R45 2004 facelift climate control fault

The heater blower fan on my 2004 facelift Rover 45 TD Club SE 113ps only works intermittently. The blower motor works OK when connected to 12VDC. There is no resistor pack as on earlier models.

I require the wiring diagram to fault find the problem. The Haynes manual has no info for the facelift models with the semi automatic climate control.

Any ideas please.
