Windshield
Wiper
Biade
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
.
See
611
Wipers
and
Washers

The

The

the
hood

and
the

rods
should
be
lubricated
with
SAE
30

.
Lubricate
the
seat
runners
with
multipurpose

.
Do
not
apply
any
oil
to

.
If
door
weatherstrips
are
sticking,
lubricate
them
with
silicone
spray
or
talcum
powder
.
The

should
be
lubricated
as
well
.
The
use
of

spraysshould
be
kept
to
an
ab-
solute
minimum,
as
the
alcohol
in
the
de-icer
will

out
of
the
lock

and
may
cause
the

to
corrode
internally,
or

Waxing
For

apply
a
hard
wax
after
thecar
has
been
washed
and
dried
.
Use
carnauba
or
synthetic
based
products
.
Waxing
is
not
needed
after
every
washing
.
You
can
tell
when
waxing
is
required
by
looking
at
the
finísh
when
it
is
wet
.
If
the
water
coats
the
paint
in
smooth
sheets
instead
of
forming
beads
that
rol¡
off,
a
new
coat
of
wax
is
needed
.
Wax
shouldnot
be
applied
to
black
trim
pieces,
rub-
ber,or
other
plastic
parts
.
Polishing
Use
paintpolish
only
if
the
finish
assumes
a
dull
lock
after
long
service
.
Polish
can
beused
to
remove
tar
spots
and
tar-
nish,
but
afterwards
a
coat
of
wax
should
be
applied
to

and
Trim
Leather
upholstery
and

should
be
periodically
cleaned
using
a
slightly
damp

or

The
idea
is
to
get
rid
of
the
dirtin
the
creases
and
pores
that
can
cause
brittleness
and
premature
aging
.
On
heavily
soiled
areas,
usea
mild
deter-
gent
(such
as
Woolite®)
or
other
specially
formulated
leather

.
Use
two
tablespoons
to
one
quart

water
.
Dry
the
