REMOVAL AND INSTALLATION
For vehicle without air bag system, refer to Section 3C COMBINA-
TION SWITCH, and for vehicle with air bag system, refer to Section
3C1 CONTACT COIL AND COMBINATION SWITCH ASSEMBLY.
Wiper Motor
1) As illustrated, use a 12 V battery to connect its (+) terminal to ter-
minal ªAº, and its (±) terminal to Black lead wire (2) (Type A, B)
or terminal ªEº (Type C).
If motor (1) rotates at a low revolution speed of 45 to 55 rpm, it
is proper. For high speed check, connect battery (+) terminal to
terminal ªBº, and its (±) terminal to Black lead wire (2) (Type A,
B) or terminal ªEº (Type C). If motor rotates at a high revolution
speed of 67 to 83 rpm, it is proper.

Intermittent Wiper Relay Circuit
1) Disconnect negative cable at battery.
2) Disconnect combination switch lead wire coupler.
3) Turn the front wiper switch to INT position.
4) Turn the intermittent time control switch to FAST position.
5) Connect battery positive terminal to terminal ªB3º and battery
negative terminal to terminal ªEº.
6) Connect voltmeter positive lead to terminal ª+1º and negative
lead to terminal ªEº.
Check that the voltmeter indicates the battery voltage (10 ±
14 V).
7) Connect terminal ªAsº and terminal ªB3º by a jumper wire. Then
move jumper wire end connected to terminal ªB3º to terminal ªEº.
Observe the voltmeter voltage drops to 0 V right after connecting
the jumper wire from terminal ªB3º to ªEº. Then the voltage rises
to battery voltage (10 ± 14 V) within the time shown in the table
below.

DEFOGGER WIRE
NOTE:

When cleaning rear window glass, use a dry cloth to wipe it
along wire direction.

When cleaning glass, do not use detergent or abrasive-con-
taining glass cleaner.

When measuring wire voltage, use a tester with negative
probe wrapped with a tin foil which should be held down on
wire by finger pressure.
1) Checking wire damage
a. Turn main switch ON.
b. Turn defogger switch ON.
c. Use a voltmeter to check voltage at the center of each heat
wire, as shown.
Voltage
Criteria
Approx. 5 VGood (No break in wire)
Approx. 10 V or 0 VBroken wire
If measured voltage is 10 V, wire must be damaged between
its center and positive end. If voltage is zero, wire must be
damaged between its center and ground.
