Solution

1. Preparation

Gather tools and parts needed.
Disconnect the vehicle battery to ensure safety.

2. Check and Replace Fuse

Locate the fuse box, which is usually under the dashboard or in the engine compartment.
Identify the power window fuse (refer to the fuse diagram).
Remove the fuse and check it for continuity using a multimeter.
If blown, replace it with a new fuse of the same amperage.

3. Test Power Window Switch

Remove the door panel to access the power window switch.
Disconnect the switch connector.
Using a multimeter, check for voltage at the switch connector when the switch is activated.
If no voltage is detected, replace the power window switch.

4. Inspect Window Motor

With the door panel removed, locate the window motor.
Disconnect the motor wiring harness.
Apply direct battery voltage (usually 12V) to the motor terminals to check for operation.
If the motor does not operate, it should be replaced.

5. Check Wiring and Regulator

Inspect the wiring harness for visible damage or corrosion.
If the wiring is intact, inspect the window regulator for any mechanical issues (binding or breaking).
Replace the window regulator if necessary.
