Power Window Master Switch Input
Turn ignition off. Remove driver's door panel. See DOOR PANEL under REMOVAL & INSTALLATION. Disconnect power window master switch connectors. Inspect connectors and terminals for damage, corrosion and proper fit. Repair as necessary and recheck system operation. If connectors are okay, perform appropriate power window master switch input test. See Fig 1 or Fig 2 . If all input tests are okay and power windows still do not operate properly, replace power window master switch.
