Evaporator removal help

I am pretty new to this forum and maybe this topic has been discussed before, but I honestly don't know where to start from. Well, I recently purchased 1995 C280 and I love it. This is my first Mercedes, so I don't know much about it. Just wondering do I need to remove the whole dashboard to reach the evaporator on my C280? I don't have the owner/repair manual so need your help on this topic.

All your inputs are warmly welcome.
