Wiper Arm: Description and Operation
Description
Front
FRONT
The front wiper arms are the rigid members located between the wiper pivots protruding from the cowl plenum cover/grille panel near the base of the
windshield and the wiper blades on the windshield glass. Both wiper arms feature an over-center hinge (3) that allows easy access to the windshield glass
for cleaning. The wiper arms each have a die cast metal pivot end. The left arm has a large tapered mounting hole on the pivot end that is secured by a
nut to the left wiper pivot.
The unique, articulated right wiper arm has two pivoting links attached to the arm pivot end. A drive link (5) is secured by a nut to the right wiper pivot
and is the unit that drives the right wiper arm. The articulating link (6) is secured by a nut to a drone pivot located outboard of the right wiper pivot on
the wiper module bracket. The right wiper arm pivot end and the connections of both links to the arm are concealed beneath a molded black plastic
appearance cover (4).
The wide end of a tapered, stamped steel channel (2) hinges on and is secured with a hinge pin to the blade end of both the right and left wiper arm pivot
ends. One end of a long, rigid, stamped steel strap (1), with a small hole near its pivot end, is riveted and crimped within the narrow end of the stamped
steel channel. The tip of the wiper blade end of this strap is bent back under itself to form a small hook. Concealed within the stamped steel channel, one
end of a long spring is engaged with a wire hook on the underside of the die cast pivot end, while the other end of the spring is hooked through the small
hole in the steel strap. The entire wiper arm has a satin black finish applied to all of its visible surfaces.
A wiper arm cannot be adjusted or repaired. If damaged or ineffective, the entire wiper arm unit must be replaced.
