1. Remove and inspect 20 amp fuse #9 in the fuse panel. Replace as required.
2. Remove liftgate cover, refer to Rear Window Wiper Motor Service.
3. Measure resistance between rear wiper motor connector terminal 3 and ground. Meter should read zero ohms. If not, repair wiring to ground.
4. With liftgate closed, measure resistance between rear wiper motor connector terminal 6 and ground. Meter should read zero ohms. If not, repair liftgate ajar switch and wiring as necessary.
5. Turn ignition switch to ON and place rear wiper switch in WASH. Measure voltage at rear wiper motor connector terminal 5. Meter should read battery voltage. If not, go to step 7.
6. Place rear wiper switch in ON. Measure voltage at rear wiper motor connector terminal 2. Meter should read battery voltage. If not, go to step 7.
7. Remove rear wiper switch and reconnect below instrument panel. Back probe rear wiper switch connector, with ignition switch in ON position.
8. Measure voltage at rear wiper switch connector terminal 1. Meter should read battery voltage. If not, repair open to fuse #9.
9. Push rear wiper switch to WASH. Measure voltage at rear wiper switch connector terminal 4. Meter should read battery voltage. If OK, repair open to rear wiper motor terminal 5. If not, replace switch.
10. Move rear wiper switch to ON. Measure voltage at rear wiper switch connector terminal 3. Meter should read battery voltage. If OK, repair open to rear wiper motor terminal 2. If not, replace switch.
11. Move rear wiper switch to DELAY. Measure voltage at switch connector terminal 2. Meter should read battery voltage. If OK, repair open to rear wiper motor terminal 4. If not, replace switch.
