I have a Laramie with Keyless Enter 'n Go. Most of the time I want to open or close the door without the truck lighting up like a jukebox. The Illuminated Entry system can be turned off by rotating the dimmer control to the far left, but the Cargo Lamp still comes on. The initial setting of the Cargo Lamp switch does not matter. If I do nothing the lamp stays on for 30 seconds. How do I make the lamp come on only when I want and not every time I use the door?
