Wiper Switch Continuity

Check wiper switch for continuity using WIPER SWITCH CONTINUITY TEST. Disconnect connector under steering column and test with self-powered test light or ohmmeter. An ohmmeter is required for intermittent wiper test. If switch does not show required continuity, or poor continuity exists in any position, replace switch.

NOTE: See wiper switch connector terminal identification in Fig. Fig 1 .
