Neither my AC nor my heat works. In the summer I'm burning up and in the winter I'm freezing. The buttons on the control module don't seem to do anything. And then, randomly, the blower will come on full blast, and I can do nothing to stop it except for turning the car off. And that's not ideal when traveling down the highway. I switched out the "head unit" in the dash with my other 80 that currently isn't running to no avail. Does any of this sound familiar or am I uniquely cursed with this heat and air issue?
