Fuses and relays Toyota Windom (V30), 2001–2006

Table of Contents

Most electrical circuits in this Japanese sedan are protected by fuses. High-power electrical loads—such as the headlights, cooling fan motors, and fuel pump—are connected via relays. Fuses and relays are housed in distribution boxes located in the engine compartment and the passenger compartment.

Fuse diagrams apply to Toyota Windom (chassis code MCV30) models from 2001 through 2006 equipped with the 3.0L 1MZ-FE engine.
