I don't know if this will be helpful or not....but did it work when the weather was warmer?  I have the stock cruise control in my '89 Syncro GL, and whenever it gets cold it doesn't work (which means here in northeast Florida anytime it gets below 60 F....ok, ok, all you people in the great white north can stop laughing now!).  In fact, I never knew it worked until I moved to Florida, because it didn't work at all in the north.  Works like a champ here (above 60F).
  What could it be about cooler temperatures that makes it inop?

Pedal switches good.

Removed vacuum pump and put 12V to it. It runs noisily, but doesn't
seem to pull any discernible vacuum.

Should it pull enough to hear a smack when a finger is removed from
the vacuum side? Mine is too weak for that.
