1. Prior to wiper arm installation, turn on wiper switch to operate
wiper motor and then turn it “OFF” (Auto Stop).
2. Lift the blade up and then set it down onto glass surface to set
the blade center to clearance “L1” & “L2” immediately before
tightening nut.
3. Eject washer fluid. Turn on wiper switch to operate wiper motor
and then turn it “OFF”.
4. Ensure that wiper blades stop within clearance “L1” & “L2”.
●Tighten wiper arm nuts to specified torque.
●Before reinstalling wiper arm, clean up the pivot area as illus-
trated. This will reduce possibility of wiper arm looseness.

HEADLAMP WASHERPFP:28620
System DescriptionEKS0036H
The headlamp washer is controlled by the headlamp washer timer. With power and ground supplied, the head-
lamp washer motor operates.
Power is supplied at all times
●through 30A fusible link (letter E, located in fuse and fusible link box)
●to headlamp washer motor terminal 1, and
●through 10A fuse (No. 31, located in fuse and fusible link box)
●to lighting switch terminal 11.
With ignition switch in the ON or START position, power is supplied
●through 10A fuse [No. 11, located in fuse block (J/B)]
●to headlamp washer timer terminal 4.
Ground is supplied to headlamp washer timer terminal 5 through body grounds E24 and E50. When headlamp
washer switch is pushed during lighting switch is in 1st or 2ND position, ground is supplied
●to headlamp washer timer terminal 6
●through headlamp washer switch and body grounds M27 and M70, and
●to headlamp washer motor terminal 2
●through headlamp washer timer terminal 2.
