Solution

1. Preparation

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

2. Inspect the Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the power window fuse using a fuse puller.
Inspect the fuse for any signs of damage. Replace if blown.
Reinstall the fuse and reconnect the battery.

3. Check the Power Window Relay

Locate the power window relay in the fuse box or relay panel.
Remove the relay and test it with a multimeter for continuity.
If faulty, replace with a new relay of the same rating (check the owner's manual for specifications).

4. Test the Window Switch

Remove the power window switch from the door panel.
Use a multimeter to check for continuity when pressing the switch.
If there is no continuity, replace the switch with a new unit.

5. Inspect Wiring Harness

Visually inspect the wiring harness connected to the window motor and switch.
Look for frayed wires or loose connections.
Repair any damaged sections or connectors as necessary.

6. Test the Window Motor

Remove the door panel to access the window motor.
Disconnect the motor connector.
Using a multimeter, check for voltage at the motor harness when the window switch is activated.
If voltage is present but the motor does not operate, replace the window motor.
If no voltage is present, trace back to the switch or relay.
