First of all remove the fascia form the heater control panel. I use my Leatherman blade to prise it off from one side and then the other.
Note: If your car is from 1995 to 2000, with the round three big knobs on the heater, you’ll need to remove them first, by just pushing them firmly.
Undo all four screws
The Heater Control Unit is also secured by this clip on that slot. To remove the Heater Control Unit you need to push it in slightly and it will prise off easily. Pay attention when you put everything back together as you must make sure you secure it back the correct way.
There are two connectors plugged in the Heater Control Unit. Best way to remove it is to push it in diagonally and unclip the first connector.
You can then remove the Heater Control Unit partially outwards and unplug the second connector

Hi,
Is it possible to change the older unit with the 3 big knobs (and the temperature switch between the vents) to these “newer”, cleaner ones?
Thanks in advance.

No, it’s not possible.

This repair becomes much easier if you pull the radio out and remove the lower face plate.
