Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box under the dashboard or in the engine compartment.
- Tools Required: Fuse puller or needle-nose pliers.
Check the power window fuse(s) for continuity. If blown, replace with a fuse of the same amperage (refer to the owner’s manual for specifications).

3. Test and Replace Window Switches

Remove the door panel to access the window switch assembly.
- Tools Required: Screwdriver set, trim removal tool.
Disconnect the switch harness and test for continuity using a multimeter.
If faulty, replace the window switch with a new one.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness for any fraying, cuts, or disconnections.
If damage is found, repair the wiring using appropriate connectors and electrical tape.

5. Check Window Motors

With the door panel removed, test the window motor by applying direct battery voltage to it.
- Safety Warning: Be cautious of moving parts and ensure the window is not obstructed.
If the motor does not operate, replace with a new motor.

6. Reassemble and Test

Reattach the door panel and ensure all clips and screws are secured.
Reconnect the battery and test all power windows for proper operation.
