Sounds like a faulty headlight on-off switch.

If you push that button, the dome light inside of the truck won't come on when you open the door.

Thia dome light comes in assembly and more than likely you need to replace it....
Either one of the door switches is broken or the dome light switch on the dash is turned on.
When the dome light stays on in an slk320 one of several things could be causing it. A door switch could be bad, the manual light switch could be stuck, or the light relay could be stuck. Any of these could cause the problem.
Most likely the fuse is blown for the dome light on the Silverado if the light doesn't come on.
Put the dome light switch on door located on the headliner to the side of the light
try looking at the swithes located where you door hinges are one of them might be shorted out causing your dome light to stay on.
Keep messing with the headlight switch, the dome light should come on depending on the car model.
Yes it is located in the locking mechanism.
Yes it does. It takes at least 15min as long as the key is in off position. I have left dome light on a few times on my '05. It will come on after you turn the key to on position and start it like a reset. Dome light will also go out same way if a door is not closed all the way. Prevents drained battery.
