Wiper Switch Continuity Test

Check wiper switch for continuity using following chart. Disconnect connector under steering column and test with self-powered test light or ohmmeter. (Ohmmeter 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 .
