Information Gathering : Climate Control in LR Focus

[nlfbt8]

Just trying to get together as much information as I can about the climate control system on an LR focus. I'm considering retro-fitting it to my partner's LR Zetec R.

A few of you have provided some information previously about needing to change the whole heating system, and not just the module at the front, which is understandable. I know that this could turn into a very expensive excercise, but I may deem it to be a worthwhile project (especially if it means this will be the only LR hatch in Aus with climate control!).

So, here is what I already know;

• I obviously need to buy the digital module for the dash
• I'll need to replace the cable controlled actuators on the heater box with the electric servo actuators
• A number of sensors will need to be installed (Sunlight, outside air temp?)
• I may need to replace the whole interior airbox
• The install will have to be able to be "uninstalled" cleanly ... or else my partner will never let me do it!

If anyone has any information at all, or even some schematics of the climate system, or photos of the original system in a Ghia sedan, it would be greatly appreciated!
