuses continue to blow, it's best to consult a professional.
