Unhappy Fan Control Module 2000 dutchstar

I have the freightliner XC chassis and am looking for the fan control module. My fan works if I pull the pug on the solenoid for the fan. FC sent me the diagrams but I cannot locate the module, I found the coolant low level module wrapped in a plastic bag hanging from ty wraps. The system uses data wires from the engine ECM to give the solenoid a ground and activate the fan thru the fan control module

On our 2000 DSDP on FL chassis it was attached to the back cap, about centered and had two wires, When one wire is detached the fan runs at full speed all the time. Open the "hood" and look straight down.

We traded the rig in in '02 so I'm going from memory here. You could also call FL as I had to when the module failed and the engine overheated. That allowed me to keep driving but with a lit more noise and less fuel mileage.

That's the control solenoid not the fan control module. I had to disconnect that to get home from San Antonio

Just had to replace mine last summer, if the 2000 is the same as 1999. The fan module was under the bed ( no bedroom slide) the module was the first in line of 5 down the right side of the engine bay. 1" thick by 5" square. Kypsor Medalion was the brand name. Note the solinoid is a no power default type. If the module supplies no power to the solinoid , the fan runs full speed, module has a battery and an ignition feed, so check all your fuses before you fault the module. When I got my part F/L told me it was 1 of 4 left, do not throw the old module out it may be repairable. A burnt out MOSFET diode on the circuit board was at fault on mine , a $5 part. I will replace the part and test the module for a spare.Good Luck.
