So, you slide the door open, and it's supposed to catch on a hook there by
the rear door frame.  Well, the hook on my van is a bit loose, and has
settled such that it lies below the part it is meant to grab.  With the
door open, I can tap it up with a finger, and it catches just fine.

It is attached with a couple of Phillips head screws, but they are obscured
by the door.  How does one reach these screws to tighten them?

Thanks in advance,
