Plenty of places to buy replacement brushes, and grease is easy to come by.

This information is almost correct. What it leaves out is that M-B does NOT sell the correct regulator for the car.
To use the regulator that the dealer sells, you need a new blower motor and mounting plate. Sorry, I didn't obsolete the parts, but it will increase the bill by $500 or so.
It IS possible to buy a new 140 regulator (not just any, be sure to search for the correct number), cut off the wires, cut off the wires on your old dead 210 regulator, and make one that works both electrically and physically.
