Heater Fan Speed Resistor Board

Does anyone know what component is under the little bogey on the fan speed board. I am suspecting it is a surface mount resistor, the only doubt in my mind is that all the current for the fan motor would be running through this (in first three speeds) and it seems too small watt wise.

I've compared a working and non working one and the resistance of the component can't be measured with a normal multimeter, ie less than 0.1ohms. So now maybe I'm thinking its some kind of thermal trip.

Anyone repaired one with any success?
