Solution

1. Preparation

Gather tools including a multimeter, socket set, flathead screwdriver, and pliers.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Identify the fuse related to the power windows and remove it using a fuse puller or pliers.
Inspect the fuse for any signs of damage; replace it if blown with a new fuse of the same amperage.

3. Inspect and Replace Switch

Remove the door panel using a flathead screwdriver to pry off clips and unscrew screws.
Disconnect the electrical connector from the window switch.
Use a multimeter to check for continuity across the switch terminals.
If faulty, replace the switch with a new one and reconnect the harness.

4. Test and Replace Window Motor

If the switch is functioning, locate the window motor in the door.
Disconnect the motor's electrical connector.
Apply direct battery voltage to the motor leads using jumper wires to check if it operates.
If the motor does not work, replace it with a new one by removing the mounting screws.

5. Reassemble Door Panel

Reconnect all electrical connectors and ensure there are no loose wires.
Position the door panel back onto the door frame and secure it with screws and clips.
Reconnect the battery and test the power windows for proper operation.
