Headlights
The headlight wiring is protected by a circuit breaker in
the light switch. An electrical overload will cause the
lights to go on and off, or in some cases to remain off. If
this happens, have your headlight wiring checked right
away.
Windshield Wipers.
The windsheld wiper motor is protected
hy
a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools. If
the .overload is caused by some electrical problem and
not snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit .breakers in the fuse panel protect 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 fixed or goes
away.
Lumbar Power Seat Controls
If you have the lumbar controls for the power seat, there
is a 10 amp fuse under each seat 'wrapped in tape.
Should your
seat
ever not work, this fuse should be
checked.
