Solution

1. Preparation

Gather necessary tools: multimeter, screwdriver set, trim removal tools, and a replacement fuse if needed.
Disconnect the negative terminal of the battery to prevent electrical shorts during repairs.

2. Inspect and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the power window fuse using the diagram.
Pull the fuse using a fuse puller and check for continuity. If blown, replace with a fuse of the same amperage rating (usually 30A for power windows).

3. Test 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 and test it using a multimeter for continuity.
If the switch is faulty, replace it with a new switch by reversing the removal process.

4. Check the Wiring and Connections

Inspect the wiring harness for any visible damage, fraying, or corrosion.
Ensure all connectors are securely attached and in good condition. Repair or replace any damaged wiring as needed.

5. Test the Window Motor

If the switch and fuse are functional, locate the window motor inside the door.
Connect a multimeter to the motor terminals and activate the window switch. Check for voltage.
If there is voltage but the motor does not operate, it may need to be replaced. If there is no voltage, trace back to the switch and wiring for faults.
