Windshield

Maintenance
Common
problems
with
the
windshield
wipers
include
streaking
or
sheeting,
water
drops
after
wiping,
and
blade
chat-
ter
.
Streaking
is
usually
caused
when
wiper
blades
are
coated
with
road
film
or
car
wash
wax
.
Clean
the
blades
using
soapy
water
.
If
cleaning
theblades
does
not
cure
the
problem
then
they
should
be
replaced
.
BMW
recommends
replacing
the
wip-
er
blades
twice
a
year,
before
and
after
the
cold
season
.
Onold-
er
cars,
check
the
tension
spring
that
holds
the
wiper
to
the
glass
.
Replace
the
wiper
arm
if
the
springs
are
weak
.
Drops
that
remainbehind
after
wipingare
caused
by
oil,
road
film,
or
diesel
exhaust
coating
the
windshield
.
Use
an
alcohol
or
ammonia
solution,
or
a
non-abrasive
cleanser
to
clean
the
windshield
.
Wiper
blade
chatter
may
be
caused
by
dirty
or
worn
blades,
bya
dirty
windshield,
or
by
bentor
twisted
wiper
arms
.
Clean
the
blades
and
windshield
as
described
above
.
Adjust
the
wiper
arm
so
that
there
is
even
pressure
along
the
blade,
and
so
that
the
blade
is
perpendicular
to
the
windshield
atrest
.
Lubricate
the
wiper
linkage
with
a
light
oil
.
The
linkage
is
located
under
the
hood
on
the
drivers
side
.
If
the
problem
persists,
theblades
are
excessively
aged
or
worn
and
should
be
replaced
.
