Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe location with the ignition off.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace the Fuse

Locate the fuse box (refer to the owner’s manual for the exact location).
Identify the fuse related to power windows (usually labeled).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for a blown filament. Replace it if necessary with a fuse of the same amperage.

3. Inspect the Window Switch

Remove the door panel to access the window switch.
- Use a screwdriver to remove screws and gently pry off the panel.
Disconnect the switch connector.
Use a multimeter to test for continuity when the switch is pressed. Replace if faulty.

4. Test the Power Window Motor

With the door panel still removed, locate the window motor.
Disconnect the motor’s electrical connector.
Use jumper wires to apply direct battery power to the motor.
If the motor operates, the issue lies elsewhere (such as in wiring or switch).

5. Examine Wiring and Connectors

Inspect the wiring harness for fraying, corrosion, or damage.
Check connectors for secure fit and clean terminals with electrical cleaner if corroded.
Repair or replace damaged wiring as necessary.

6. Reassemble and Reconnect

Reattach the door panel in reverse order of removal.
Reconnect the battery.
Test the power window operation before finalizing.
