Hi Gordon. Just noticed your car being a 2014 model may be an early GDI engined one with BCU controlled heater fan motor. If so then my and Rog's previous comments don't apply.

Assuming it is the later model then the fan selector switch places a ground on either a slate wire (slow) or yellow wire (fast) which in each case is sent to the BCU as a trigger. The BCU in turn then powers either a green/slate wire or green/yellow wire to heater fan motor for slow/fast respectively. You could check the green/yellow wire plus connectors for short between BCU and fan motor. If nothing sinister found then maybe just increasing fuse 11 size from 10 to 15 amp may offset a marginal condition, as this protects the fan power into BCU.
