Solution

1. Preparation

Gather all tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery cable to prevent electrical shock.

2. Inspect and Replace Door Switch

Remove Door Panel:
- Use a socket set to remove screws and clips securing the door panel.
- Carefully pry off the panel using a trim removal tool to avoid damaging clips.
Access Door Switch:
- Locate the door switch, usually found near the latch mechanism.
- Disconnect the electrical connector from the door switch.
Test the Door Switch:
- Use a multimeter to check for continuity when the switch is pressed and released.
- If there is no continuity when the switch is pressed, replace the switch.
Install New Door Switch:
- Connect the new switch to the electrical connector.
- Reinstall the door panel by aligning it and securing it back with screws and clips.

3. Check Body Control Module (If Necessary)

If the door switch replacement does not resolve the issue, inspect the BCM.
Remove any necessary panels to access the BCM located under the dashboard.
Use an OBD-II scanner to check for BCM-related codes and follow manufacturer-specific procedures for recalibration or replacement if needed.
