I found several YouTube videos on calibrating it and… apparently it is not calibrating successfully. It ends with the Recirc and AC lights flashing.
I tried both button combos: (a) Rear Wiper & Wash, (b) Wash & AC. Both end with the Recirc/AC lights flashing.
One video showed the fan off, another on high. I tried (a & b, above) but got the same results either way with the fan.
Fan speed on 4 (of 5) is still OFF. When Temp switched to hottest, the air output is minimal, though I can still hear the fan.
One video showed the text for running this calibration but not the complete text, only a bit. I’d love to see more of that. Maybe the Recirc/AC blinking is a code?
BTW, turning the key to off stops the blinking and they don’t blink again unless I run the test/calibration.
