Wiper Switch Continuity Test

Test Switch continuity with an ohmmeter connected between switch terminals as shown in Fig 1. To detect marginal operation of the switch, move the switch lever as each reading is being taken. If switch does not show continuity or if poor continuity exists, replace switch.
