Window Switch (Master Multiple Switch)
- Remove switch from vehicle. See WINDOW SWITCH under REMOVAL & INSTALLATION. Using a self-powered test light or ohmmeter, connect one test lead to pin No. 6 (ground). See Fig 1. With both switches in neutral position, pins No. 1, 2, 3 and 4 should have continuity to pin No. 6.
- Push both window switches upward (toward window when in installed position). Both pins No. 1 and 3 should have no continuity to pin No. 6. Push both window switches downward (away from window when in installed position). Both pins No. 2 and 4 should have no continuity to pin No. 6.
- Remove test lead from pin No. 6 and connect to pin No. 5. With both switches in neutral position, pin No. 5 should have continuity only with itself. Push both window switches upward (toward window when in installed position). Both pins No. 1 and 3 should have continuity to pin No. 5.
- Push both window switches downward (away from window when in installed position). Both pins No. 2 and 4 should have continuity to pin No. 5. If any one switch does not test correctly, replace complete window switch assembly.
