Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety during repairs.
Tools Required: Multimeter, socket set, trim removal tools, wire connectors.

2. Check and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the power window fuse using the diagram on the fuse box cover or the owner's manual.
Remove the fuse using pliers or a fuse puller.
Inspect the fuse for continuity using a multimeter. If blown, replace it with one of the same amperage.

3. Inspect and Replace Window Switch

Remove the trim panel around the window switch using trim removal tools.
Disconnect the electrical connector from the switch.
Test the switch with a multimeter; if faulty, replace it with a new switch.
Reconnect the new switch and reassemble the trim panel.

4. Test and Replace Window Motor

Remove the door panel to access the window motor, following manufacturer guidelines for disassembly.
Disconnect the window motor from the wiring harness.
Test the motor by connecting it directly to a battery; if it does not operate, replace the motor.
If the motor works, inspect the regulator and other components for any mechanical obstructions.

5. Reassemble and Test

Reattach the door panel and ensure all screws and clips are secured.
Reconnect the battery.
Test the power windows to confirm they are functioning correctly.
