Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery cable to ensure safety.
2. Inspect and Replace Fuse
  • Locate the fuse box (typically found under the dashboard or in the engine compartment).
  • Identify the fuse for the power windows using the diagram.
  • Remove the fuse using fuse pullers and inspect it for continuity.
    • Tools Required: Fuse puller or needle-nose pliers.
  • If blown, replace it with a fuse of the same amperage.
3. Test Window Switch
  • Reconnect the negative battery cable.
  • Remove the door panel to access the window switch.
    • Tools Required: Screwdrivers, trim removal tools.
  • Disconnect the window switch connector and test for continuity across the terminals using a multimeter.
  • If faulty, replace the window switch with a new one.
4. Inspect Wiring and Connectors
  • While the door panel is removed, visually inspect the wiring harness for any signs of wear, fraying, or corrosion.
  • Clean any corroded connectors with electrical contact cleaner and reconnect.
5. Test Window Motor
  • If issues persist, remove the window motor from the door.
    • Tools Required: Socket set.
  • Apply direct voltage from a battery to the motor terminals to check for functionality.
  • If the motor does not operate, replace it with a new unit.
