Sons cooling fan has stopped working on the Saxo VTR fan seems ok but the fan switch in the rad has 3 wires on it, any idea what is what with this. I have 1 live on it are the other 2 an earth and a switch to the fan?

George

might be a 2 speed fan switch?

You can test the switch & fan by connecting the live to each of the other connection in turn.

I suspect you will find it is the fan relay or if it is a two brush motor the speed control resistor.

Found a drawing of the 106 setup looks the same so will try out suggestions to test.
