Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box, usually under the dashboard or in the engine compartment.
Remove the power window fuse using a fuse puller.
Inspect the fuse for continuity; replace it if blown with the same amperage rating.

3. Inspect and Replace Window Switch

Remove the door panel using a socket set and a flat-head screwdriver.
Disconnect the window switch connector.
Use a multimeter to test the switch for functionality; replace if faulty.

4. Test and Replace Window Motor

If the switch is functional, apply direct battery voltage to the window motor terminals.
If the motor does not operate, replace it with a new motor.
Reinstall the motor and ensure it is properly secured.

5. Check Window Regulator

Inspect the window regulator for mechanical issues such as binding or broken cables.
If damaged, remove the regulator by detaching it from the door and replacing it with a new one.
