If the headlights or other electrical components do not
work and the blade type fuses are O.K., check the
cartridge type fuses. If any of the cartridge type fuses are
blown, they must be replaced.

are designed to blow before the entire wiring harness is
damaged.

overload determined and repaired by your Lexus dealer.
