2. Using a Voltmeter, test for B- (ground) in the following terminals. Place the positive lead of the voltmeter in terminal 87. Briefly, touch the
voltmeter to a good ground and observe that the voltmeter reads within one volt of battery voltage. Using the negative lead of the voltmeter, test
for B- in the following terminals.
a. Terminal 85 should read within one volt of battery voltage. If OK, go to Step b. If not OK, repair the Z1 circuit (relay ground) to ground.
b. Terminal 87A should have continuity to ground when the rear window defogger switch is pressed. If OK, go to Step 3. If not OK, refer to Rear
Window Defogger Switch Test.
3. To test terminal 30 remove relay and connect a ohmmeter to the B+ connector on the left side of rear window defogger grid terminal. If there is
continuity, replace relay. If no continuity repair C15 circuit as necessary.
