FUSE PANEL LOCATION

The electrical system is protected against shorts by fuses that are designed to fail to prevent damage to the wire harness. The main fuse/relay box is located in the engine compartment. If a fuse is blown, locate the cause before replacing the fuse. Spare fuses are contained in the fuse block. A separate relay box can be found under the back seat for convertible models. On vehicles with 8 valve engine, an additional relay box is located in front of the left front wheelhouse.
