Internal Power Distribution Center
The Power Distribution Center is located under the drivers
side instrument panel. This center contains cartridge fuses,
micro fuses, relays, and circuit breakers. A description of
each fuse and component may be stamped on the inside
cover, otherwise the cavity number of each fuse is stamped
on the inside cover that corresponds to the following chart.
CAUTION!
• When installing the power distribution center cover, it is important to ensure the cover is properly positioned
and fully latched. Failure to do so may allow water to
get into the power distribution center and possibly
result in an electrical system failure.
• When replacing a blown fuse, it is important to use only a fuse having the correct amperage rating. The use
of a fuse with a rating other than indicated may result
in a dangerous electrical system overload. If a properly
rated fuse continues to blow, it indicates a problem in
the circuit that must be corrected.
