hey guys I have a 1990 VN calais V8 with no heater control at all, lots of posts about the resistor under the windscreen wiper cover. I have checked the resistor and it is fine, I tested the main wires to the fan itself they have no power, I also powered the fan with 12v directly and it powers up.

Can anyone please point me in the right direction or if they have any ideas please share ? this calais of mine also has climate control
