Master Window Switch
- Remove master window switch from vehicle. See WINDOW SWITCH under REMOVAL & INSTALLATION. Use a self-powered test light or ohmmeter to test window switch. With master window switch in neutral position, there should be continuity between terminals No. 1, 3, 4, 5 and 6. See Fig 1.
- When ribbed potions of master switch rocker knobs are pushed (to close windows), continuity should exist between terminals No. 1, 2, and 3 and terminals No. 4, 5 and 6.
- When flat portions of master switch rocker knobs are pushed (to open windows), continuity should exist between terminals No. 1, 3, and 5 and terminals No. 2, 4 and 6. If master switch does not test as specified, replace master window switch.
