I've got a 1991 BF5 here in NZ with climate control, and while I've had the aircon serviced, the system is still pretty dumb. I get harsh steps of changes in temperature rather then by the degree.
As you guys in the US most likely use the A/C a tad more then us here, I was wondering if anyone had any suggestions on what to try? I belive that the grille on the controls houses a sensor. Can these gunk up or something??
