I am in the process of rebuilding some seats for my 92 NSX. I have two sets of seats and building one set of complete working seats for my car.. I am trying to rebuild one of the forward/back motion seat motors and I need to find some new brushes for the motor. Has anyone rebuilt one of these motors? If so where did you purchase the brushes? Has anyone used a motor from another 90's era model Acura? I am about to get my calipers out and measure what is left of the brushes and try to find a close match with something on ebay or an electronics part distributor, but if someone knows please share the info. I am sure there are plenty of cars that need this repair. If I can find a brush that works it should be way cheaper than a new motor from Acura..

There are a number of specialists who do electric motor restoration for classic cars. Do a Google search using the terms 'classic car electric motor repair'. You will get a number of hits.
These guys offer the service. They also offer to sell you parts - if you can figure out what part you need. Others probably also offer parts. Get out those calipers to do some measurements!

You don't need an exact fit. If you can find the correct style and a little oversize you can file the brush down to fit if you are careful.
Unless you are dealing with a corrosion or contamination problem, I am a bit surprised that your brushes are worn to the point of non operation. Unlike blower motors, seat motors tend to be low use and I would not normally expect brush wear to be what kills them. I think my seats probably get moved perhaps 3-4 times a year tops when I am doing cleaning. That said, from personal experience if your brushes really are worn down chances are the commutator is also worn and will require machining / resurfacing to accept the new brushes. Before you engage in that expense you would want to check that the windings are OK and that there is not bridging in the commutator segments which may also accompany high brush wear.
Good luck with it.

There are plenty of companies that have quite a selection of carbon motor brushes. They will even have custom services to make them up based on your sample that you send them. I'm with Old Guy, make sure that the worn brush is the root of the cause.
Go ahead, do a teardown of the motor and post pictures. I'll bet there is another seat application where you can rob parts from.
