Solution

1. Preparation

Gather tools including a socket set, multimeter, and flathead screwdriver.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace the Window Switch

Use a flathead screwdriver to gently pry off the switch panel from the door.
Disconnect the electrical connector from the window switch.
Use a multimeter to check for continuity across the switch terminals. If defective, proceed to replace.
Install the new switch by connecting the electrical connector and snapping the switch panel back into place.

3. Test and Replace the Power Window Motor (if needed)

Remove the door panel using a socket set to access the power window motor.
- Unscrew any fasteners and carefully detach clips holding the door panel.
Disconnect the wiring harness from the power window motor.
Apply direct power to the motor using jumper wires from a 12V battery. If the motor does not operate, it requires replacement.
Remove the old motor by unscrewing it from the window regulator and installing the new motor by reversing the process.

4. Check and Replace Fuses

Locate the fuse box, usually found under the dashboard or the engine compartment.
Identify the fuse related to the power windows (refer to the fuse diagram).
Use a fuse puller to remove the suspect fuse and inspect it for continuity. Replace with a fuse of the same amperage if blown.

5. Reassemble the Door Panel

Once repairs are complete, reattach the door panel by aligning it and pressing it back into place.
Reinstall all fasteners removed during disassembly.
Reconnect the negative battery terminal.
