2012 Malibu Fuse Box Diagram: Exploring the Fuse Boxes

2012 Malibu Fuse Box Diagram: Find the correct fuse for the circuit

The 2012 Malibu has three fuse boxes; an underhood fuse box, an instrument panel fuse box, also called the Body Control Module (BCM), and a rear compartment fuse box . The engine compartment fuse box is located on the driver’s side of the engine compartment and covered with a lid to protect the fuses against water splash. For this reason, always reinstall the cover after working on the fuse box. The instrument panel fuse box is located under the dash on the passenger side of the vehicle. You’ll find the rear compartment fuse box in the trunk on the driver’s side of the vehicle. To access this fuse box, remove the panel cover. This post shows the 2012 Malibu fuse box diagram for both boxes, BCM and the circuits covered for each fuse

Find the most commonly replaced fuses here

The fuse box diagram and table below show all 62 fuses and all the relays. But most DIYers are looking for fuses and relays for the lights, power ports, and the blower motor. I’ve listed the most commonly checked/replaced fuses here to save time. I’ve also listed the most commonly replaced bulbs. A blown fuse or bulb are the two most common reasons for lighting issues.

Instrument panel fuse box/Body Control Module = BCM, Underhood fuse box = UFB, Rear Compartment Fuse Box = RCFB

• Backup Light: Fuse #17 RCFB
• Blower Motor: Fuse #79 20A BCM
• Headlight Low Beam Passenger Side: Fuse #9 10A UFB
• Headlight Low Beam Driver’s Side: Fuse #7 10A UFB
• Headlight High Beam Passenger Side: Fuse #12 10A UFB
• Headlight High Beam Driver’s Side: Fuse #11 10A UFB
• Horn: Fuse #8 15A UFB
• Stop/Turn/Brake: Fuse #47 10A UFB
• Parking lamps: Fuse #6 10A RCFB

Power Windows: Driver’s Door Module Fuse #25 30A PCFB, Passenger Door Module Fuse #26 30A PCFB. Rear Windows 30A circuit breaker PCFB and Fuse#23 10A PCFB

A note about fuses, battery power and keep alive memory

If you disconnect the battery or remove the PCM fuses from the fuse box, the PCM will lose its adaptive memory and baseline throttle body position. You can avoid this by providing backup power using a jumper pack and an inexpensive OBDII cable. See this article for more information on providing backup power to prevent the loss of adaptive memory. Or, you can perform a throttle body relearn procedure and then drive the vehicle so it can relearn the new adaptive memory settings. See this article for instructions on how to perform a 2012 Malibu throttle body relearn procedure.
