MAX position of the intermittent control switch.
If operation is not as specification, replace the
wiper switch assembly.
3) Inspect the vehicle speed response (With the
wiper switch installed on the vehicle)
(1) Operational check
Position the front wiper switch to INT, then mea-
sure the intermittent stationary time at each ve-
hicle speed.
If operation is not as specified, replace the
