I have a 2003 suzuki xl7 that I've been running for 10 years. The door sensor is wacky now and is on almost all the time. It reacts when I'm driving and when I park is always on.
I've tried to get some basic info about this- I haven't yet done it but I could check on the individual door sensors (I think?) In any case, I assume I could do something to fix the sensor problems but haven't looked into it much yet.
In the meantime, I'm just wondering- will it be bad for the car or the battery if the light is on all the time? I can't imagine that it takes that much energy but you never know. Would it be bad if I never did anything about it?
