are wiper motors difficult to rebuild?

It depends on what is wrong. If its just worn brushes then its pretty easy to rebuild.
But if the windings are fried and you have to rewind with new wire, that could take a while.

you can rewind a motor by hand? Doesn't that at least require a
fixture?

Depends a lot on the motor design. For some AC motors you can rewind the
field coil in place. For most smaller motors you have to build some kind
of fixture, which can be as easy as cutting something out of plywood.

Doing the armature is a different story altogether and that can be done
in place, but it is no fun at all and it's not worth the time to do it.

Audel's Handbook of Small Motors gives a lot of useful information on doing
your own motor rewinding. It's actually kind of fun.

First you need to find out what needs to be rebuilt. Are the bushings
loose?

I can understand that it is fun to learn to do something new, but I would
think that the
cost of the copper wire, the time involved, and the propensity to failure
would offset
the savings. A friendly wrecking yard is the amateur mechanic's best friend
at times.

Or a local starter and alternator shop. A lot of those guys are willing to
rebuild small DC motors for reasonable prices.

If you can still get parts at a wrecking yard, your car isn't old enough.

Probably true, in a lot of cases.

A '95 vintage is a prime candidate for junk yard parts round here. Not
to sure of the supply of Lumina's in the trash heap but I would give
it a shot. Getting a little harder if older than the '80's and usually
harder to find parts for very current models. To prepare yourself ask
if the yard has a cross reference guide. It will tell you what years
and models of cars will have a wiper motor to fit your car. The yard I
use charges me $1 to tell me this info. There are probably several
models of Chevy made for somelike 10 years that use the same wiper
motor. Or take the broken motor with you. If you do that make sure you
have the part marked on your way in or they will not know you brought
it with you and want to charge you for it when you leave.
