Switch Continuity Rear

Check the continuity between the switch terminals. Either a self-powered test lamp or an ohmmeter can be used to test a standard two-speed switch. An ohmmeter must be used to test a switch used with the interval wiper system. To detect marginal operation of the switch, move the switch lever while each reading is being taken. If the switch does not exhibit continuity or if poor continuity exists in any switch position, replace the switch.
