One Window Inoperative

NOTE: Window glass must be free to slide up and down for power window motor to function properly. If glass is not free to move up and down, motor will overload and trip the circuit breaker.

Place window glass halfway between up and down positions. Verify glass can be moved slightly from side to side, front to rear, and up and down. If glass does not move freely, check window glass, tracks and regulator for sticking, binding or improper adjustment. Repair as necessary and recheck system operation. If driver's door is inoperative, check motor. See POWER WINDOW MOTOR . If Auto-Down is inoperative, but all other functions are okay, replace driver door switch. If a switch LED is inoperative, but all other functions are okay, replace switch.

Disconnect negative battery cable. Remove power window switch from door with inoperative window. See POWER WINDOW SWITCH under REMOVAL & INSTALLATION. Connect negative battery cable. Turn ignition on. Check for battery voltage at power window switch harness connector. If battery voltage does not exist, repair open circuit to master window switch. If battery voltage exists, go to next step.
Check power window switch continuity. See POWER WINDOW SWITCH under COMPONENT TESTS. Replace faulty switch as necessary. If switch is okay, go to next step.
Check for continuity in each circuit between switch for inoperative window and motor. See WIRING DIAGRAMS . If continuity does not exist in any circuit, repair open circuit as necessary. If continuity exists in all circuits, test power window motor. See POWER WINDOW MOTOR under COMPONENT TESTS.
