Could anybody please tell me what is the quickest way of removing the heater matrix on the 'B' series van? My previous van was an Astramax and the centre console could be removed quite easily to access the matrix unlike this Combovan which seems to be all moulded into one with the dashboard. It looks to be a ball-ache, is that true? If so, have I got to strip out the dashboard top to access the matrix or am I missing an easier way?

A combo b is based of the corsa c, but thats irrelevant atm, take a pic of the dash just so I know what it is
