After taking it apart (the old motor) I confirmed it was the brushes.
However, I couldn't find a set to fit and they were not designed to be
replaced but could be if you could make or find a set of that size.
Great thread here.
BTW, carbon brushes are very soft. You can buy oversize and sand down to
fit. Solder in and go. Even works for alternators.
Yes, I saved the old motor. I'm going to play with it and try to buy
some brushes that are close and see if I can shave then down and get
it going. I'll have one in reserve since it fits either vehicle and I
haven't had to change the 90 yet. When I get time and while I'm doing
it and if it works I may take some pictures and see about putting it
on the site you maintain.
Problem with a fix like this for me is I rarely have time to avoid
buying a part and making a quick fix. Any repair that requires
thought, research and fabrication usually takes too long. Both these
old Hondas are away at college and they generally limp in for me to
make a quick fix and are gone in a flash. :~)
But hopefull, what I've learned may help someone else.

Frank-
I opened up the motor and the brushes were both "used up"
as far as they could go, with one side worn slightly further from
the armature than the other. Looking back, this seems to make sense now.
The last time that I noticed that this radiator fan was working properly,
was after I did a slow 15 hour overnight charge on my battery. I'll bet
that the fully charged battery had enough juice to overcome the distance
between the worn out brushes and the armature, allowing the fan to turn.
So, if your radiator fan only works immediately after charging your
battery to the max, there might be a good chance that the brushes are
worn out.
I found a new motor on eBay for $36 (shipping included) and I'll pop it in
when it gets here. Thanks for sharing your insight. It was a big help.

Gary, I just replaced the motor on my AC fan (95 Accord) I don't know
if the radiator FAN and AC FAN are installed the same way but I would
guess that they are. Anyway,
the AC FAN as a 10mm nut that secures the fan to the shaft, under the
fan there is a washer that sits on top of the motor shaft. I made a BIG
mistake when I put the fan on the new motor. I put the fan on the
shaft, then the washer, then the 10mm nut.
Reinstalled it on the car and the motor went up in smoke! Luckily the
Honda dealership exchanged for me ONLY because the company that I work
for does a lot of business with them. Normally there is NO exchange or
refunds on electrical parts.
So just make sure you put that washer (if it has one) underneath the
fan and not on top. And make sure the blade turns freely. If the washer
isn't installed under the fan when you tighten down the nut the fan
blade will not turn.
