Multiple Switch

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

Fig 1: Multiple Switch Pin Location Use ohmmeter or self-powered test lamp for test.
Push both switches upward. Both No. 1 and No. 3 should lose continuity to pin No. 6. Push switches downward. No. 2 and No. 4 should lose continuity to pin No. 6.
Remove test probe from No. 6, and connect it to feed pin No. 5. With both switches in neutral position, no continuity should exist at remaining terminals.
Push switches upward. Both No. 1 and No. 3 pins should show continuity with No. 5. Push both switches downward. Both No. 2 and No. 4 pins should have continuity with No. 5. If any switch does not test as indicated, replace complete switch assembly.
