924 AC operation question

[awilson40]

Hi Gang,
My 1982 924's AC works fine, but am I missing something?? Is there a way to set the controls so the AC will recirculate inside air?? When its 90 deg outside I get 60 deg air out the vents... a 30 deg drop which is good, but it is drawing outside air all the time anmd doesnt drop the inside temp much. Also... the large temp control knob... how does it regulate the temp. Even in cooler weather, it never cycles the AC off/on... the knob seems to have no effect. Thanks
