yeh the boot light is a bugger, usual story when you remove some trim, when you put it back its never quite the same! Be very careful of the clips holding it on.

I also found after drying and spraying with water displacer the usual suggestion to give the switch a wake up, it worked fine for a week or two and then gave up again! i think if it bothered me more than it does id replace the switch while i was there.
About the re circ button, just double check the air direction, as i know mine dosnt work if its upright i.e. blowing on the windscreen, just a thought!
