Wiper Switch Component Test
Fig. 24 Wiper Switch Continuity Test:
Continuity Test
When testing a non-intermittent wiper switch, a self-powered test lamp or an ohmmeter can be used to check continuity. When testing an intermittent wiper switch, use only an ohmmeter to check continuity.
When taking test readings move the switch lever to detect marginal switch operation.
Refer to Fig. 24 for switch terminal identification and continuity readings.
