Solution

1. Preparation

Gather tools and parts needed for repair.
Tools Required: Fuse puller, multimeter, socket set, screwdrivers, wiring harness repair kit (if needed).
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use the fuse puller to remove the power window fuse (check the owner's manual for the exact location).
Inspect the fuse for continuity using the multimeter. If blown, replace it with a new fuse of the same amperage (usually 30A).

3. Test and Replace Switches

If the fuse is intact, proceed to remove the door panel using a screwdriver to access the window switch.
Disconnect the window switch connector and test it with a multimeter for continuity.
If the switch is faulty, replace it with a new switch and reconnect it.

4. Inspect Wiring and Connections

Check the wiring harness leading to the window motor for any signs of wear or damage.
Repair any damaged wires using a wiring harness repair kit, ensuring all connections are secure and insulated.

5. Test Window Motor

If the switches and wiring are functional, remove the door panel to access the window motor.
Disconnect the motor connector and test the motor by applying direct battery power to it.
If the motor does not operate, replace it with a new window motor.
