Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent any electrical short circuits.

2. Inspect and Replace Switch

Remove Door Panel:
- Use a screwdriver to remove screws securing the door panel.
- Carefully pry off the door panel using a trim removal tool to avoid damaging clips.
Access the Window Switch:
- Disconnect the wiring harness from the back of the driver's power window switch.
Test the Switch:
- Use a multimeter to check for continuity across the switch terminals. If no continuity is found when the switch is actuated, replace the switch.
Replace with New Switch:
- Install the new driver's window switch by reversing the removal steps.
- Reconnect the wiring harness securely.

3. Check Wiring and Fuses

Inspect Wiring:
- Check the wiring harness for any frays, cuts, or corrosion. Repair or replace any damaged wiring.
Test Fuses:
- Locate the fuse box and use the fuse puller to remove the fuse related to the power windows. Check for continuity. If the fuse is blown, replace it with the manufacturer-recommended fuse rating.

4. Reconnect Battery

Reconnect the negative terminal of the battery, ensuring all connections are tight and secure.

5. Reset Codes

Use the OBD-II scanner to clear any codes from the vehicle’s computer after repairs are completed.
