Wouldn't it be wonderful if someone would read the question, and if they know the answer or a good suggestion as to try. How often do you think someone would say "Oh you were right the temperature was set to cold, thats why it blows cold air".
I have the problem of "driver side cold, passenger side hot" Both sides are set to cold. There is a control that regulates this under the hood. One of the coils is open. I can't determine what it's name is so I can get a part number. If anyone can help with this I will appreciate it.
