Thanks for the tips.  Its working now.  Here's what I did:

Ran the diags from the service manual. While doing so, I noticed that
the fan would only run if I gave it a little spin.  It still ran slow
though.  So OK, bad motor.  I took it out to try and rebuild the motor
(I did this succesfully on older Honda).  Before I was to take the
motor apart, I  hooked it up straight to battery just to make sure.  It
ran great.  Hooked it back up to connector.  Ran the diags again.
Everything worked fine.  I guess the jiggling to remove the fan freed
up some hung up brushes.  I had a similar problem on the alternator
last fall. I removed a couple screws, jiggled the brush holder and
alternator has been fine since.  A EE friend of mine says this is
common with small motors as the brushes wear down.  They hang up and
the spring can't seat them properly on the commutator.  A little jiggle
frees them up and they may run trouble free for a long time after that.
