One blower blowing cold

[Djwalshaw]

Good afternoon,

I have a Seat Leon MK3 2015 right hand drive. When the heat is turned up, the right hand side centre heater blows luke warm whilst the left side centre blows hot, as does the driver and passenger sides.

I can see an actuator in the passenger footwell which moves from hot to cold with no issue, yet I can't see to find any other actuators. Does anyone know where they are hidden please? I can't find anything on YouTube either.

When plugged in it shows a sporadic code B109d71 code.

Thanks in advance!

Have you reset the actuators ?
