Solution

1. Preparation

Gather tools and parts needed: OBD-II scanner, multimeter, socket set, screwdrivers, replacement fuses, and window switch (if necessary).
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Fuses

Locate the fuse box in the cabin or engine compartment as per the owner's manual.
Identify the specific fuse for the power windows (usually labeled).
Remove the fuse using a fuse puller or pliers and inspect it.
If blown, replace it with a new fuse of the same amperage rating.
Reconnect the battery and test the window operation.

3. Inspect and Replace Switches

Remove the door panel using a screwdriver to access the power window switch harness.
Disconnect the switch connector and test for continuity using a multimeter.
If the switch is defective, replace it with a new one by following the reverse of the removal process.

4. Test and Replace Window Motor

If the switches are functional, proceed to test the window motor.
Disconnect the motor wiring harness and connect it directly to a charged 12V battery to see if it operates.
If the motor does not work, remove it from the window regulator assembly.
Install a new window motor, ensuring it is properly aligned and secured.

5. Reassemble and Test

Reattach the door panel and ensure all clips and screws are secured.
Reconnect the battery and perform a test of all windows to confirm proper operation.
