My 1990 Dodge Spirit with 67K orig miles  was producing little or ne
heat. My local garage deteremined it needed a new heater core. That
restored the heat just fine. I noticed a lot of condensation on the
inside of the windows the day I picked up the car from the garage, but
chalked it up to the damp weather that day. After warming up the car
on cold winter days, the windows wouild get dry, bu as soon as I got
inside the car adn drove it for a few miles, the inside of the windows
started to fog up. This would only happen on day when there was
precipitaion, not dry days. My mechanic
suggested that I simply air out the car by leaving the windows open in
dry weather, saying that some antifreeze
had probably spilled into the air passages when the heater core was
being replaced. Another issue was that the heat only came out of the
windshield defroster/floor mode, regard-
less of what mode button I pressed on the heater control
panel. I took the car back in to the shop. They said there were cracks
in the blower housing box,which were already there when they first
worked on the car. They glued the cracks with epoxy, and told me the
box would have to be replaced if that did not work. Well, now I have
two problems,
condensation on inside windows in rain or snow conditions, and heater
controls that only work for windshield and floor
mode.  I noticed that the only way to make the air come out of the
dash air outlets is to turn the heater control lever all the way to
the left, to the "recirculate" mode (used for AC)/ and turn the AC
button on! Does anyone have any suggestions?
