Solution

1. Preparation

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

2. Inspect and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the power window fuse (check your owner's manual for the exact location).
Inspect the fuse for continuity; replace if blown with one of the same amperage.

3. Test and Replace Window Switches

Remove the switch panel using a flathead screwdriver to carefully pry it up.
Disconnect the electrical connectors from the switch.
Use a multimeter to check for continuity across the switch terminals when pressed.
If faulty, replace the switch with a new one.

4. Check Wiring and Connectors

Visually inspect the wiring harness leading to the window motor for any signs of wear or damage.
Clean any corrosion from connectors using electrical contact cleaner.
Repair or replace any damaged wires or connectors.

5. Test or Replace Window Motors

Remove the door panel to access the window motor (use a socket set to remove screws).
Disconnect the motor’s electrical connector.
Test the motor using a direct power source (e.g., a 12V battery) to see if it operates.
If the motor does not work, replace it with a new one.
