Front Door Courtesy Light Control Switch 💡🚪
This front door courtesy light control switch is a small but critical electrical part that tells the cabin light when to turn ON or OFF as you open and close the front door. It’s needed for safe entry at night, quick cabin visibility, and proper operation of the interior light delay and “door” mode.
How It Works ⚙️
The switch is mounted at the door area and uses a spring-loaded contact. When the door closes, the plunger/contact changes position and opens or closes the circuit. That signal is sent to the body control system/interior lamp circuit, which powers the courtesy lamp and can also trigger door-ajar warnings on some trims.
Symptoms When It Fails ❗
- Cabin light stays ON and drains the battery 🔋
- Courtesy lamp won’t come ON when the door opens
- Intermittent light flicker over bumps
- Random “door open” indication (where equipped)
Why Replace It ✅
A worn contact, corrosion, or weak spring can cause poor electrical continuity. Replacing the switch restores correct lighting behavior, prevents overnight battery drain, and keeps the interior lamp system working as designed.
