So my dome light works when it wants to. But the past two mornings have been a little different. When I open the door all interior lights flash on and off. I get in shut the door and they shut off completly. When the dome light is switched off it's off. When switched on it's on. When switch is in the center is when this happens. Now when I put the truck in reverse the lights (interior) flicker. I then put the truck in drive, they flicker once more and that's it until the next morning. Any advice would be appreciated.

 

sounds factory to me
