1. Check intermittent wiper relay terminal voltage with relay energized.
2. Connect a voltmeter between terminal No. 3 and ground.
3. If voltmeter indicates zero voltage, check wiper switch.
4. If voltmeter indicates 12 volts, check intermittent wiper relay.
5. If voltmeter changes between zero volts and 12 volts repeatedly, system is operating satisfactory.
