Does anyone know what's behind this door?

Hi, purchased a 2008 3124KB. Although I paid a lot for an inspection, I'm pretty sure the guy never even looked at it, just took my money and ran. Lots and lots of work to do and this forum is a life saver!

I don't know what this door is for. (Hopefully the pic did attach below.) I can't get it opened and it appears that maybe because the latch is broken off (hence the opening in the door) but when I put my finger in the opening and feel around for a mechanism I don't find anything.

Thanks in advance!
