Hi gang, my brother was having a/c blower problems so I thought I would be smart and use my wife's controls out of her 1500 to see if it was his blower switch. After we put the dash center back in the wife's truck now the a/c light will not light up ( the a/c is working) and the heated mirror light flashes. I know there's some way to make it recalibrate but I'm not sure how. I tried unhooking the battery and the switch panel overnight and that didn't make it relearn. Anyone know the sequence?
