CAUTION: Never use compressed air to flush the washer system plumbing. Compressed air pressures are
too great for the washer system plumbing components and will result in further system damage. Never use
sharp instruments to clear a plugged washer nozzle or damage to the nozzle orifice and improper nozzle
spray patterns will result.
INSPECTION - FRONT WIPER & WASHER SYSTEM
WIPER SYSTEM
The wiper blades and wiper arms should be inspected
periodically, not just when wiper performance prob-
lems are experienced. This inspection should include
the following points:
1. Carefully inspect the wiper blades for any indica-
tions of worn or uneven edges (1), foreign material
deposits (2), hardening or cracking (3), deformation
or fatigue (4), or splitting (5). Inspect the wiper
blade support components and the wiper arms for
damage (6) or corrosion. If the wiper arms and
blades are contaminated with any foreign material,
clean them and the glass as required. (Refer to 8 -
ELECTRICAL/FRONT
WIPERS/WASHERS

CLEANING). If a wiper blade or arm is damaged,
or if corrosion is evident, replace the affected wiper
arm or blade with a new unit. Do not attempt to
repair a wiper arm or blade that is damaged or cor-
roded.
2. Carefully lift the wiper blade off of the glass. Note
the action of the wiper arm hinge. The wiper arm
should pivot freely at the hinge, but with no lateral
looseness evident. If there is any binding evident in
the wiper arm hinge, or there is evident lateral play
in the wiper arm hinge, replace the wiper arm.
CAUTION: Do not allow the wiper arm to spring back against the glass without the wiper blade in place or
the glass may be damaged.
3. Once proper hinge action of the wiper arm is confirmed, check the hinge for proper spring tension. Remove the
wiper blade from the wiper arm. Either place a small postal scale between the blade end of the wiper arm and
the glass, or carefully lift the blade end of the arm away from the glass using a small fish scale. Compare the
scale readings between the right and left wiper arms. Replace a wiper arm if it has comparatively lower spring
tension, as evidenced by a lower scale reading.
4. After cleaning and inspecting the wiper components and the glass, if the wiper blade still fails to clear the glass
without smearing, streaking, chattering, hazing, or beading, replace the wiper blade.
WASHER SYSTEM
The washer system components should be inspected periodically, not just when washer performance problems are
experienced. This inspection should include the following points:
1. Check for ice or other foreign material in the washer reservoir. If contaminated, clean and flush the washer sys-
tem. (Refer to 8 - ELECTRICAL/FRONT WIPERS/WASHERS - CLEANING).
2. Inspect the washer plumbing for pinched, leaking, deteriorated, or incorrectly routed hoses and damaged or dis-
connected hose fittings. Replace damaged or deteriorated hoses and hose fittings. Leaking washer hoses can
sometimes be repaired by cutting the hose at the leak and splicing it back together using an in-line connector
fitting. Similarly, sections of deteriorated hose can be cut out and replaced by splicing in new sections of hose
using in-line connector fittings. Whenever routing a washer hose or a wire harness containing a washer hose, it
