Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Fuse

Locate the fuse box under the dashboard or engine compartment.
Identify the power window fuse using the fuse diagram.
Remove the fuse with a fuse puller and inspect it for continuity; replace it if blown.

3. Test and Replace Window Switch

Remove the door panel to access the window switch.
Unplug the switch connector and use a multimeter to test for continuity.
If the switch is faulty, replace it with a new switch by reversing the removal steps.

4. Inspect Wiring and Connections

Visually inspect the wiring harness for any signs of fraying or damage.
If damaged, repair the wiring using solder and heat-shrink tubing or replace the wiring harness if necessary.

5. Test and Replace Window Motor

If the switch is operational and the wiring is intact, test the window motor directly.
Remove the door panel to access the motor, disconnect it, and apply direct battery voltage to test the motor.
If the motor does not operate, replace it by unbolting it from the door and installing a new motor.

6. Reassemble and Test

Reconnect all components and reassemble the door panel.
Reconnect the negative battery terminal.
Test the power windows to ensure proper operation.
