Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Tools required: Door panel removal tool, multimeter, socket set, wire connectors (if needed).

2. Inspect Fuses

Locate the fuse box under the dashboard and in the engine compartment.
Remove the fuse for the power windows and inspect it visually for damage.
If blown, replace it with a fuse of the same amperage rating.

3. Test Window Switches

Remove the door panel using a door panel removal tool.
Disconnect the window switch connector.
Use a multimeter to check for continuity across the switch terminals while pressing the switch.
If there's no continuity, replace the window switch.

4. Check Window Motor

With the door panel removed, locate the window motor.
Disconnect the power connector from the motor.
Using jumper wires, apply direct battery power to the motor terminals to test operation.
If the motor does not work, it needs replacement.

5. Inspect Wiring

Check the wiring harness connecting the door to the body of the vehicle for any signs of wear or damage.
Repair or replace any damaged wires or connectors.
