My interior lights are working intermittently. They started flashing randomly when the doors were open and are to the point now where the don't even work. I have had water (sunroof drain) issues in the past which have long been fixed, but I think now there is corrosion to a module or relay above the headliner on the passenger side.

Does anyone know what the name of that module or relay is called? Trying to find a replacement. When the lights are not working, I can actually hear a noise from that area. If I turn the lights off by holding the center button for 5 seconds, that noise goes away.
