Chevy Equinox Interior Lights Won't Turn Off
Interior lights that stay on after every door is closed almost always trace back to a door jamb switch the body control module thinks is still open, though wiring damage and a stuck dome light switch are also common culprits.

Check for a Timeout First
Give the vehicle 10-20 seconds after closing all doors, since most Equinox models have a built-in delay timer before the interior lights shut off on their own.
Door Jamb Switch Issues
If the lights stay on with all doors confirmed closed and the manual light switch set to off, the vehicle likely thinks a door remains open due to a faulty or misaligned door jamb switch, most commonly on the passenger side. Test each door by opening and closing it a few times to see if it affects the light, and inspect the switch for debris, corrosion, or physical damage; cleaning or lightly lubricating it often resolves an intermittent switch.
Dome Light Switch
If door switches all test fine, inspect the dome light's own control switch, since a stuck or damaged switch there can cause constant power flow to the light regardless of door status.
Wiring Problems
In some documented cases, a melted ground wire in the interior lighting harness kept power flowing to the map lights at all times; if switches test fine, a wiring inspection with a multimeter for continuity issues is the next step.

| Dome light switch | Inspect switch for sticking or damage |
| Wiring harness | Check continuity with a multimeter |
Frequently Asked Questions
Will this drain my battery if I don't fix it?
Yes — lights left on continuously, especially overnight, can drain the 12-volt battery, so it's worth addressing promptly rather than letting it run indefinitely.
Can I just disconnect the light as a workaround?
You can temporarily pull the bulb or fuse to stop the drain, but that only masks the underlying door switch or wiring issue rather than fixing it.
Which door is usually the culprit?
The passenger door jamb switch is the most frequently cited culprit in owner reports, though any door switch can be responsible.
Is this covered under warranty?
A faulty door switch or wiring defect is often covered if your Equinox is still within its factory warranty period, so check with your dealership before doing DIY repairs on a newer vehicle.
