1996 Buick Park Avenue Question: The climate control module is only showing the c and the f why?

I even replaced it and it is doing the exact same thing what is wrong with it or is it something else? -
Answer 1
Sounds like it wants to know which temp. scale you want use! Got manual? Can be scanned at a repair shop. -
Answer 2
my 19096 buick park avenue AC blows out the defrost and floor only and will not change over to dash vents what can be done to fix -
Comment 1
Auto or manual system: possible dash control unit, control module, actuator motor or wiring problem. Scan test required, not DIY ! -
