2002 Sonata A/C Problem
I have a 2002 Sonata with 75,00 miles on it. Yesterday I used the a/c
with no problem. I then used the heater later that night. Now I can
only get it to blow hot air. No matter what setting I use, hot air
comes out of the vents. The compressor seems to be running and the
lines coming from it are very cold. I think maybe the heater switch is
stuck or something. Can anyone help? Thanks.

Sounds like the dampers that control air flow are not working. There is a
"blend door" that may be sticking or the controls not working. .

You'll just need to stuff your head under the dash and look up at the
heater box. If there are cables attaching to it from the heater control,
you have cable-operated heater controls. Make sure the cam (the piece to
which the cable attaches) is in place, the cable ring is attached, and the
cable is clipped properly onto the heater box.

I looked underneath the dash and near the center there is a plate with
a slot in it with a pin hanging down in one end of the slot. . When the
car is on heat the pin is in one side of the slot. When I switch it to
ac the plate moves about a half inch and the pin moves toward the other
end of the slot. I am assuming that it should move all the way to the
end of the slot to let ac air through. I tried to force it around but I
can't get it to budge. I don't see any cables but it looks like some
white gears on the other side of the plate that are controlling its
movement. Not sure if I explained that well enough or not. Thanks for
your help.
