I tried to figure out how to clean the AC system, therefore I removed the blower motor, but didn't see a good way to get to the evaporator. Is there a video or guide how to do it?
All depends on why you think you need to clean it.
If you have a musty odor from the AC, there are products you can spray in there. Used to do it when I worked for a dealership.
If its more than that, then yea, you are pulling the dash.
The oder when I switch on or off is very annoying. I know from other manufactures, you sometimes have to pull a plug or make a hole somewhere to get in front of the evaporator to clean it.

We have a chemical cleaner that gets sprayed into the evaporator drain. It goes in as a foam and sits for a few minutes. Does a great job. Then there is a cleaner spray that does get sprayed through the outside vents.
