Fuse box diagram (fuse layout), location, and assignment of fuses and relays Cadillac Seville (1998, 1999, 2000, 2001, 2002, 2003, 2004).
Checking and Replacing Fuses
The wiring circuits in your vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of fires caused by electrical problems.
Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating.
Note
- Before replacing a fuse check that the key has been removed from the ignition and that all the services are switched off and/or disengaged.
- Always replace a fuse with one that has the specified amperage rating. Using a fuse with a higher amperage rating can cause severe wire damage and could start a fire.
- If a fuse blows again contact a qualified service center.
