My sonata has the automatic climate control without ***** and without the
cabin filter. The fan will only turn on if you select the highest speed. All
the other functions seem to work like normal, meaning no matter what the fan
speed is set at I can change modes for the vent positions, temp control, AC
on or off, ambient outside temp. Obviously the Auto mode doesn't work to
control the fan either, but it does change the vents and the L.E.D. fan
speed indicator changes as I change the temperature settings. Does this mean
that the climate control is bad or is there something else wrong such as
sensor, wiring ect...

Thanks,
Dave
