Glenn,
Thanks. I've saved the info you supplied for future reference. By the
way,
I do not own a scan tool and have never had this vehicle to the dealer for
any service. I did just replace the battery (it was 6 years old) and had
the old one out for ten or more minutes before getting the new one
installed, and this had no affect on the situation.
So I've got two things to check: 1) A/C drain and 2) recirculation door.
As to there being moisture in the passenger compartment, I do have the
heavy
floor mats in there that catch the snow and water and they do retain some
moisture, but I have these in other Chrysler vehicles and used similar
models in my previous car, which was a 1996 LH and had no problems. I've
got a couple things to look at when the weather improves. If that does
not
work then it will go to the dealer to be scanned!
Thanks to all for the replies.
Bob
