Cooled/heated seats

[jagman7742]

Hi all, I've got a 05 mondeo estate ghia and was thinking of upgrading from the cloth seats to leather heated/cooled seats from the ghia x. Anyone know how I do this, other than buying some ghia x seats. My car currently has heated seats so I presume a new switch is needed, also its got the 2.2 engine if that makes any differance? Thanks.
