Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify and remove the power window fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if it is blown with one of the same amperage rating.

3. Test and Replace Power Window Switch

Remove the switch panel from the door by gently prying it up with a plastic trim tool.
Disconnect the electrical connector from the switch.
Use a multimeter to check for continuity across the switch terminals. Replace the switch if it is faulty.
Reconnect the switch and reassemble the switch panel.

4. Inspect Wiring and Connections

Remove the door panel to access the wiring harness.
Check for any frayed or broken wires; repair or replace as necessary.
Ensure all connections are secure and free from corrosion.

5. Test and Replace Power Window Motor

If the switches are functioning, test the power window motor:
- Disconnect the motor from the wiring harness.
- Use jumper wires to connect the motor directly to the battery (positive and negative) to check if it operates.
If the motor does not operate, replace it with a new one:
- Remove any screws or bolts securing the motor.
- Install the new motor and reconnect the wiring harness.
