Relay Test
Turn Signal/Hazard Relay:
See page 23-172
Normally-open type:
1. Check for continuity between the terminals.. There should be continujty between the No. 1 andNo.3 terminals when power and ground are con-nected to the No. 2 and No. 4 terminals.. There should be no continuity between the No. 1and No. 3 terminals when power is disconnected.

Wipers/Washers
Rear Wiper Motor Test (Hatchback)
1.Remove the hatch lower trim panel (see section 20).
Disconnect the 4P connector from the wiper motorassemDry,
Test the motor by connecting battery power to theNo. 1 terminal and ground to the No. 3 terminal.
lf the motor does not run or fails to run smoothly,reptace rI.
Reconnect the 4P connector to the wiper motor.
Connect an analog voltmeter between the No. 4 (+)
and No.2 (-)terminals,
Run the motor by turning the wiper switch ON.
The voltmeter should indicate 0 V and 4 V or lessalternately.

)Actuator Test
't.Disconnect the actuator cable from the actuator rod
and the 4P connector.
Connect battery power to the No 4 terminal and
ground to the No. 1, No. 2 and No. 3 terminals.
Connect a vacuum pump to the vacuum hose Then
apply vacuum to the actuator.

5. With voltage and vacuum still applied, try to pull the
actuator rod out by hand. You should not be able to
oull it out. ll you can, it is defective
1.
Disconnect ground from the No.3 terminal. The actu-
ator rod should return lf it does not return, but the
vent hose and filter are not plugged, the solenoid
valve assembly is defective.
Repeat steps 2 through 5, and disconnect ground
from the No. 1 terminal. The actuator rod should
return. lI it does not return, but the vent hose and
filter are not plugged. the solenoid valve assembly
is defective.
It you replace the solenoid valve assembly, be sure
to use new O-rings on each solenoid.
Disconnect power and ground from the 4P connector.
Disconnect the vent hose from the actuator. Connect
a vacuum pump to the actuator vent hose port, and
apply vacuum. The actuator rod should pull in com-
pletely. lf not, the vacuum valve is stuck open.
Replace the actuator'
