snow or ice, the wiper will stop until the motor cools.
If the overload is caused by some electrical problem,
have it xed.
Fuses and Circuit Breakers
The wiring circuits in the vehicle are protected from
short circuits by fuses and circuit breakers. This greatly
reduces the chance of circuit overload and re caused
by electrical problems.

instrument panel fuse block.
To identify and check fuses, circuit breakers, and relays,
refer to the Fuse Usage Chart on the inside surface
of the fuse panel door.
