Hello, sounds like you may have a temperature blend issue, which can be caused by multiple sources. One major source would be a temperature blend door actuator which meters the temperature as desired from hot to cold. If it's not working you will get too much of something, hot or cold. That entire system should be evaluated using a diagnostic tool able to interface with it.
