Fuses
CAUTION Never replace a fuse with one having a higher rating or with material other than a fuse because serious damage or a fire could result.
NOTE
Fuse rating and using circuit are de-scribed on each behind the fuse box cover. The fuses are designed to melt during an overload to prevent damage to the wiring harness and electrical equipment. The fuses are located in two fuse boxes.
Passenger Compartment Fuse Box
One is located under the instrument panel behind the fuse box cover on the driver’s seat side.

Remove the cover.
-
Determine which fuse may be blown. Look at the back side of each fuse box cover.
