Solution

1. Preparation

• Gather tools and parts.
• Disconnect the battery to ensure safety while working on electrical components.
• Tools required: Screwdriver set, Multimeter, Torque wrench, Pliers.

2. Inspect and Replace Fuse

• Locate the fuse box, typically found under the dashboard or in the engine compartment.
• Remove the cover and locate the fuse for the power windows (refer to the label on the fuse box cover).
• Use a fuse puller to remove the fuse and check for continuity.
  • If blown, replace it with a fuse of the same amperage (e.g., 30A).
  • Reconnect the battery and test the power windows.

3. Test and Replace Power Window Switch

• Remove the door panel to access the power window switch.
  • Use a screwdriver to carefully pry off the panel without damaging clips.

• If the switch is functional, access the window motor by removing the door panel completely.
  • Detach any clips or screws holding the panel.
• Disconnect the wiring harness from the window motor.
• Test the motor by applying direct power from a battery.
  • If the motor does not operate, replace it.
