Every now and they when the heater is in use the display on the climate control unit will turn bright yellow ( instead of orange ) , start blowing cold air out of the heater ducts and then stops working . Usually it will restart and be fine but today it is dead . Anyone have this problem and how did you fix it . There are some dead pixels on the climate control unit when it does work but i hate to purchase a new one if that isnt my problem . thanks
