Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, trim removal tool, and electrical cleaner.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical short circuits.

2. Inspect and Replace the Window Switch

Remove the door panel using a trim removal tool to access the window switch.
Disconnect the wiring harness from the switch.
Test the switch with a multimeter for continuity. If faulty, replace with a new switch.
Reconnect the switch and reassemble the door panel.

3. Check and Replace Fuses

Locate the fuse box and identify the power window fuse (refer to the owner's manual for the correct fuse number).
Inspect the fuse; if blown, replace it with a fuse of the same amperage.
Reconnect the battery and test the power windows.

4. Test and Replace the Window Motor

Remove the door panel to access the window motor.
Disconnect the motor's wiring harness.
Test the motor by connecting it directly to the vehicle battery; if it does not operate, replace the motor.
Install the new motor and reconnect the wiring harness.

5. Inspect and Replace the Window Regulator (if necessary)

If the motor tests good but the window still does not operate, inspect the window regulator.
Remove the motor from the regulator assembly.
Check for any mechanical binding or damage; if damaged, replace the window regulator.
Reinstall the motor onto the new regulator and secure it in place.
