Switch Continuity Test

Multifunction Switch:





1. Check for continuity between the switch terminals. An ohmmeter must be used to test switch used with the interval wiper system.
2. To detect marginal operation of the switch, rotate the switch control knob while each reading is being taken.
3. If the switch does not exhibit continuity, or if poor continuity exists in any switch position, replace the switch.
