DESCRIPTION
Each wiper blade is secur ed by an in tegr al latch ing
pivot block to th e hook formation on t he tip of t he
wiper arm , and r ests on th e glass near the ba se of
the windshield when th e wipers ar e not in oper ation
(Fig. 26). Th e wiper bla de con sists of the following
components:
• Superstructure - The su per st ructure includes
severa l sta mped st eel bridges a nd links with claw
formations that grip th e wiper bla de elemen t. Also
included in this unit is the lat ching, molded plastic
pivot block th at secures t he su perstructur e to t he
wiper ar m. All of the meta l componen ts of the wiper
blade have a satin black fin ish applied.
• Element - The wiper element or squeegee is the
resilien t ru bber member of the wiper blade tha t con-
tacts t he glass.
• Flexor - The flexor is a r igid met al componen t
running along the length of the wiper elemen t on
each side, where it is gripped by the claws of the
su perstru cture.
All Sprinter models ha ve un equal lengt h wiper
blades with n on-replacea ble ru bber elemen ts (squee-
gees). The left (driver) side wiper blade is 60.0 centi-
meters (23.5 inches), and th e r igh t (passen ger) side

worn, or damaged the en tire wiper blade un it must
be replaced.
OPERATION
The wiper bla des a re moved back and fort h across
the glass by the wiper arms when the wipers are
being opera ted. The wiper blade super structu re is
the flexible fram e t hat gr ips the wiper bla de elemen t
and even ly distribut es th e force of t he spring-loaded
wiper a rm along the lengt h of t he element. The com -
bina tion of the wiper arm force and the flexibility of
the superstru cture makes th e element conform to
and mainta in proper conta ct with the glass, even as
the blade i s moved over the varied curvature th at
may be encountered a cross t he glass surface. The
wiper elemen t flexor pr ovides the claws of th e blade
su perstru cture with a rigid, yet flexible componen t
on the elemen t wh ich can be gripped. The ru bber ele-
ment is designed to be stiff en ough to maintain an
even cleaning edge a s it is dra wn acr oss the glass,
but resilien t en ough to conform t o the glass su rface
and flip from one cleaning edge to the other ea ch
time the wiper blade changes direct ions.
