I have read many forums on this but I'm still puzzled at how this system fails after I've sent it to 2 dealers and now a 3rd mechanic and still there is a problem.
I have replaced the Heater Core, Flushed the HVAC system, no leaks when refilled, replaced the Radiator, replaced the Blend Door Actuator/Motor. The doors are moving however I can't get any heat. Cold air is fine.
Now I'm having to remove the entire dash, steering column, to get to the Blend Doors, themselves.
Can someone tell me if I'm doing this correctly and what's the next step?
