Ok , I will try to guide you as simple as I can :
1- Remove the Heater / Cooler unit this is how : * Disconnect Battery ground cable
* Recover AC gas or empty it in open space
* Drain radiator coolant only
* Remove instrument panel for access
* From under the hood disconnect AC pipes at the evaporator , by removing bolts , discarding O-Rings and make sure to install blanking plugs so that no dirt goes in.
* Disconnect heater hoses from heater matrix pipes , by releasing the spring band clips and make sure to blank the pipes
* From inside the car , remove driver footwell duct , by removing the screw and then removing the duct
* Remove upper steering column lower fixing , nuts and bolts
* Remove upper steering column upper fixings (Bolts) , and allow column to rest down o the floor
* Cut cable tie which secures console harness to LH blower duct
* Remove LH fan motor duct (screws)
* Remove passenger side footwell vent (nut)
* Cut cable tie securing console harness to RH blower duct.
* Remove RH fan motor duct (screws)
* Disconnect Heater/Cooler Connector
* Disconnect drain tubes from Heater/cooler assembly
* Disconnect A/CCM connectors
* Remove evaporator pipe support bracket fixing.
* Remove Heater/Cooler assembly fixing , by removing lower nut and upper nut
* Remove tape securing RH rear footwell intermediate duct joint. Remove duct to clear access
* Remove tape securing LH rear footwell duct
* Remove Heater/Cooler assembly from car.

2- Remove AC control module 3- Remove evaporator pipe seal plate 4- Disconnect heater tempreture sensor 5- Remove footwell servo motor from heater/cooler unit * Disconnect connector
* Remove screws
* Remove motor complete with bracket
6- Disconnect evaporator sensor connector * Detach heater/cooler connector
* Detach evaporator sensor connector
* disconnect connector
7- By now you can see one upper and one lower case * Remove heater/coolent unit upper case from lower case
* Remove screw
* Remove 15 clips
* Remove upper case from lower
8- Remove evaporator from case * Remove sensor and clip

You are done , make sure to replace all seals that you see to make sure that every thing is ok and you do not have any leaks after installation.
Installation : Reverse order and after installing make sure to do a pressure test to make sure that there are no leaks
