Fig. 21 6. Spacer washer
A correctly operating windshield wiper-washer
system has a spray pattern that cleans
75% of the wipe
pattern (Fig. 21) within ten wiper cycles.
If the nozzles become plugged, apply air pressure.
If nozzle remains plugged, the nozzle must be replaced.
If the spray pattern is too low or too high on the wind-
shield, wedge-type adjustment shims can be used.
Placement of a shim under the nozzle mounting bracket
will raise the pattern three degrees. Reverse installation
of the same shim will lower the pattern three degrees.
