Wiper Switch Continuity Test

Test switch continuity with an ohmmeter connected between switch terminals as shown in Fig. 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.
