Just spoke to a vw head technician. Turns out there should be a 449 relay in the tip slot and it's been removed for some reason. Nothing to do with turning the door dial to heat and put rear screen button on too to get them to work.
Gonna test the wires with a multi meter before putting a relay in. Must have been removed for a reason and the technician warned me to check the wires first incase of a short to ground
