- Remove switch from vehicle. Using an ohmmeter or self-powered test light, clip a test probe to pin No. 6, which is grounded. See Fig 1 . Place both switches in the released (neutral) position and test for continuity between pin No. 6 and pins No. 1 through 4.

- Remove test probe from pin No. 6, and connect it to pin No. 5. With both switches in the released (neutral) position, no continuity should exist at remaining terminals.
- Push switches upward. Pins No. 1 and No. 3 should show continuity with pin No. 5. Push both switches downward. Pins No. 2 and No. 4 should have continuity with pin No. 5. If any switch does not test as indicated, replace complete switch assembly.
