Interior lights on when locked handle pulled
 

Basically the 2000 blazer I have will light up its interior when the locked door handles are pulled. Not sure if this is a common problem, kind of hard to search for via describable keywords.

Where do I start looking? Dont want to give thieves an easier time looking for something to take.

That's how my 2002 operates. The lights go back out automatically after about 30 seconds.

Yeah, I think it is part of the security system.
