If the fan won't open, you may need a new arm assembly. They aren't very expensive or overly complicated to replace. You can find videos on YouTube. Just make sure you find the right one. I replaced that same one last year and the arm I got was slightly different, but I was able to make it work. I clean the interior mostly with a, broom, a vacuum, and a damp cloth. I use regular carwash and a product called "The Last Coat" on the outside. I use a product from The Last Coat called, CeraTrim on the external plastic trim. I clean the roof with a bit of Dawn dish soap and a cloth
I don't have any suggestions on the window. For the time being you should always seal the crack with some silicone sealant or something, until you track down a replacement.
I hope this helps. Good luck!
