I've searched, but can't find another post about my issue.
My HVAC blows cold with AC, Hot with heat, Defrost position works as does dash vents and floor......
I can vary the temperature between cold, hot and anywhere in between......
BUT...
I can only select ONE position for the air to come out of.
The airflow is binary.
If I press the button up once, the lights cycle all the way to the top (left button for dash vents or right button for defrost).
If I press the button down once the lights cycle all the way to the bottom ... you get the idea.
I can't select a mid point for air to be split part way. Does this make any sense?
Any ideas?
Thanks for any input.
