Solution

1. Preparation

Tools Required:
- Socket set
- Multimeter
- Screwdriver set
- Wire stripper/crimper
Disconnect the battery negative terminal to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and locate the power window fuse.
- Sub-steps:
  1. Check the fuse visually; replace if it appears blown.
  2. Replace with a new fuse of the same amperage (typically 30A for power windows).

3. Test Master Window Switch

Remove the trim panel around the master window switch.
- Sub-steps:
  1. Unscrew any screws securing the panel.
  2. Carefully pry off the panel using a trim removal tool.
  3. Disconnect the wiring harness from the master switch.
  4. Use the multimeter to test for continuity across the switch terminals.
  5. Replace the switch if it fails the continuity test.

4. Inspect Wiring and Connectors

Visually check the wiring harness leading to the power windows.
- Sub-steps:
  1. Look for frayed wires, corrosion, or loose connections.
  2. Repair or replace damaged wiring as necessary.
  3. Ensure all connectors are securely attached.

5. Test Window Motors

If the master switch tests functional, check the individual window motors.
- Sub-steps:
  1. Remove the door panel to access the window motor.
  2. Disconnect the motor's wiring connector.
  3. Use a jumper wire to apply direct power to the motor (positive and negative).
  4. If the motor operates, replace the switch or wiring; if not, replace the motor.
