Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace Fuses

Locate the fuse box in the vehicle (usually under the dashboard or in the engine compartment).
Identify the specific fuse for the power windows using the owner's manual.
Remove the fuse and inspect it for continuity using a multimeter.
- If blown, replace it with a new fuse of the same amperage rating.

3. Test Window Switches

Remove the door panel to access the window switch assembly.
- Tools: Screwdriver set, trim removal tools
Disconnect the switch connector and use a multimeter to test for continuity on the switch terminals.
- If faulty, replace the window switch.

4. Test Window Motor

With the door panel still removed, locate the window motor.
Disconnect the motor connector and apply direct battery voltage to the motor terminals.
- If the motor operates, it may be functional; if not, replace the motor.

5. Inspect Wiring Harness

Check the wiring harness for signs of damage, fraying, or corrosion.
Repair or replace any damaged wiring as necessary.

6. Reassemble and Test

Reattach the door panel securely.
Reconnect the negative battery terminal.
Test all power windows to ensure proper operation.
