Fuse and relay finder

Type a fuse number, a circuit ("sunroof", "fuel pump", "radio") or a relay name to see what it feeds and where it is drawn.

Fuse numbers are those on the fuse box in the factory manual. "Also on" lists other fuses that share the circuit, so a circuit with several fuses can fail at any of them.

Written from the factory wiring diagrams on this site and general diagnostic practice. Voltages, resistances and pressures are typical figures, so confirm them against your car's manual. Take care with fuel, high voltage and the battery.
