Headlamp Wiring
5W LL-T
An electrical overload may cause
1157
the lamps to go on and off, or in
some cases to remain off. Have the
headlamp wiring checked right away

Vehicle Care
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.
Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using the
windshield wipers.
If the overload is caused by an
electrical problem and not snow or
ice, be sure to get it fixed.
