I don't know of anybody rebuilding motors these days other than industrial motor companies and some small vacuum shops. Might try one of those if no better options come your way. Or a junkyard.

1990 300SE "Corinne"- 145k daily driver - street modified differential - PARTING OUT OR SELLING SOON - PORTLAND OR. AREA - PM ME FOR DETAILS
1988 560SEL "Gunther"- 190K passes anything except a gas station
1997 S420 - 265k just bought it with a rebuilt trans. Lovely condition

What's wrong with it. Two things come to mind:

1. Bearings (probably need grease)
2. Brushes worn out
3. (Probably fabulously rare) nichrome "resistance cage" attached to blower (in the plug) has opens

In case 1, it is VERY difficult to get actual grease (NOT WD-40, light oil, etc, which actually washes away what little real grease is left and will make things "Better" only temporarily) on the bearings, but it IS doable with wire and some ingenuity.

In case 2, the brushes are held in with clips, and need to be resoldered in with a fairly heavy-duty higher-wattage soldering iron. You can get away with (for a while) stretching the springs a bit (not recommended) if a good part of the brushes are still there. Mercedes Source sells the brushes; I think it would be possible to reshape brushes you can get at a good hardware store, but for $25 or so, this might not be worth the trouble.

Case 1 costs almost nothing and an hour if you have the blower out already; case 2 costs $5-$40 and a few hours, depending on what you have and what you get.
