Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools required: Screwdriver set, multimeter, wire strippers, and electrical tape.
Disconnect the negative battery terminal to ensure safety during electrical work.

2. Inspect and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and identify the power window fuse using the diagram on the fuse box cover.
Use a multimeter to check the continuity of the fuse.
- If the fuse is blown, replace it with a new fuse of the same amperage (typically 30A).

3. Check Window Switches

Remove the door panel using a screwdriver to access the switch assembly.
Disconnect the electrical connector from the power window switch.
Test the switch for continuity using a multimeter; if faulty, replace the switch.

4. Test the Power Window Motor

Access the power window motor by removing the door panel and the plastic moisture barrier.
Disconnect the motor's electrical connector.
Using a direct power source, connect the motor to the battery to see if it operates.
- If the motor does not work, it needs to be replaced.

5. Inspect Wiring and Connections

Check the wiring harness for damage or wear, focusing on areas where the harness bends, such as at the door hinge.
Repair any damaged wires using wire strippers and electrical tape.
Ensure all connectors are securely plugged in.

6. Reassemble Door Panel

Reattach the moisture barrier if it was removed.
Align the door panel and press it back into place, ensuring all clips are secured.
Reconnect the window switch and test the operation of the windows before finalizing the installation.
