Hi Galambosi,
Colvert has a good suggestion here although the "thermostats" he refers to are actually servo motors driving air blending flaps on each side. These mix outside air (cooled if the air conditioning is operational) with hot air drawn through the matrix to achieve approximately the temperature you've set on the control panel.
On your passenger side you'll see the servo motor (it looks like 3 fixing screws on the diagram) located immediately above the heater coolant pipes.
Have you carried out the ATC manual diagnostic check Galambosi? With the ignition key in position '0' press and hold the AUTO and air distribution buttons then turn the ignition switch to position '2'. If the RH temperature servo motor or flap is faulty you will see the code FC32 (ignore 21 & 22 which occur when there's insufficient daylight for the sunlight sensors).
