Car Forum / Mercedes-Benz Cars / March 2005Power Window Motor Rebuild?
It figures that my window would die right after asking questions about it! Has anyone attempted to replace the brushes in a 300SD power window motor? I'd hate to pay for a new motor if it's possible to pop a set of brushes in it. >It figures that my window would die right after asking questions about it! > >Has anyone attempted to replace the brushes in a 300SD power window motor? > >I'd hate to pay for a new motor if it's possible to pop a set of brushes >in it. Don't see why not. Where are you gonna get brushes? There's three versions, 8 tooth, 10 tooth and 14 tooth. These can be as cheap, used, as $32. http://car-parts.com  SignatureNeed Mercedes parts ? - http://parts.mbz.org http://www.mbz.org | Mercedes Mailing lists: http://lists.mbz.org 633CSi 250SE/C 300SD | Killies, killi.net, Crypts, aquaria.net 1970 280SE, 72 280SE | Old wristwatches http://watches.list.mbz.org Ace Hardware has a big slection of brushes..

The failure rate is VERY low. > It figures that my window would die right after asking questions about it! > > Has anyone attempted to replace the brushes in a 300SD power window motor? > > I'd hate to pay for a new motor if it's possible to pop a set of brushes > in it. I agree... majority of time is just the window switches needed to be cleaned out internally.. specifically oxidation of 6 electrical contact points. How can you tell if its a motor? I replaced the switch on mine but it still does not work. > How can you tell if its a motor? I replaced the switch on mine but it still > does not work. Isolate the motor and see if you can make it go with external power. You should also check your relay.

If it turns, it aint the motor.
