Solution

1. Preparation

Gather tools and materials.
Disconnect the negative battery terminal to prevent electrical shorts.
Tools Required: Socket set, flathead screwdriver, Phillips screwdriver, multimeter, wiring harness connectors.

2. Inspect and Replace the Fuse

Locate the interior fuse box, usually found under the dashboard on the driver's side.
Identify the power window fuse using the diagram on the fuse cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace if blown with a new fuse of the same amperage (usually 30A).

3. Test Window Switches

Remove the door panel to access the window switch.
Disconnect the switch connector and test for continuity using a multimeter while pressing the switch.
If the switch is faulty, replace it with a new unit. Reassemble the door panel after replacing.

4. Inspect Wiring and Connectors

Check the wiring harness for any signs of wear, fraying, or corrosion.
Repair any damaged wires with solder and heat shrink or replace the entire harness if necessary.
Ensure connectors are clean and properly seated.

5. Test and Replace the Window Motor

If voltage is present at the motor connector but the motor does not operate, remove the motor from the door assembly.
Inspect the motor for damage; if faulty, replace it with a new window motor.
Reinstall the motor, ensuring it is securely mounted and connected.

6. Reassemble and Test

Reattach the door panel and ensure all clips are secured.
Reconnect the negative battery terminal.
Test all windows to ensure they function correctly.
