Solution

1. Preparation

Tools Required: Socket set, multimeter, OBD-II scanner, wire stripper, and electrical tape.
Disconnect the negative battery terminal to ensure safety before working on electrical components.

2. Check and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the power window fuse using a fuse puller and inspect it.
If the fuse is blown, replace it with a new fuse of the same amperage (typically 30A for power windows).

3. Repair or Replace Switch

If the fuse is intact, remove the door panel using a socket set to access the power window switch.
Disconnect the switch connector and test for continuity with a multimeter.
If faulty, replace the power window switch with a new one.

4. Inspect Wiring and Connectors

Check the wiring harness for any frayed wires or loose connections.
Repair any damaged wires with electrical tape or replace the affected wiring.
Ensure all connectors are securely fastened.

5. Test the Window Motor

If the switch and wiring are functional, disconnect the window motor from the regulator.
Use jumper wires to connect the motor directly to the battery (positive to positive, negative to negative).
If the motor does not operate, it will need to be replaced.

6. Replace Window Regulator (if necessary)

If the motor works but the window is still inoperative, remove the window regulator from the door.
Follow the manufacturer’s specifications to install a new window regulator if needed.
