Ok so i'm new to the SUV's so maybe there is something simple i'm missing? When i walk out to the truck in the dark, which is kept in the garage, I open the door and none of the interior light's come on? If the doors are locked and I unlock them with the remote the lights all come on? I don't lock the truck in the garage. From what I know most cars interior lighting comes on when you open the doors? This is the newest vehical i've ever owned so i'm thinking there is something i need to switch on for them to work? Thanks for the help. I have an 06 Suburban.
