The left wheel is for heat & defrost settings and the right wheel is for temp setting.

De-ice:all air goes to the windshield outlet.

De-fog:output is split between the windshield and foot outlets

Hi,
I believe the right side wheel also sends the vacuum signal to the astro-vents in ther rear deck. Cold= open, Hot= closed.
Regards,
Alan
