It was bound to happen sooner or later. One of the least favorite jobs of a mechanic is anything involving the heater core or evaporator. It was my turn.

The heart of the HVAC system is buried deep behind the dashboard. Replacing any part of it besides sometimes the door motors or the blower motor usually requires removing the entire dashboard. Most often I see heater cores being replaced, but in my case I had to replace the entire unit that houses the heater core and evaporator and contains the doors that control which vents the air blows to and what temperature it is. For my first time, it took me and an assistant six hours to take the dash out and put it back in.
