Hi,my name is mike and I will assist you with your question. The issue that you are describing Is a failed blend door motor/heater actuator. This is a small motor inside of the dash that switches the air from cold to heat and when failed is stuck on one or the other. The motor will need to be replaced to fix the issue.
