Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shock or short circuits.

2. Check and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the power window fuse using the diagram on the cover or the owner's manual.
Use a multimeter to test the fuse for continuity. If blown, replace it with a fuse of the same amperage.

3. Inspect and Repair Wiring

Examine the wiring harness leading to the window switch and motor for any signs of wear, fraying, or disconnection.
Repair any damaged wires using appropriate wire connectors and electrical tape.
Ensure all connectors are securely plugged in.

4. Test and Replace Window Motor (if necessary)

If the motor is suspected to be faulty, remove the door panel using a socket set.
Disconnect the motor wiring harness and test the motor with direct power from a battery.
If the motor does not operate, replace it by unscrewing the mounting bolts and reversing the installation steps with a new motor.

5. Reassemble and Reconnect Battery

Once repairs are complete, reattach the door panel and ensure all clips and screws are secured.
Reconnect the vehicle battery and test the window operation.
