Solution

1. Preparation

Gather necessary tools and materials.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Check the 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 if blown (typically a 30A fuse).

3. Inspect the Relay

Identify the power window relay in the fuse box.
Remove the relay and test it using a multimeter for proper function.
Replace the relay if it does not operate as intended.

4. Test the Window Switch

Remove the switch panel using a flathead screwdriver and trim tool.
Disconnect the electrical connector from the window switch.
Use a multimeter to check for continuity between the terminals when the switch is pressed.
Replace the switch if it fails the continuity test.

5. Examine Wiring and Connections

Visually inspect the wiring harness and connectors leading to the window motor.
Look for signs of wear, fraying, or corrosion.
Repair or replace damaged wiring as necessary.

6. Test the Window Motor

If all previous steps are functional, check the window motor.
Remove the door panel to access the window motor.
Connect a multimeter to the motor terminals and apply direct battery voltage to check for operation.
Replace the window motor if it does not work when powered directly.
