Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here. The temperature is controlled by the temp control cable and I would start with making sure its adjusted properly and actually closing the blend door while in the cold position. I have enclosed the set for adjusting and or replacing if need be in the link below.
