ok whilst i was doing it i took a few photos so i could show people how you go about swapping them over.

first of all to make the job easier you need to remove both the front seats and the centre console



next you need to get your head under the pedals and look up towards the back of the dash.

you will see a bracket which holds the back of the dash in place

undo the screw highlighted by the yellow arrow


there will be one of these on each side of the dash so undo the one on the passenger side too (the one on the passenger side will have a little cable bolted to it which controls the heater direction

then you need to get back under the pedals and the next picture shows the bolts you need to undo.
the green arrows are the 2 bolts which hold the heater matrix in place - undo these and put them to one side

next you need to remove as much of the ducting (orange circle) as possible so the heater 'box thing' (technical term ) is easier to move out the way.

finally you need to undo the bolts that suspend the heater 'box thing' which is shown by the red arrow in the picture. again you need to undo them on both sides



when you have undone all these bolts you need to lower the 'box thing' out the way so you can remove the heater matrix. mine was a bit of a bastard to come out but in the end it dropped out and landed in the drivers side footwell.

you may find that you need to pull it right forwards so that the heater matrix pipes clear the bulkhead. (i just broke the pipes so that they came through )

now you can withdraw the heater matrix and slide in the new one.

refitting is much easier than removal.

refit the 2 screws that hold in the heater matrix

just raise the 'box thing' and thread the heater matrix pipes up through the bulkhead.

do up the bolts that suspend it in place and bolt the brackets back onto it and refit the heater ducting.

then you just refit the seats and centre console (perfect opportunity to get the hoover out first! )



hope this comes n handy for someone!
