and the windshield lower moulding should be as fol-

If the clearance is not in the specified range,

assembly (Fig.

Single Speed
To determine if an adjustment is required apply a
constant
downward
force of
25
ounces, parallel to the
windshield glass, at the end of the wiper arm (where
the wiper blade
is
attached to the arm). With the
25
ounce force applied pull the wiper blade away from
the windshield glass once or twice to prevent glass
friction from affecting downward movement of the
wiper arm and blade. With
this
force applied the
clearance between the tip of the wiper blade and the

Wiper Motor
Park
Switch Timing
The timing of the wiper motor park switch must
be:
(a) Late enough that the wiper arms come to rest at
the extreme lower limit of travel on dry glass.
(b) Early enough that the wiper arms do not raise
appreciably beyond the lower limit of travel on fully
wet glass.
Adjust the timing of the park switch on the wiper
motor to provide "shut off" at the lowest point of
wiper blade travel under both wet and dry glass con-
ditions.
When adjusting the timing of the variable speed
park switch, note that the variable speed motor ro-
tates in reverse at the time the park switch opens.
"Early" and "Late" directions are therefore opposite
to
single speed motors.
Wiper Parking Operation Test-
Variable Speed
(1)
Turn the instrument panel wiper switch to the
"on" position and allow the wiper system to run
through several cycles of operation.
(2)
Very slightly, after the wiper blades reach the
top of the wipe pattern, turn the wiper switch to OFF
to cause the blades to park in a one-half (95) cycle of
wiper motor operation.
