Quite easy actually
You simply have to pry out the trim around the Radio, use a plastic tools to dont mark the plastic
Dont try to remove it from there because you will end up like me breaking one of the tabs (doesnt matter since everything hold thight there)
You need to go unsnap the plastic part on the passenger side, under it there a screw (the only one holding the trim) the rest is just snap, just pry it out gently
on the other side you can simply and easily unsnap the edge of the cluster trim.
its that easy, just remember to use a platic tool to pry out.. in worst case a thin flat screwdriver with tape on the tips
once the trim is out juste unscrew the climate control assembly, swap the switch and put everything back together
