Questions from a new owner

[Jetlag]

Just bought a 07 Yukon Denali and am looking for some answers/help.

First the backlight in my overhead sunroof tilt button is not working, is this internal to the switch or can it be replaced if so how?

Second does anyone have a part # for the grommets that hold the cover on top of the intake?

Lastly, after the engine cools the lower radiator hose is collapsed. Loosening the cap on the recovery tank releases the vacuum and the hose returns to normal. Don't remember this on any other vehicles, any thoughts? Thanks in advance.

I've started seeing the coolant hoses collapse when the engine cools a lot more now. Even on some fire engines I drive. Mechanics say its fine.
