I have a 2005 Trailblazer. The last few days when I turn it off and lock the doors (I always use the remote lock), the passlock light comes on (steady light) and all my lights come on. So I restart the car, shut it off and don’t lock the doors...passlock light does not come on. I’ve been leaving it unlocked and I really don’t want to. Why is this happening? Thank you!
