When I had a W210 car, the blower motor regulator blew up. I believe it is a common problem on a W210 (my car was MY 2000, a face lift one). Do you have automatic AC? The display was showing the adjusted blower speed but the blower was first going up and down a bit on its own and finally started blow at full speed, on its own.
The odd thing to me is that at least the face lift model did not have any fuse for the blower motor. I could not believe this but an (independent) expert confirmed this. I had to disconnect the battery because the car had to wait for the spare part over night (the blower would have run the battery flat during the night otherwise).
I've seen DIY guides for the regulator job but did not do any search at this time.
