Al, It sounds like the thermostat. I had the same problem in my '99 Quest last year and replaced it myself. It was a pain. Not a good job for someone with large hands since it's in a tight space. The thermostat is mounted vertically on the passenger side of the engine under and behind the cooling hoses.
There is an excellent Villager/Quest group on Yahoo. There's lots of postings on replacing the thermostat there. But if I had to do it again, I'd just pony up the bucks and have a pro do it. Hope this helps. Tom
