210 HVAC test procedure
 

Somebody please point me toward the test procedure (evaluation of each component) for the MB 210 HVAC

Your best bet it probably to pick up a W210 service manual from the classic center. I haven't seen any online ones.

It looks like they are only $25?

Here is the code readout procedure, if that's what you wanted:

that didn't prove to be successful. their attempts to restart production of the
210 DVD was fraught with quality control problems with very few (if any)
proving to be playable. I managed to score one (from earlier reproduction) and
fully functional.

this DVD is simply a bunch of SDS pages corralled and morphed into a standalone, hyperlinked interface.
