THANK YOU TOM !!!
I have been anxiously awaiting this development and am ready to plug it in.
I've got what might be an early version of the Mercedes fan controller - the temperature setting is done with a small wooden screwdriver (toothpick).
I don't immediately recall where the temperature sensor is - but I kinda recall that it's in the christmas tree hole (TVS).
Might I be so lucky such that this is an easy replacement ?? ie very similar wiring...

So how healthy is it for the fan clutch valve to be rapidly opening & closing like that switch in your demo video? I would love to know how Mercedes manages it in their computer software. Sent from my U.S.Cellular© Smartphone
