So I replaced the fan in my '14 W212 because a jack mishap damaged the shroud. Not good enough for the Mercedes, but it's still good enough to transplant into my TR6. So, I replaced the fan but have a usable spare, with some JB Weld. I really want to use this one because it's so QUIET. Aftermarket stuff, and even other junkyard fans I've used, sound like Cessnas.

I have four wires going into the fan controller attached to the shroud - two thick and two thin. I can probably get away with just taking the controller out entirely and just wiring the two leads from the fan motor to a thermostatic switch and calling it good. However, I'm wondering if that's a resistor pack on the fan shroud there, and the two thin wires are maybe triggers for high and low speed? Or what? Anyone know what the wiring diagram for a W212 fan looks like?

Thanks,
Darel

My fan on the W211 and W212 don't sound like a Cessna; they sound like a damn F-16 when at high speed. Are you sure about this QUIET thing?
