Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to prevent electrical shock.
2. Inspect and Replace Fuses
  • Locate the fuse box using the owner’s manual.
  • Identify the fuse for the power windows and remove it using a fuse puller.
  • Inspect the fuse for continuity; replace it if blown with a fuse of the same amperage.
3. Test and Replace Window Switches
  • Remove the door panel using a socket set and trim removal tools.
  • Disconnect the switch connector and test the switch for continuity using a multimeter.
  • If faulty, replace the window switch with a new part.
4. Check Wiring Harness
  • Visually inspect the wiring harness for any frayed wires or corrosion.
  • Repair any damaged wires by soldering or replacing the affected section of the harness.
5. Test and Replace Power Window Motors
  • If the switches and fuses are operational, test the power window motors.
  • Disconnect the motor connector and apply a direct 12V supply to the motor to test functionality.
  • If the motor does not operate, remove it from the door assembly and replace it.
