Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, Phillips screwdriver, and a trim removal tool.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the fuse for the power windows, checking it for continuity using a multimeter.
If the fuse is blown, replace it with a new one of the same amperage (usually 30A for power windows).

3. Test and Replace Power Window Switch

Remove the door panel using a trim removal tool and screws.
Disconnect the power window switch connector.
Use a multimeter to test for continuity across the switch terminals when pressed.
If continuity is not present, replace the power window switch with a new one by disconnecting the old switch and connecting the new one.

4. Inspect Wiring and Connections

Visually inspect the wiring harness for any signs of wear, fraying, or disconnection.
Repair any damaged wires with electrical tape or replace the harness as needed.

5. Test and Replace Power Window Motor

Locate the power window motor, usually found inside the door panel.
Disconnect the motor connector.
Apply direct battery power to the motor terminals using jumper wires; if the motor does not operate, replace it.
To replace, remove the motor from the regulator using appropriate tools, install the new motor, and reconnect.
