Checking and Replacing Fuses in Lexus GS 300 / GS 350 / GS 430

  1. Turn the ignition switch off and open the fuse box lid. Determine which fuse may be causing the problem. The lid of the fuse box shows the name of the circuit for each fuse.
  2. Pull the suspected fuse straight out with the pull-out tool and check it.
  3. Look carefully at the fuse. If the thin wire is broken, the fuse has blown. If you are not sure or if it is too dark to see, try replacing the suspected fuse with one of the same value that you know is good. If it has blown, push a new fuse into the clips. Only install a fuse with the amperage rating designated on the fuse box lid.

If the new fuse immediately blows out, there is a problem with the electrical system. Have your Lexus dealer correct it as soon as possible.

Caution!

  • Never use a fuse with a higher amperage rating, or any other object, in place of a fuse. This may cause extensive damage and possibly a fire.
  • Always use a genuine Lexus fuse or equivalent for replacement. Never install an ordinary wire – even for a temporary fix. This may cause extensive damage and possibly a fire.
  • Before replacing the fuses, have the cause of electrical overload determined and repaired by your Lexus dealer.
