Blower Control

[Dark72]

Does anyone know what controls the blower motor to turn on automatically when key is turned to accessory, or when running you pull back to idle?

On what boat?  Your profile lists a '98 Response LX, but my '99 Sunsetter LX doesn't do that.  The blower switch is on the dash.

98 Response LX is correct. I have a blower switch on the dash as well that I can turn on mechanically.  I was able to find that the blower turns on automatically under 1500 RPMs in a manual, however it does tells what controls that trigger point. Had to replace the MDC 1600 due to it got fried and none of the gauges worked now all do, except blower on automatic and all of warning lights on MEMS display stay on. Now I am guessing the MEMS display that is sealed with a foam like material and no part number has also been fried, does anyone know a part number or a place to acquire one?
