Solution

1. Preparation

Gather tools and parts required.
Disconnect the negative terminal of the battery to avoid electrical shorts or shocks.

2. Inspect and Clean Door Switches

Tools Required: Screwdriver set, electrical cleaner, lint-free cloth
Remove the door panel covering the affected door’s switch.
- Use the screwdriver to remove screws securing the panel.
- Gently pry off the panel using a trim removal tool.
Clean the door switch with electrical cleaner.
- Spray the cleaner on the switch and wipe with a lint-free cloth.
Reinstall the door panel securely.

3. Test and Replace Door Switch

Tools Required: Multimeter, replacement door switch (if needed)
With the multimeter, set it to the continuity setting and test the door switch.
- If there is no continuity when the door is closed, the switch is faulty.
If faulty, disconnect the wiring harness from the switch and remove it.
Install the new door switch by reversing the removal process.
Reconnect the wiring harness.

4. Verify Wiring and BCM

Visually inspect the wiring harness for breaks or frays.
If damaged, repair or replace the wiring as necessary.
Check the BCM for any error codes and ensure it is functioning correctly.
