I just thought the directional switch on the heater didn't work well (air kind of blows out the vents and to the dash all the time, no matter the setting) and the A/C doesn't work. But today my feet were ice cubes while my daughter's face was getting red and sweaty, so I let her drive (ARGH!) us home, which was my first trip in the passenger seat of my '04. And the floor heater vent was divine over there! So where do I start? Like the later model cars, are we talking a blend door issue, or is it more like my older cars with actual tubular vents that need to be checked? Thanks.
