Solution

1. Preparation

Gather necessary tools and parts before beginning the repair.
Tools Required: OBD-II scanner, multimeter, socket set, screwdriver set, wire strippers, and electrical tape.
Safety Warning: Disconnect the battery before working on electrical systems.

2. Check and Replace the Fuse

Sub-steps:
1. Locate the fuse box, typically found under the dashboard or in the engine bay.
2. Remove the cover and find the fuse for the power windows (refer to the owner's manual for the exact fuse location).
3. Use a fuse puller or pliers to remove the fuse and inspect it for continuity.
4. If the fuse is blown, replace it with a new fuse of the same amperage rating (check the manual for specifications).

3. Test and Replace the Window Switch

Sub-steps:
1. Remove the door panel carefully using a screwdriver and trim tool to access the window switch.
2. Disconnect the wiring harness from the switch.
3. Use a multimeter to test for continuity across the switch terminals when pressed.
4. If the switch is faulty, replace it with a new switch and reconnect the wiring.

4. Inspect and Repair Wiring

Sub-steps:
1. Inspect the wiring harness leading to the window motor for any visible damage, fraying, or corrosion.
2. If damage is found, use wire strippers to remove the damaged section and splice in new wire, ensuring proper insulation with electrical tape.
3. Reconnect any connectors and ensure they are secure.

5. Check and Replace Window Motor

Sub-steps:
1. If the motor is suspected to be faulty, remove the door panel completely to access the window motor.
2. Disconnect the motor's wiring harness and test for voltage supply when the switch is activated.
3. If no voltage is present, further investigate the wiring or switch.
4. If voltage is present but the motor does not operate, replace the window motor.
5. Reassemble the door panel after completing repairs.
