Heavy snow or ice can overload your wipers. The windshield wiper motor is
protected from overload by a circuit breaker and a fuse. If the motor
overheats due to heavy snow, etc., the wiper will stop until the motor cools.
Although the circuit is protected from electrical overload, overload due to
heavy snow, etc. may cause wiper linkage damage. Always clear ice and
heavy snow from the windshield before using your windshield wipers.
Windshield Washer
At the top of the multifunction lever there's a paddle marked with the
windshield washer symbol and PUSH. To spray washer fluid on the
windshield, push the paddle.
The wipers will clear the window and then either stop or return to your
preset speed.
Driving without washer fluid can be dangerous. A bad mud splash can block
your vision. You could hit another vehicle or go off the road. Check your
washer fluid level often.
