Aircon Heater issue

[kryptonite]

Hi Guys,

Just took the car in for a minor service and not sure if it related in any way.

Strangely the heater seems to only work on the 2 vents for passenger.
Heater for legs works for both sides.

Also noticed that the fan for clearing up the windscreen fog now blows warm air (didnt do this before)

Anyone think of what is wrong here?

it blows hot or cold depending on temperature outside (or inside) I think

When on auto blows from the side vents when on manual pointed at the face should come through all

are you guys getting warm air from the windscreen fans? (used to defog the windscreen)
