Solution

1. Preparation

Tools Required: Screwdriver set, multimeter, OBD-II scanner
Disconnect the vehicle battery to ensure safety while working.
Gather necessary tools and parts before beginning the repair.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the power window fuse according to the owner's manual.
Check if the fuse is blown by visually inspecting or using a multimeter.
If blown, replace it with a fuse of the same amperage (usually 30A).

3. Test and Replace Power Window Switch

Remove the switch panel using a flathead screwdriver to gently pry it up.
Disconnect the wiring harness from the switch.
Use a multimeter to check for continuity when pressing the switch buttons.
If there is no continuity, replace the switch with a new one.
Reconnect the switch and reassemble the panel.

4. Test Window Motor

If the switch is operational, remove the door panel to access the window motor.
Disconnect the motor's wiring harness.
Using jumper wires, connect the motor directly to the battery to check for functionality.
If the motor does not operate, replace it with a new motor.
Reinstall the door panel after repairs.

5. Check Wiring and Connections

While the door panel is off, inspect the wiring harness for any frays, corrosion, or loose connections.
Repair any damaged wires using solder and heat-shrink tubing or replace the harness if necessary.
