DIAGNOSIS AND TESTING - POWER WINDOWS

WARNING: REFER TO RESTRAINTS BEFORE ATTEMPTING ANY DOOR, SEAT, STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.

Before any testing of the Power Window System is performed, the battery should be fully charged. All the wiring harness connectors should be inspected and cleaned, if necessary, to ensure good connections.

1. If both of the power windows are inoperative, check Fuse 19 in the Underhood Accessory Fuse Block.

2. With the dome lamp on, apply the power window switch in the direction of the failure.

3. If the dome lamp dims, the window track may be jammed. Check for obstructions in the guide tracks or worn weatherstrips causing a binding.

4. If the dome lamp does not dim, proceed with testing of the individual power window system components and circuits. For complete Power Windows System diagnosis, refer to Power Windows Electrical Diagnostics.
