If you happen to know the size of the thread and thevdesured setpount, I can probably recommend a suitable switch( unlikely to be from a native MB application).
If you've installed a thermo sensor, its thevwrong conponent and will never give satisfactory results. A thermosensor has to wirk with a digital control, not a simple relay. Addind a resistor is just wrong, you're mixing and matching incompatible designs.

I'm using Mercedes A 0085424517 Water Temperature. Sensor. When adding a resistor across the terminals it does cause the fans to trigger sooner by changing the values of the resistance. I have tested this by adding a resistor that significantly dropped the resistance which caused the fans to almost turn on immediately on the stock set up, so I'm sure that the components I'm using are correct. However, there is a fault somewhere in my set up that I haven't figured out yet. I like the reverse set up idea, I may incorporate that.
