Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Make sure the vehicle is parked on a level surface.

2. Inspect and Replace Fuses

Tools Required: Fuse puller or pliers
Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the fuse related to the power windows (refer to the owner's manual for the exact location).
Inspect the fuse; if blown, replace it with a new fuse of the same amperage.

3. Test and Replace the Power Window Switch

Tools Required: Screwdriver, multimeter
Remove the door panel using a screwdriver to access the power window switch.
Disconnect the switch from the wiring harness.
Use a multimeter to check for continuity across the switch terminals. If faulty, replace the switch.
Install the new switch by reconnecting it to the wiring harness and securing the door panel back in place.

4. Check and Replace the Window Motor

Tools Required: Screwdriver, multimeter
If the switch is functional, access the window motor by removing the door panel.
Disconnect the motor from the wiring harness.
Test the motor directly by applying 12V power to it. If it does not operate, replace the motor.
Install the new motor, ensuring it is securely mounted and connected properly.

5. Reassemble and Test

Reattach the door panel and secure all screws.
Reconnect the negative battery terminal.
Test the power windows to ensure they operate correctly.
