climate control FC and now no cold air

[M-type]

so i heard about this thing that turning your a/c down to 18C and then holding it down for 2 seconds or so activates FC (fast cold?) turning on recirc super fast blower and reallly really cold...

so i tried it and it works but now when regular a/c auto gets turned on it selects foot cooling speed 3 an not cold
if i then change modes to face cooling its warm air..

but if i activate fc its cold air again???

i have re set ecu already and it didnt change

maybe a relay stuck open or fried??
or i broke my a/c in which case delete?

R32 and R33 both have Climate Control Self-Diagnostics. Find and Download "The Sky Is The Limit" a book of Skyline stuff. Its layd out pretty nicely in there. Also can be found in R32 GTR Service manual or R33 Service Manual. Also, Im sure google has it somewhere.

If you find the answer I would love to know. Same thing with my car.

i thought FC stood for fu*king cold. lol and it works the other way to if you hold it up it becomes FH.

Check the service manual which can be found in my signature. All the diagnosis procedures are found in there.
