Removal and Installation of Front Wiper ArmsINFOID:0000000005395073
REMOVAL
1. Turn wiper switch on to operate wiper motor, and then turn wiper switch off (auto stop).
2. Open hood, remove wiper arm caps, and remove wiper arm nuts.
3. Raise wiper arm, and remove wiper arm from the vehicle.
INSTALLATION
1. Clean up the pivot area as shown. This will reduce possibility of
wiper arm looseness.
2. Prior to wiper arm installation, turn on wiper switch to operate wiper motor and then turn it off (auto stop).
3. Push wiper arm onto pivot shaft, paying attention to blind spline.

Component Parts and Harness Connector LocationINFOID:0000000005395084
System DescriptionINFOID:0000000005395085
• The wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. Terminal combination status is read by the BC M (body control module) when switch is turned ON.
• The BCM controls rear wiper ON and INT (intermittent) operation.
Power is supplied at all times
• through 40A fusible link (letter g , located in fuse and fusible link box)
• to BCM terminal 70.
With the ignition switch in ON or START position, power is supplied
• through 15A fuse [No. 4, located in the fuse block (J/B)]
• to combination switch terminal 2
• through 10A fuse [No. 6, located in the fuse block (J/B)]
• to BCM terminal 38.
Ground is supplied
• to BCM terminal 67, and
• to combination switch terminal 12
• through grounds M57 and M61.
REAR WIPER OPERATION
When the ignition switch is in the ON or START position, and the rear wiper switch is in the ON position, the
BCM detects a rear wiper ON request through the combination switch (wiper switch) reading function and con-
trols the rear wiper motor as follows.
Power is supplied
• through BCM terminal 55
• to rear wiper motor terminal 1.
Ground is supplied

• to rear wiper motor terminal 3
• through grounds B117, B132 and D402.
With power and ground supplied, the rear wiper motor operates.
INTERMITTENT OPERATION
The rear wiper motor operates the wiper arm at low speed approximately every 7 seconds.
When the wiper switch is in the rear wiper INT positi on, the BCM detects a rear wiper INT request through the
combination switch (wiper switch) reading function.
When BCM operates rear wiper motor, power is supplied
• through BCM terminal 55
• to rear wiper motor terminal 1.
Ground is supplied
• to rear wiper motor terminal 3
• through grounds B117, B132 and D402.
With power and ground supplied, the rear wiper operates in intermittent mode.
AUTO STOP OPERATION
When the rear wiper arm is not located at the base of the rear window, and the rear wiper switch is turned
OFF, the rear wiper motor will continue to operate until the rear wiper arm is at the base of the rear window.
When the rear wiper arm reaches the base, r ear wiper motor terminals 2 and 1 are connected.
Ground is supplied
• to BCM terminal 44
• through rear wiper motor terminal 2, and
• through rear wiper motor terminal 3, and
• through grounds B117, B132 and D402.
REAR WASHER OPERATION
When the ignition switch is in the ON or START positi on, and the front and rear washer switches are OFF, the
front and rear washer motor is supplied power
• through 15A fuse [No. 4, located in the fuse block (J/B)]
• to combination switch (wiper switch) terminal 14
• through combination switch (wiper switch) terminal 11
• to front and rear washer motor terminal 2.
When the rear wiper switch is in rear washer positi on, the BCM detects a rear washer signal by BCM wiper
switch reading function. Combination switch ground is supplied
• to front and rear washer motor terminal 1
• through combination switch (wiper switch) terminal 13, and
• through combination switch (wiper switch) terminal 12
• through grounds M57 and M61.
With ground supplied, the front and rear washer motor is operated in the rear direction.
When the BCM detects that the rear washer motor has operated for 0.4 seconds or longer, BCM operates the
rear wiper motor.
When the BCM detects that the rear washer switch is in OFF, the rear wiper motor cycles approximately 3
times and then stops.
If the rear washer is operated with the rear wiper switch in the INT position, normal rear wiper operation will
take over. Once the rear washer switch is re leased the rear wiper will return to INT operation.
