Sorry for forgetting the year of my SHO.
It is an '89, all stock with 277,000 mi.
I obtained the info (part number and price) for the blower control module from Ford Parts network.
For the blower door actuator motor, they sent me the Ford drawing of everthing that's behind the dash with part numbers and I was to locate that specific part and give them the number for pricing. But I can't define which part is the actuator from the drawing - i.e. I'm not intelligent enough to figure it out from the drawing.
Regarding the Ford dealer, everytime I call them, they won't give me the part number, just the price, when I tell them what I want by description.
They said if they gave me the part number, then I would just shop around to get the lowest price.
I always thought that's how they operated, but perhaps, others have had different experiences.
