Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Tools Required: Socket set, Torx screwdriver set, multimeter.

2. Check and Replace Fuses

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the power window fuse (refer to the diagram on the fuse box cover).
Inspect the fuse for continuity. If blown, replace it with a new fuse of the same amperage.

3. Replace the Power Window Switch

Remove the door panel using a Torx screwdriver.
Disconnect the electrical connector from the power window switch.
Remove the switch from the panel.
Install the new switch by connecting the electrical connector and securing it in place.

4. Inspect and Replace the Window Motor

With the door panel still removed, locate the window motor.
Disconnect the motor connector and test it with a multimeter for voltage when the switch is pressed.
If it does not receive power, further investigate wiring issues; if it does receive power but does not operate, replace the motor.
To replace, remove the mounting screws and detach the motor from the window regulator assembly.
Install the new motor and secure it with screws.

5. Inspect and Replace the Window Regulator

If the window motor functions but the window does not move, the regulator may be faulty.
Disconnect the window motor and carefully remove the regulator assembly.
Inspect for any broken cables or mechanical failures.
Replace the regulator if any damage is observed.
Reinstall the regulator and motor, ensuring all screws are tightly secured.
