System Description
+A heat line has been added to the lower portion of the wind-
shield.
+During cold weather, water can freeze between the wiper
blades and windshield. Turning the wiper deicer switch ON
melts the ice between the blades and windshield.
+During snowfall, packed snow can accumulate around the
windshield lower surface and surrounding areas. Turning the
wiper deicer switch ON melts the snow to allow the wiper
blades to more easily remove it.
+The wiper deicer operates only for approximately 15 minutes
while ignition switch is in ON position. The timer is combined
with wiper deicer switch.
