can anyone tell me why the heater blowers won't work on a focus diesel bought as a run around by my son. i have checked fuses and relays (i think i've checked the right ones). where else would i start looking before i get to stage of taking motor out. thanks. the air con light is on if that helps.

 

Quite a common one is the resistor pack failing but leaves it working but only on speed 4.

If it is not working at all then as you've done, fuses (I'm not sure which one) or the motor itself.

 

thanks colin, will do some investigation before i attempt removal of the blower motor.
