Windshield Wipers - GMC TopKick 2007 Owner's Manual

Windshield Wipers

(Off): Turn the band on the lever to this
9
symbol to turn off the windshield wipers.
(Mist): For a single wiping cycle, turn the
8
band to this symbol. Hold it there until the wipers
start, then let go. The wipers will stop after
one cycle. If you want more cycles, hold the band
on mist longer.
You can set the wiper speed for a long or short
delay between wipes. This can be very useful
in light rain or snow. Turn the band to select the
delay time. The farther the band is turned upward,
the longer the delay will be. The farther the
band is turned downward, the shorter the delay
will be.
You control the
windshield wipers by
turning the band with the
wiper symbol on it.
For steady wiping at low speed, turn the band
toward you to the first solid band below the delay
settings.
For high-speed wiping, turn the band farther, to
the last solid band below the delay settings.
To stop the wipers, move the band to off.
Be sure to clear ice and snow from the wiper
blades before using them. If they are frozen to the
windshield, carefully loosen or thaw them. If
your blades do become worn or damaged, get
new blades or blade inserts. For more information,
see Windshield Wiper Blade Replacement on
page 314.
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 or ice
the wiper will stop until the motor cools. 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 your
windshield wipers.
