Just the other day I got in my car and the heater was blowing ICE cold air after the car should have been warm. So I pulled the climate control box out of the dash and wiggled the wires to see if there was a bad connection. I then turned the heat all the way down to 60 and slowly went back up to 90 and the heat came on but then even when I turned it back down to 60 it stayed really hot like it was stuck on 90. The blend door was replaced last year and the heater core was replaced a month ago and the heat has worked fine. Do you guys think the blend door is sticking again or maybe the controls to adjust the heat and air are bad?? this car is equipped with the semi auto temp control so any help would be great, ITS COLD OUTSIDE!!!!!!!
 
the first thing to do is check if you have air in the system or you are low on coolant. purge the system by loosening that yellow thingy and flush it
