- Check wiper fuse. If fuse is blown, inspect Blue wire between fuse block and wiper switch, and between fuse block and wiper motor for short to ground. If wire is okay, replace fuse and go to next step. Repair Blue wire if it is shorted.
- Perform WIPER SWITCH TEST. If switch is okay, go to next step. Replace switch if defective.
- Perform WIPER MOTOR TEST. If motor is okay, go to next step. Replace motor if defective.
- Unplug 14-pin connector from wiper switch. Turn ignition on. Check for battery voltage at Blue wire at harness connector. If battery voltage exists, go to next step. If battery voltage does not exist, repair Blue wire to fuse block.
- Measure resistance between Black wire at harness connector and ground. If resistance is less than 5 ohms, go to next step. If resistance is not less than 5 ohms, repair Black wire to ground.
- Turn ignition off. Unplug wiper motor connectors. Turn ignition on. Check for battery voltage at Blue wire at harness connector. If battery voltage exists, repair Black wire(s) between wiper motor connector(s) and ground. If battery voltage does not exist, repair Blue wire to fuse block.
