System Check

Observe window operation while operating all switches. If all power windows are inoperative, see ALL WINDOWS INOPERATIVE  under SYSTEM TESTS. If only driver power window is inoperative, test driver power window motor. See POWER WINDOW MOTOR  under COMPONENT TESTS. If drives auto-down feature is inoperative, but all other power window functions are okay, replace Driver Door Module (DDM). See POWER WINDOW SWITCH  under REMOVAL & INSTALLATION. If any individual passenger power window does not operate, see ONE WINDOW INOPERATIVE  under SYSTEM TESTS. If any power window switch operates window up and down but switch LED is inoperative, replace appropriate power window switch.
