Why my interior light staying on in my car

There are a couple of possibilities... The most likely is check your headlight control to see if the dimmer switch has been turned all the way up and activated the interior lights. The other likely possibility is that you have a door switch that is not working and the car thinks the door is always open.

If neither of these are occurring, the likely prospect is a wiring issue. These are best handled by an experienced mechanic so... it's a possible trip to the shop.

Best of luck.
