The compact MPV Ford C-Max was produced across two generations starting in 2003. The first generation was manufactured from 2003 through 2010, receiving a mid-cycle facelift during this period. The second generation was marketed from 2011 to 2019. Below is a comprehensive guide to the fuse and relay boxes for both the 1st and 2nd generations Ford C-Max (C1 and C2 platforms; codes C214 / C344), featuring photographs and circuit block diagrams. The fuse assigned to the cigarette lighter socket is highlighted in bold.
Fuse box layouts depend on the model year, and individual circuit assignments may vary depending on the vehicle's electrical equipment level.
Engine Compartment Fuse Box
The main engine compartment fuse box is located on the left side, under a protective cover.
