Solution

1. Preparation

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

2. Check and Replace Fuses

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the power window fuse (check the owner's manual for location).
Remove the fuse and inspect it for a break in the wire.
If blown, replace it with a fuse of the same amperage.

3. Inspect and Replace Window Switches

Tools Required: Screwdriver set
Remove the trim panel around the window switch using a flathead screwdriver.
Disconnect the switch connector and remove the switch from the panel.
Test the switch with a multimeter for continuity.
If faulty, replace it with a new switch and reassemble the trim panel.

4. Test and Replace Window Motors

Tools Required: Socket set, multimeter
Remove the door panel to access the window motor. Use a socket set to remove screws and clips.
Disconnect the motor connector and test it with a multimeter for voltage with the switch pressed.
If there is no voltage, the switch may be faulty. If voltage is present but the motor does not operate, replace the motor.
Install the new motor and reassemble the door panel.

5. Check Wiring and Connections

Inspect the wiring harness for any frays or damage.
Repair any damaged wires with solder or appropriate connectors.
Ensure all connections are tight and free of corrosion.
