Actually, I was referring to this one - "blower regulator."

But please don't take my word for this. The whole system is one big expensive black box. I would hate to see you spend a couple of hundred bucks on an unnecessary part. I would suggest getting the schematic and seeing if your dash unit is sending a signal to the blower control.

I have the amplifier shown as a part in my 560 as well, but it doesn't seem to be on any of the schematics. The older cars with the servos used this part, though.
