Hello,
I got my GS300 back from an electrical repair and the A/C would not blow out of either the face/feet vents even when the arrows point to it.
I entered the diagnostic menu (Auto + Recirc when turning ignition on) and the errors 21,24,41,43,46 flashed continously. Then by chance I pressed the Auto button and the unit performed some sort of self-recalibration of its motors / position sensors!
This cleared the 41,43,46 codes, but I still have the 21 and 24 codes. Does anybody know what these mean?
