Front Wiper Relay Test: Previa

1. Ensure wiper motor operation is correct. See FRONT WIPER MOTOR TEST . If motor operates correctly when tested separately from switch, check wiper switch and front wiper relay. See FRONT WIPER SWITCH TEST . For front relay location, see Fig 1.
2. Check front wiper relay. Using an ohmmeter, check continuity between relay terminals No. 1 and 4. See Fig 2. No continuity should exist. Connect ohmmeter leads to relay terminals No. 1 and 3. Continuity should exist. If continuity is not as described, replace relay.
