Please please, did someone ever see how the heater control panel can be removed/replaced?

First: I checked thoroughly the forum - I am not the first one to ask the question, however the real answer was never found, seems.
I found that
-you do not need to remove the panel to change the bulbs of it - you can pray off the front of it only, then remove the light ducts and access the bulbs.
-The heater panel has some white bits that are behind the mask, and even if unscrewed, you can not move the panel a bit.
-Removing that mask seems not easy: It seems to kind of ripple - you need to remove other masks first. I removed the radio, the ashtray, the centre beam sidings, the gear-stick panel, but I resigned when found it seems I need to remove the whole co-pilot side front drawer...

Should I let this on pros, or there is some trick? Was I just one step away from getting there?

Thanks a lot.... Roman

Just a self reply:

Removing the panel seems to be areal nightmare, however I finally found that I do not need to: The fan speed switch can be replaced from front, without removing the panel. I posted a guide with pics about it.
