Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on the electrical system.
Tools required: socket set, multimeter, trim removal tools.

2. Fuse Replacement

Locate the fuse box (typically under the dashboard or hood).
Identify the power window fuse using the diagram on the fuse box cover.
Remove the blown fuse using fuse pullers or pliers.
Replace it with a new fuse of the same amperage.

3. Switch Inspection

Remove the door panel using trim removal tools.
Disconnect the power window switch connector.
Use a multimeter to test for continuity across the switch terminals when pressed.
Replace the switch if it shows no continuity or is faulty.

4. Motor Testing

With the door panel still removed, locate the power window motor.
Disconnect the motor connector.
Using a multimeter, check for voltage at the motor connector while activating the window switch.
If voltage is present but the motor does not operate, replace the motor.

5. Wiring Inspection

Inspect all wiring leading to the window motor for fraying or breakage.
Repair or replace any damaged wiring as necessary.
Ensure all connections are secure and clean.
