Front of the car off and had a look at the fan, 4 wires leave the control box and go in to the fan, would that be a 3 speed fan? The fan control box has three relays(?) inside. I have disconnected the wiring to the fan, the piggy back job on the chassis rail, if I reconnect that and try the demist test I should hear one of the relays click, would that be right?
Also, no sign of a resistor, the usual mounting point shows no evidence of holes ever having screws in them. More evidence of a three speed fan?
