The only additional recomendation that I would add to your advice, would
be to use a nozzle for compressed air to blow the dirt and dust out of the
'felt' before spraying it down with silicone spray.

Hi Todd,
Yup, that same has happened to me - rusted completely up on my '88 and I was
able to re-vamp them without problem. Pulling out the motor is the hardest
part, which isn't all that bad. But, once you get it out...
If you look at the base of the motor, the armature rides on a spherical
bearing down there where it looks like an ice cream cone :)
There are some holes that should be plugged with rubber plugs, though they
may have been removed. Take those out and spray your choice of rust
loosener, WD40, PB Blaster, whatever - it really doesn't matter.
The armature is riding only on this spherical bearing and the bearing at the
top that you can see when you remove the motor. Mine was totally rusted
solid at the bottom, but just fine at the top. Basically, you just need to
get that armature spinning free by breaking up the rust at the bottom (most
likely) and then keeping it greased. You can take the whole thing apart, or,
if you get lucky, just soak that bottom bearing for a day or so, and turn
the armature by hand. If you need to put a little wrench on the armature to
break the rust loose, that should be fine. It should spin free with just
your fingers when it is working properly.
To test it before hooking it up to the drive mechanism in the window, just
hook up the connectors and see if it spins free. Keep a paper towel around
the holes when you first start it because all that crud you sprayed in there
is going to be spraying back out again when the motor spins.
Now, take a look at your seals like Tom mentioned. Hopefully they look
pretty good and you can just silicone the "felt" (I dont' know the material,
it isn't felt...) runners along the sides and make sure the brackets that
actually support the window are properly greased where you have the plastic
slider moving up and down.
I did this to my completely non-functioning window regulator and now they
are working like new.
-Ben
