Heater matrix removal

Could somebody put a detailed howto removing the heater matrix?

I should clean it, but I can't reach it.
Behind the gloves box, removed the bolts from big black box, removed the fan, but seems that's not enough

I have a shell stripped out il try have a look for you if i get chance as i got a busy day tomorrow but il see if i can see what still holding it .... can you pop up a pic of how far you got so i can see whats next stage ...

It's fully assembled now.
But inthe past, I tried more than three times to disassemble it, without success.

Its been ages since I took one out but if I remember correctly there was 1 or 2 bolts tucked away that I really had to search for. Also I think there is a plug on top that has some really short wiring that also needs to be removed. I had to give mine a decent pull to get it out aswell.
