Hi,

I have been replacing items to try and get this to work as it just stopped working.

The heater control unit on the facia lights up when I press/turn anything.
The actual fan is working as I've connected it to 12v and it's fine.
The heating elements and automatic vent flaps are ok.

So, I changed the resistor pack on the blower unit from one I found on ebay (reproduction I think).. This made no difference. Thinking that part may be faulty from 'ebay' they sent another one again, it made no difference.

My next step, out of desperation, was to source a used heater control unit to replace my existing unit that appeared to light up and work. So I found one and fitted it but guess what... Still blower not working. (Even after I disconnected the battery and reconnected to see if it cleared).

As I've changed the only two things that I can think of, does anyone have any idea what the cause may please?

Thanks.
