My 97 Quest takes 20 plus minutes to put out any heat and even then not when
idling, only when driving or rpm is about 1000. We're in NW Montana and
need that heater. Not sure it has any bearing but in the Summer the a/c also
takes awhile to cool. My wife has a 89 Corsica and it heats and cools
almost immediately. No snow tires on it so need to fix Quest heat problem.

I think it may be the thermostat? If so where is it and is it possible for
me to change without a major project? I've done some mechanical work on
vehicles over the years but at 70 and on SS I only do simple jobs like
plugs, filters, etc. And shovel snow, 15" in Libby, MT.

Any idea's? Any help is greatly appreciated to fix the problem. Spouse
will also appreciate since I take her to work 3 nights a week.

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
