Power Windows and Other Power
Options
A circuit breaker in the instrument panel fuse block
protects the power windows and other power
accessories. When the current load is too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is xed.
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 res
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.
