Fuses and Circuit Breakers
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 damage
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.
There are four fuse blocks in your vehicle: the main and
auxiliary instrument panel fuse blocks, the underhood
fuse block and the rear fuse block.
Main and Auxiliary Instrument Panel
Fuse Blocks
The main and auxiliary instrument panel fuse blocks are
located under the instrument panel, on the passenger's
side of the vehicle. Lamps, connectors and the
HVAC duct temperature sensors may need to be
disconnected and removed to allow access to these
fuse blocks.Remove the hush panel on the passenger's side to
reveal the fuses by performing the following steps:
1. Remove the two screws located along the front
edge of the panel.
2. Lower the hush panel.
3. Remove the fuse block cover.
4. Place the wide end of the fuse puller over the
plastic end of the fuse.
5. Squeeze the ends over the fuse and pull it out.
When ®nished, reinstall the fuse block cover and
the hush panel. Reinstall lamps, connectors and HVAC
duct temperature sensors if they were removed.
