I have no heat it just stop blowing heat and went to blowing cold air no matter what mode I am in. The dealer can't get the car in until Thursday. I cannot drive the car because of snow and freezing rain. Code 23 is the blend door actuator feedback failure. Is this something I can fix? If so where is this actuator located. This is a 2001 Dodge Intrepid ES with 28000 miles on it. What really strange I also have a 2002 concord limited and the same thing happen to it a day later. Both have ATC. Is there a way to force it to blow warm or hot air?
