2012 Enclave Fuse Diagram: A Comprehensive Guide
Find the right fuse on your 2012 Enclave using this fuse diagram
The 2012 Buick Enclave is equipped with two fuse boxes to protect the various electrical circuits throughout the vehicle. The interior fuse box is on the driver’s side of the instrument panel, behind a small trim cover. The underhood fuse box was located in the engine compartment on the driver’s side, near the battery. Use the tables in this 2012 Enclave fuse diagram to find the devices protected by each fuse.

2012 Enclave Fuse Diagram for Underhood Fuse Box
The underhood fuse box protects circuits for heavy-duty electrical systems like the starter, alternator, powertrain components, and exterior lights. The underhood fuse box diagram was printed on the underside of the lid for convenient reference.
How to find your fuse and the devices served by that fuse
There are 63 entries in the underhood fuse table. The tablet shows only 10 to speed up load time. Here’s how to find the fuse and circuit you want.
1) Change the number of entries showing (in the Show Entries Box) to 100 and scroll the list.
2) Enter the name of the component you’re searching for in the Search box.
3) Use the Next/Previous buttons at the bottom of the table
