System Description
WIPER OPERATION
The rear wiper switch is controlled by a ring built into the combination switch.
There are two wiper switch positions:
+ON (LO speed)
+INT (Intermittent)
With the ignition switch in the ON position, power is supplied
+through 10A fuse (No.
18, located in the fuse block)
+to rear wiper motor terminalj
4, and
+to rear wiper ampli®er terminalj
5.
Low speed wiper operation
Ground is supplied to rear wiper switch terminalj24through body grounds.
When the rear wiper is placed in the ON position, ground is supplied
+through rear wiper switch terminalj
22
+to rear wiper relay terminalj6.
Then ground is supplied
+to rear wiper motor terminalj
1
+through rear wiper ampli®er terminalsj2andj3.
With power and ground supplied, the wiper motor operates.
Auto stop operation
With the rear wiper switch turned OFF, rear wiper motor will continue to operate until wiper arm reaches rear
window base.
When wiper arm is not located at base of rear window with rear wiper switch OFF, ground is supplied
+to rear wiper motor terminalj
1
+through rear wiper ampli®er terminalsj2,j7and
+through rear wiper motor terminalj
3, in order to continue rear wiper motor operation at low speed.
Ground is also supplied
+to rear wiper motor terminalj
2
+through body grounds.
When wiper arm reaches base of rear window, rear wiper motor terminalsj
3andj4are connected instead
of terminalsj
2andj3. Rear wiper motor will then stop wiper arm at the PARK position.
Intermittent operation
The rear wiper motor operates the wiper arm one time at low speed at an interval of approximately 7 sec-
onds.
When the rear wiper switch is placed in the INT position, ground is supplied
+to rear wiper ampli®er terminalj
1
+through rear wiper switch terminalj21.
Then the rear wiper motor operates intermittently in the same manner as the low speed wiper operation.
WASHER OPERATION
With the ignition switch in the ACC or ON position, power is supplied
+through 10A fuse (No.
18, located in the fuse block)
+to rear washer motor terminalj
2.
When the ring is turned WASH position, ground is supplied
+to rear washer motor terminalj
1, and
+to rear wiper ampli®er terminalj
4
+through terminalj23of rear wiper switch.
With power and ground is supplied, the rear washer motor operates.
The rear wiper motor operates when the ring is turned to WASH position for one second or more and for
approximately 3 seconds after the ring is released. This feature is controlled by the rear wiper ampli®er in the
same manner as the low speed wiper operation.
REAR WIPER AND WASHER
EL-145

System Description
The rear window defogger system is controlled by the smart entrance control unit. The rear window defogger
operates only for approximately 15 minutes.
Power is supplied at all times
+to rear window defogger relay terminalj
3
+through 15A fuse (No.43, located in the fuse and fusible link box) and
+to rear window defogger relay terminalj
6
+through 20A fuse (No.44, located in the fuse and fusible link box).
With the ignition switch in the ON or START position, power is supplied
+to the rear window defogger relay terminalj
1and
+to smart entrance control unit terminalj
12
+through 7.5A fuse [No.8, located in the fuse block (J/B)].
Ground is supplied to terminalj
2of the rear window defogger switch through body grounds.
When the rear window defogger switch is turned ON, ground is supplied
+through terminalj
1of the rear window defogger switch
+to smart entrance control unit terminalj
8.
Terminalj
9of the smart entrance control unit then supplies ground to the rear window defogger relay termi-
nalj
2.
With power and ground supplied, the rear window defogger relay is energized.
Power is supplied
+through terminalsj
5andj7of the rear window defogger relay
+to the rear window defogger.
The rear window defogger has an independent ground.
With power and ground supplied, the rear window defogger ®laments heat and defog the rear window.
When the system is activated, the rear window defogger indicator illuminates in the rear window defogger
switch.
Power is supplied
+to terminalj
3of the rear window defogger switch
+from terminalj
5of the rear window defogger relay.
Terminalj
4of the rear window defogger switch is grounded through body grounds.
