My 03 Grand Caravan AWD has a problem with the AWD. The rear wheels
never kick in -this worked fine last winter - I just noticed the
problem because of the show we just got - the problem may have been
around for quite a while without my noticing it. It essentially acts
like a front wheel drive van now - terrible in the snow. Any advice
would be appreciated. It still has the 7/70K powertrain warranty in
effect - Hopefully it would be covered if I have to bring it in.
