There is a blend door actuator that is probably malfunctioning.
Just had this happen to me took to dealer blend door was working ok. They flushed the heater core and is much better. I feel a new heater core is in the future. Left side was blowing 126 degrees 55 on the right. Now it's 125 and 110.
It's very closed up underdash, is there a mix/blend door or a valve, or what normally malfunctions when this is happening?
