Sorry to here of the family's loss. My condolences for your loss. The white board on the wall, shows you had priorities set where to spend the time. Somethings are more important.
You have time until you get it. I would remove light panel and clean. It will save you some PMS. No the other kind. Naval Term, Periodic maintenance System.
Before you go tearing into every thing. You could have a bad dimmer sw. Check for power on both sides of the fuse. Then remove light panel and clean where I show the rust. Apply dielectric grease. The screw on the light panel are the final ground.
So How did I know, you were going to be having problems With you cluster light. I guess you were to involved with The NSS issue.
I was working on mine and it is more than likely you have the same problem. Go read this.
